-<p>This tutorial guides you to create CarbonData Tables and optimize performance.

-<p>For example, the results of the analysis for table creation with dimensions ranging from 10 thousand to 10 billion rows and 100 to 300 columns have been summarized below.
-The following table describes some of the columns from the table used.</p>
-<ul>
-<li><strong>Table Column Description</strong></li>
-</ul>
-<table>
-<thead>
-<tr>
-<th>Column Name</th>
-<th>Data Type</th>
-<th>Cardinality</th>
-<th>Attribution</th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>msisdn</td>
-<td>String</td>
-<td>30 million</td>
-<td>Dimension</td>
-</tr>
-<tr>
-<td>BEGIN_TIME</td>
-<td>BigInt</td>
-<td>10 Thousand</td>
-<td>Dimension</td>
-</tr>
-<tr>
-<td>HOST</td>
-<td>String</td>
-<td>1 million</td>
-<td>Dimension</td>
-</tr>
-<tr>
-<td>Dime_1</td>
-<td>String</td>
-<td>1 Thousand</td>
-<td>Dimension</td>
-</tr>
-<tr>
-<td>counter_1</td>
-<td>Decimal</td>
-<td>NA</td>
-<td>Measure</td>
-</tr>
-<tr>
-<td>counter_2</td>
-<td>Numeric(20,0)</td>
-<td>NA</td>
-<td>Measure</td>
-</tr>
-<tr>
-<td>...</td>
-<td>...</td>
-<td>NA</td>
-<td>Measure</td>
-</tr>
-<tr>
-<td>counter_100</td>
-<td>Decimal</td>
-<td>NA</td>
-<td>Measure</td>
-</tr>
-</tbody>
-</table>
-<ul>
-<li><strong>Put the frequently-used column filter in the beginning</strong></li>
-</ul>
-<p>For example, MSISDN filter is used in most of the query then we must put the MSISDN in the first column.
-The create table command can be modified as suggested below :</p>
-<pre><code>create table carbondata_table(
- msisdn String,
- BEGIN_TIME bigint,
- HOST String,
- Dime_1 String,
- counter_1, Decimal
- ...
-
- )STORED BY 'carbondata'
- TBLPROPERTIES ('SORT_COLUMNS'='msisdn, Dime_1')
-</code></pre>
-<p>Now the query with MSISDN in the filter will be more efficient.</p>
-<ul>
-<li><strong>Put the frequently-used columns in the order of low to high cardinality</strong></li>
-</ul>
-<p>If the table in the specified query has multiple columns which are frequently used to filter the results, it is suggested to put
-the columns in the order of cardinality low to high. This ordering of frequently used columns improves the compression ratio and
-enhances the performance of queries with filter on these columns.</p>
-<p>For example, if MSISDN, HOST and Dime_1 are frequently-used columns, then the column order of table is suggested as
-Dime_1>HOST>MSISDN, because Dime_1 has the lowest cardinality.
-The create table command can be modified as suggested below :</p>
-<pre><code>create table carbondata_table(
- msisdn String,
- BEGIN_TIME bigint,
- HOST String,
- Dime_1 String,
- counter_1, Decimal
- ...
-
- )STORED BY 'carbondata'
- TBLPROPERTIES ('SORT_COLUMNS'='Dime_1, HOST, MSISDN')
-</code></pre>
-<ul>
-<li><strong>For measure type columns with non high accuracy, replace Numeric(20,0) data type with Double data type</strong></li>
-</ul>
-<p>For columns of measure type, not requiring high accuracy, it is suggested to replace Numeric data type with Double to enhance query performance.
-The create table command can be modified as below :</p>
-<pre><code> create table carbondata_table(
- Dime_1 String,
- BEGIN_TIME bigint,
- END_TIME bigint,
- HOST String,
- MSISDN String,
- counter_1 decimal,
- counter_2 double,
- ...
- )STORED BY 'carbondata'
- TBLPROPERTIES ('SORT_COLUMNS'='Dime_1, HOST, MSISDN')
-</code></pre>
-<p>The result of performance analysis of test-case shows reduction in query execution time from 15 to 3 seconds, thereby improving performance by nearly 5 times.</p>
-<ul>
-<li><strong>Columns of incremental character should be re-arranged at the end of dimensions</strong></li>
-</ul>
-<p>Consider the following scenario where data is loaded each day and the begin_time is incremental for each load, it is suggested to put begin_time at the end of dimensions.
-Incremental values are efficient in using min/max index. The create table command can be modified as below :</p>
-<pre><code>create table carbondata_table(
- Dime_1 String,
- HOST String,
- MSISDN String,
- counter_1 double,
- counter_2 double,
- BEGIN_TIME bigint,
- END_TIME bigint,
- ...
- counter_100 double
- )STORED BY 'carbondata'
- TBLPROPERTIES ('SORT_COLUMNS'='Dime_1, HOST, MSISDN')
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>BloomFilter can be created to enhance performance for queries with precise equal/in conditions. You can find more information about it in BloomFilter datamap <a href="https://github.com/apache/carbondata/blob/master/docs/datamap/bloomfilter-datamap-guide.html" target=_blank>document</a>.</li>

-<p>CarbonData supports large data load, in this process sorting data while loading consumes a lot of memory and disk IO and
-this can result sometimes in "Out Of Memory" exception.
-If you do not have much memory to use, then you may prefer to slow the speed of data loading instead of data load failure.
-You can configure CarbonData by tuning following properties in carbon.properties file to get a better performance.</p>
-<table>

-<tr>
-<th>Parameter</th>

-</thead>
-<tbody>
-<tr>
-<td>carbon.number.of.cores.while.loading</td>

-</tr>
-</tbody>
-</table>
-<p>For example, if there are 10 million records, and i have only 16 cores, 64GB memory, will be loaded to CarbonData table.
-Using the default configuration always fail in sort step. Modify carbon.properties as suggested below:</p>
-<pre><code>carbon.number.of.cores.block.sort=1
-carbon.merge.sort.reader.thread=1
-carbon.sort.size=5000
-carbon.sort.file.write.buffer.size=5000
-carbon.merge.sort.prefetch=false

-<p>Recently we did some performance POC on CarbonData for Finance and telecommunication Field. It involved detailed queries and aggregation
-scenarios. After the completion of POC, some of the configurations impacting the performance have been identified and tabulated below :</p>
-<table>
-<thead>
-<tr>
-<th>Parameter</th>
-<th>Location</th>
-<th>Used For</th>
-<th>Description</th>
-<th>Tuning</th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>carbon.sort.intermediate.files.limit</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>During the loading of data, local temp is used to sort the data. This number specifies the minimum number of intermediate files after which the merge sort has to be initiated.</td>
-<td>Increasing the parameter to a higher value will improve the load performance. For example, when we increase the value from 20 to 100, it increases the data load performance from 35MB/S to more than 50MB/S. Higher values of this parameter consumes more memory during the load.</td>
-</tr>
-<tr>
-<td>carbon.number.of.cores.while.loading</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Specifies the number of cores used for data processing during data loading in CarbonData.</td>
-<td>If you have more number of CPUs, then you can increase the number of CPUs, which will increase the performance. For example if we increase the value from 2 to 4 then the CSV reading performance can increase about 1 times</td>
-</tr>
-<tr>
-<td>carbon.compaction.level.threshold</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading and Querying</td>
-<td>For minor compaction, specifies the number of segments to be merged in stage 1 and number of compacted segments to be merged in stage 2.</td>
-<td>Each CarbonData load will create one segment, if every load is small in size it will generate many small file over a period of time impacting the query performance. Configuring this parameter will merge the small segment to one big segment which will sort the data and improve the performance. For Example in one telecommunication scenario, the performance improves about 2 times after minor compaction.</td>
-</tr>
-<tr>
-<td>spark.sql.shuffle.partitions</td>
-<td>spark/conf/spark-defaults.conf</td>
-<td>Querying</td>
-<td>The number of task started when spark shuffle.</td>
-<td>The value can be 1 to 2 times as much as the executor cores. In an aggregation scenario, reducing the number from 200 to 32 reduced the query time from 17 to 9 seconds.</td>
-</tr>
-<tr>
-<td>spark.executor.instances/spark.executor.cores/spark.executor.memory</td>
-<td>spark/conf/spark-defaults.conf</td>
-<td>Querying</td>
-<td>The number of executors, CPU cores, and memory used for CarbonData query.</td>
-<td>In the bank scenario, we provide the 4 CPUs cores and 15 GB for each executor which can get good performance. This 2 value does not mean more the better. It needs to be configured properly in case of limited resources. For example, In the bank scenario, it has enough CPU 32 cores each node but less memory 64 GB each node. So we cannot give more CPU but less memory. For example, when 4 cores and 12GB for each executor. It sometimes happens GC during the query which impact the query performance very much from the 3 second to more than 15 seconds. In this scenario need to increase the memory or decrease the CPU cores.</td>
-</tr>
-<tr>
-<td>carbon.detail.batch.size</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>The buffer size to store records, returned from the block scan.</td>
-<td>In limit scenario this parameter is very important. For example your query limit is 1000. But if we set this value to 3000 that means we get 3000 records from scan but spark will only take 1000 rows. So the 2000 remaining are useless. In one Finance test case after we set it to 100, in the limit 1000 scenario the performance increase about 2 times in comparison to if we set this value to 12000.</td>
-</tr>
-<tr>
-<td>carbon.use.local.dir</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Whether use YARN local directories for multi-table load disk load balance</td>
-<td>If this is set it to true CarbonData will use YARN local directories for multi-table load disk load balance, that will improve the data load performance.</td>
-</tr>
-<tr>
-<td>carbon.use.multiple.temp.dir</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Whether to use multiple YARN local directories during table data loading for disk load balance</td>
-<td>After enabling 'carbon.use.local.dir', if this is set to true, CarbonData will use all YARN local directories during data load for disk load balance, that will improve the data load performance. Please enable this property when you encounter disk hotspot problem during data loading.</td>
-</tr>
-<tr>
-<td>carbon.sort.temp.compressor</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Specify the name of compressor to compress the intermediate sort temporary files during sort procedure in data loading.</td>
-<td>The optional values are 'SNAPPY','GZIP','BZIP2','LZ4','ZSTD' and empty. By default, empty means that Carbondata will not compress the sort temp files. This parameter will be useful if you encounter disk bottleneck.</td>
-</tr>
-<tr>
-<td>carbon.load.skewedDataOptimization.enabled</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Whether to enable size based block allocation strategy for data loading.</td>
-<td>When loading, carbondata will use file size based block allocation strategy for task distribution. It will make sure that all the executors process the same size of data -- It's useful if the size of your input data files varies widely, say 1MB~1GB.</td>
-</tr>
-<tr>
-<td>carbon.load.min.size.enabled</td>
-<td>spark/carbonlib/carbon.properties</td>
-<td>Data loading</td>
-<td>Whether to enable node minumun input data size allocation strategy for data loading.</td>
-<td>When loading, carbondata will use node minumun input data size allocation strategy for task distribution. It will make sure the node load the minimum amount of data -- It's useful if the size of your input data files very small, say 1MB~256MB,Avoid generating a large number of small files.</td>

-<h2>
-<a id="create-table" class="anchor" href="#create-table" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>CREATE TABLE</h2>
-<p>This command can be used to create a CarbonData table by specifying the list of fields along with the table properties. You can also specify the location where the table needs to be stored.</p>
-<pre><code>CREATE TABLE [IF NOT EXISTS] [db_name.]table_name[(col_name data_type , ...)]
-STORED AS carbondata
-[TBLPROPERTIES (property_name=property_value, ...)]
-[LOCATION 'path']
-</code></pre>
-<p><strong>NOTE:</strong> CarbonData also supports "STORED AS carbondata" and "USING carbondata". Find example code at <a href="https://github.com/apache/carbondata/blob/master/examples/spark2/src/main/scala/org/apache/carbondata/examples/CarbonSessionExample.scala" target=_blank>CarbonSessionExample</a> in the CarbonData repo.</p>
-<h3>
-<a id="usage-guidelines" class="anchor" href="#usage-guidelines" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Usage Guidelines</h3>
-<p>Following are the guidelines for TBLPROPERTIES, CarbonData's additional table options can be set via carbon.properties.</p>
-<ul>
-<li>
-<p><strong>Dictionary Encoding Configuration</strong></p>
-<p>Dictionary encoding is turned off for all columns by default from 1.3 onwards, you can use this command for including or excluding columns to do dictionary encoding.
-Suggested use cases : do dictionary encoding for low cardinality columns, it might help to improve data compression ratio and performance.</p>
-<pre><code>TBLPROPERTIES ('DICTIONARY_INCLUDE'='column1, column2')
-</code></pre>
-<p>NOTE: Dictionary Include/Exclude for complex child columns is not supported.</p>
-</li>
-<li>
-<p><strong>Inverted Index Configuration</strong></p>
-<p>By default inverted index is enabled, it might help to improve compression ratio and query speed, especially for low cardinality columns which are in reward position.
-Suggested use cases : For high cardinality columns, you can disable the inverted index for improving the data loading performance.</p>
-<pre><code>TBLPROPERTIES ('NO_INVERTED_INDEX'='column1, column3')
-</code></pre>
-</li>
-<li>
-<p><strong>Sort Columns Configuration</strong></p>
-<p>This property is for users to specify which columns belong to the MDK(Multi-Dimensions-Key) index.</p>
-<ul>
-<li>If users don't specify "SORT_COLUMN" property, by default MDK index be built by using all dimension columns except complex data type column.</li>
-<li>If this property is specified but with empty argument, then the table will be loaded without sort.</li>
-<li>This supports only string, date, timestamp, short, int, long, and boolean data types.
-Suggested use cases : Only build MDK index for required columns,it might help to improve the data loading performance.</li>
-</ul>
-<pre><code>TBLPROPERTIES ('SORT_COLUMNS'='column1, column3')
-OR
-TBLPROPERTIES ('SORT_COLUMNS'='')
-</code></pre>
-<p>NOTE: Sort_Columns for Complex datatype columns is not supported.</p>
-</li>
-<li>
-<p><strong>Sort Scope Configuration</strong></p>
-<p>This property is for users to specify the scope of the sort during data load, following are the types of sort scope.</p>
-<ul>
-<li>LOCAL_SORT: It is the default sort scope.</li>
-<li>NO_SORT: It will load the data in unsorted manner, it will significantly increase load performance.</li>
-<li>BATCH_SORT: It increases the load performance but decreases the query performance if identified blocks > parallelism.</li>
-<li>GLOBAL_SORT: It increases the query performance, especially high concurrent point query.
-And if you care about loading resources isolation strictly, because the system uses the spark GroupBy to sort data, the resource can be controlled by spark.</li>
-</ul>
-</li>
-</ul>
-<pre><code>### Example:
-</code></pre>
-<pre><code> CREATE TABLE IF NOT EXISTS productSchema.productSalesTable (
- productNumber INT,
- productName STRING,
- storeCity STRING,
- storeProvince STRING,
- productCategory STRING,
- productBatch STRING,
- saleQuantity INT,
- revenue INT)
- STORED BY 'carbondata'
- TBLPROPERTIES ('SORT_COLUMNS'='productName,storeCity',
- 'SORT_SCOPE'='NO_SORT')
-</code></pre>
-<p><strong>NOTE:</strong> CarbonData also supports "using carbondata". Find example code at <a href="https://github.com/apache/carbondata/blob/master/examples/spark2/src/main/scala/org/apache/carbondata/examples/SparkSessionExample.scala" target=_blank>SparkSessionExample</a> in the CarbonData repo.</p>
-<ul>
-<li>
-<p><strong>Table Block Size Configuration</strong></p>
-<p>This command is for setting block size of this table, the default value is 1024 MB and supports a range of 1 MB to 2048 MB.</p>
-<pre><code>TBLPROPERTIES ('TABLE_BLOCKSIZE'='512')
-</code></pre>
-<p><strong>NOTE:</strong> 512 or 512M both are accepted.</p>
-</li>
-<li>
-<p><strong>Table Compaction Configuration</strong></p>
-<p>These properties are table level compaction configurations, if not specified, system level configurations in carbon.properties will be used.
-Following are 5 configurations:</p>
-<ul>
-<li>MAJOR_COMPACTION_SIZE: same meaning as carbon.major.compaction.size, size in MB.</li>
-<li>AUTO_LOAD_MERGE: same meaning as carbon.enable.auto.load.merge.</li>
-<li>COMPACTION_LEVEL_THRESHOLD: same meaning as carbon.compaction.level.threshold.</li>
-<li>COMPACTION_PRESERVE_SEGMENTS: same meaning as carbon.numberof.preserve.segments.</li>
-<li>ALLOWED_COMPACTION_DAYS: same meaning as carbon.allowed.compaction.days.</li>
-</ul>
-<pre><code>TBLPROPERTIES ('MAJOR_COMPACTION_SIZE'='2048',
- 'AUTO_LOAD_MERGE'='true',
- 'COMPACTION_LEVEL_THRESHOLD'='5,6',
- 'COMPACTION_PRESERVE_SEGMENTS'='10',
- 'ALLOWED_COMPACTION_DAYS'='5')
-</code></pre>
-</li>
-<li>
-<p><strong>Streaming</strong></p>
-<p>CarbonData supports streaming ingestion for real-time data. You can create the ?streaming? table using the following table properties.</p>
-<pre><code>TBLPROPERTIES ('streaming'='true')
-</code></pre>
-</li>
-<li>
-<p><strong>Local Dictionary Configuration</strong></p>
-</li>
-</ul>
-<p>Columns for which dictionary is not generated needs more storage space and in turn more IO. Also since more data will have to be read during query, query performance also would suffer.Generating dictionary per blocklet for such columns would help in saving storage space and assist in improving query performance as carbondata is optimized for handling dictionary encoded columns more effectively.Generating dictionary internally per blocklet is termed as local dictionary. Please refer to <a href="../file-structure-of-carbondata.html">File structure of Carbondata</a> for understanding about the file structure of carbondata and meaning of terms like blocklet.</p>
-<p>Local Dictionary helps in:</p>
-<ol>
-<li>Getting more compression.</li>
-<li>Filter queries and full scan queries will be faster as filter will be done on encoded data.</li>
-<li>Reducing the store size and memory footprint as only unique values will be stored as part of local dictionary and corresponding data will be stored as encoded data.</li>
-<li>Getting higher IO throughput.</li>
-</ol>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>
-<p>Following Data Types are Supported for Local Dictionary:</p>
-<ul>
-<li>STRING</li>
-<li>VARCHAR</li>
-<li>CHAR</li>
-</ul>
-</li>
-<li>
-<p>Following Data Types are not Supported for Local Dictionary:</p>
-<ul>
-<li>SMALLINT</li>
-<li>INTEGER</li>
-<li>BIGINT</li>
-<li>DOUBLE</li>
-<li>DECIMAL</li>
-<li>TIMESTAMP</li>
-<li>DATE</li>
-<li>BOOLEAN</li>
-</ul>
-</li>
-<li>
-<p>In case of multi-level complex dataType columns, primitive string/varchar/char columns are considered for local dictionary generation.</p>
-</li>
-</ul>
-<p>Local dictionary will have to be enabled explicitly during create table or by enabling the system property 'carbon.local.dictionary.enable'. By default, Local Dictionary will be disabled for the carbondata table.</p>
-<p>Local Dictionary can be configured using the following properties during create table command:</p>
-<table>
-<thead>
-<tr>
-<th>Properties</th>
-<th>Default value</th>
-<th>Description</th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>LOCAL_DICTIONARY_ENABLE</td>
-<td>false</td>
-<td>Whether to enable local dictionary generation. <strong>NOTE:</strong> If this property is defined, it will override the value configured at system level by 'carbon.local.dictionary.enable'</td>
-</tr>
-<tr>
-<td>LOCAL_DICTIONARY_THRESHOLD</td>
-<td>10000</td>
-<td>The maximum cardinality of a column upto which carbondata can try to generate local dictionary (maximum - 100000)</td>
-</tr>
-<tr>
-<td>LOCAL_DICTIONARY_INCLUDE</td>
-<td>string/varchar/char columns</td>
-<td>Columns for which Local Dictionary has to be generated.<strong>NOTE:</strong> Those string/varchar/char columns which are added into DICTIONARY_INCLUDE option will not be considered for local dictionary generation.</td>
-</tr>
-<tr>
-<td>LOCAL_DICTIONARY_EXCLUDE</td>
-<td>none</td>
-<td>Columns for which Local Dictionary need not be generated.</td>
-</tr>
-</tbody>
-</table>
-<p><strong>Fallback behavior:</strong></p>
-<ul>
-<li>When the cardinality of a column exceeds the threshold, it triggers a fallback and the generated dictionary will be reverted and data loading will be continued without dictionary encoding.</li>
-</ul>
-<p><strong>NOTE:</strong> When fallback is triggered, the data loading performance will decrease as encoded data will be discarded and the actual data is written to the temporary sort files.</p>
-<p><strong>Points to be noted:</strong></p>
-<ol>
-<li>
-<p>Reduce Block size:</p>
-<p>Number of Blocks generated is less in case of Local Dictionary as compression ratio is high. This may reduce the number of tasks launched during query, resulting in degradation of query performance if the pruned blocks are less compared to the number of parallel tasks which can be run. So it is recommended to configure smaller block size which in turn generates more number of blocks.</p>
-</li>
-<li>
-<p>All the page-level data for a blocklet needs to be maintained in memory until all the pages encoded for local dictionary is processed in order to handle fallback. Hence the memory required for local dictionary based table is more and this memory increase is proportional to number of columns.</p>
-</li>
-</ol>
-<h3>
-<a id="example" class="anchor" href="#example" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Example:</h3>
-<pre><code>CREATE TABLE carbontable(
-
- column1 string,
-
- column2 string,
-
- column3 LONG )
-
- STORED BY 'carbondata'
- TBLPROPERTIES('LOCAL_DICTIONARY_ENABLE'='true','LOCAL_DICTIONARY_THRESHOLD'='1000',
- 'LOCAL_DICTIONARY_INCLUDE'='column1','LOCAL_DICTIONARY_EXCLUDE'='column2')
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>We recommend to use Local Dictionary when cardinality is high but is distributed across multiple loads</li>
-<li>On a large cluster, decoding data can become a bottleneck for global dictionary as there will be many remote reads. In this scenario, it is better to use Local Dictionary.</li>
-<li>When cardinality is less, but loads are repetitive, it is better to use global dictionary as local dictionary generates multiple dictionary files at blocklet level increasing redundancy.</li>
-</ul>
-<ul>
-<li>
-<p><strong>Caching Min/Max Value for Required Columns</strong>
-By default, CarbonData caches min and max values of all the columns in schema. As the load increases, the memory required to hold the min and max values increases considerably. This feature enables you to configure min and max values only for the required columns, resulting in optimized memory usage.</p>
-<p>Following are the valid values for COLUMN_META_CACHE:</p>
-<ul>
-<li>If you want no column min/max values to be cached in the driver.</li>
-</ul>
-<pre><code>COLUMN_META_CACHE=??
-</code></pre>
-<ul>
-<li>If you want only col1 min/max values to be cached in the driver.</li>
-</ul>
-<pre><code>COLUMN_META_CACHE=?col1?
-</code></pre>
-<ul>
-<li>If you want min/max values to be cached in driver for all the specified columns.</li>
-</ul>
-<pre><code>COLUMN_META_CACHE=?col1,col2,col3,??
-</code></pre>
-<p>Columns to be cached can be specified either while creating table or after creation of the table.
-During create table operation; specify the columns to be cached in table properties.</p>
-<p>Syntax:</p>
-<pre><code>CREATE TABLE [dbName].tableName (col1 String, col2 String, col3 int,?) STORED BY ?carbondata? TBLPROPERTIES (?COLUMN_META_CACHE?=?col1,col2,??)
-</code></pre>
-<p>Example:</p>
-<pre><code>CREATE TABLE employee (name String, city String, id int) STORED BY ?carbondata? TBLPROPERTIES (?COLUMN_META_CACHE?=?name?)
-</code></pre>
-<p>After creation of table or on already created tables use the alter table command to configure the columns to be cached.</p>
-<p>Syntax:</p>
-<pre><code>ALTER TABLE [dbName].tableName SET TBLPROPERTIES (?COLUMN_META_CACHE?=?col1,col2,??)
-</code></pre>
-<p>Example:</p>
-<pre><code>ALTER TABLE employee SET TBLPROPERTIES (?COLUMN_META_CACHE?=?city?)
-</code></pre>
-</li>
-<li>
-<p><strong>Caching at Block or Blocklet Level</strong></p>
-<p>This feature allows you to maintain the cache at Block level, resulting in optimized usage of the memory. The memory consumption is high if the Blocklet level caching is maintained as a Block can have multiple Blocklet.</p>
-<p>Following are the valid values for CACHE_LEVEL:</p>
-<p><em>Configuration for caching in driver at Block level (default value).</em></p>
-<pre><code>CACHE_LEVEL= ?BLOCK?
-</code></pre>
-<p><em>Configuration for caching in driver at Blocklet level.</em></p>
-<pre><code>CACHE_LEVEL= ?BLOCKLET?
-</code></pre>
-<p>Cache level can be specified either while creating table or after creation of the table.
-During create table operation specify the cache level in table properties.</p>
-<p>Syntax:</p>
-<pre><code>CREATE TABLE [dbName].tableName (col1 String, col2 String, col3 int,?) STORED BY ?carbondata? TBLPROPERTIES (?CACHE_LEVEL?=?Blocklet?)
-</code></pre>
-<p>Example:</p>
-<pre><code>CREATE TABLE employee (name String, city String, id int) STORED BY ?carbondata? TBLPROPERTIES (?CACHE_LEVEL?=?Blocklet?)
-</code></pre>
-<p>After creation of table or on already created tables use the alter table command to configure the cache level.</p>
-<p>Syntax:</p>
-<pre><code>ALTER TABLE [dbName].tableName SET TBLPROPERTIES (?CACHE_LEVEL?=?Blocklet?)
-</code></pre>
-<p>Example:</p>
-<pre><code>ALTER TABLE employee SET TBLPROPERTIES (?CACHE_LEVEL?=?Blocklet?)
-</code></pre>
-</li>
-</ul>
-<pre><code>- **Support Flat folder same as Hive/Parquet**
-
- This feature allows all carbondata and index files to keep directy under tablepath. Currently all carbondata/carbonindex files written under tablepath/Fact/Part0/Segment_NUM folder and it is not same as hive/parquet folder structure. This feature makes all files written will be directly under tablepath, it does not maintain any segment folder structure.This is useful for interoperability between the execution engines and plugin with other execution engines like hive or presto becomes easier.
-
- Following table property enables this feature and default value is false.
- ```
- 'flat_folder'='true'
- ```
- Example:
- ```
- CREATE TABLE employee (name String, city String, id int) STORED BY ?carbondata? TBLPROPERTIES ('flat_folder'='true')
- ```
-
-- **String longer than 32000 characters**
-
- In common scenarios, the length of string is less than 32000,
- so carbondata stores the length of content using Short to reduce memory and space consumption.
- To support string longer than 32000 characters, carbondata introduces a table property called `LONG_STRING_COLUMNS`.
- For these columns, carbondata internally stores the length of content using Integer.
-
- You can specify the columns as 'long string column' using below tblProperties:
-
- ```
- // specify col1, col2 as long string columns
- TBLPROPERTIES ('LONG_STRING_COLUMNS'='col1,col2')
- ```
-
- Besides, you can also use this property through DataFrame by
- ```
- df.format("carbondata")
- .option("tableName", "carbonTable")
- .option("long_string_columns", "col1, col2")
- .save()
- ```
-
- If you are using Carbon-SDK, you can specify the datatype of long string column as `varchar`.
- You can refer to SDKwriterTestCase for example.
-
- **NOTE:** The LONG_STRING_COLUMNS can only be string/char/varchar columns and cannot be dictionary_include/sort_columns/complex columns.

-<pre><code>sql("CREATE TABLE origin(key INT, value STRING) STORED BY 'carbondata'")
-sql("INSERT INTO origin select 100,'spark'")
-sql("INSERT INTO origin select 200,'hive'")

-<p>Non-Transactional table data location will have only carbondata and carbonindex files, there will not be a metadata folder (table status and schema).
-Our SDK module currently support writing data in this format.</p>
-<p><strong>Example:</strong></p>
-<pre><code>sql(
-s"""CREATE EXTERNAL TABLE sdkOutputTable STORED BY 'carbondata' LOCATION
-|'$writerPath' """.stripMargin)
-</code></pre>
-<p>Here writer path will have carbondata and index files.
-This can be SDK output. Refer <a href="https://github.com/apache/carbondata/blob/master/docs/sdk-writer-guide.html" target=_blank>SDK Writer Guide</a>.</p>
-<p><strong>Note:</strong></p>
-<ol>
-<li>Dropping of the external table should not delete the files present in the location.</li>
-<li>When external table is created on non-transactional table data,
-external table will be registered with the schema of carbondata files.
-If multiple files with different schema is present, exception will be thrown.
-So, If table registered with one schema and files are of different schema,
-suggest to drop the external table and create again to register table with new schema.</li>

-<a id="alter-table" class="anchor" href="#alter-table" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>ALTER TABLE</h3>
-<p>The following section introduce the commands to modify the physical or logical state of the existing table(s).</p>
-<ul>
-<li>
-<p><strong>RENAME TABLE</strong></p>
-<p>This command is used to rename the existing table.</p>
-<pre><code>ALTER TABLE [db_name.]table_name RENAME TO new_table_name
-</code></pre>
-<p>Examples:</p>
-<pre><code>ALTER TABLE carbon RENAME TO carbonTable
-OR
-ALTER TABLE test_db.carbon RENAME TO test_db.carbonTable
-</code></pre>
-</li>
-<li>
-<p><strong>ADD COLUMNS</strong></p>
-<p>This command is used to add a new column to the existing table.</p>
-<pre><code>ALTER TABLE [db_name.]table_name ADD COLUMNS (col_name data_type,...)
-TBLPROPERTIES('DICTIONARY_INCLUDE'='col_name,...',
-'DEFAULT.VALUE.COLUMN_NAME'='default_value')
-</code></pre>
-<p>Examples:</p>
-<pre><code>ALTER TABLE carbon ADD COLUMNS (a1 INT, b1 STRING)
-</code></pre>
-<pre><code>ALTER TABLE carbon ADD COLUMNS (a1 INT, b1 STRING) TBLPROPERTIES('DICTIONARY_INCLUDE'='a1')
-</code></pre>
-<pre><code>ALTER TABLE carbon ADD COLUMNS (a1 INT, b1 STRING) TBLPROPERTIES('DEFAULT.VALUE.a1'='10')
-</code></pre>
-<p>NOTE: Add Complex datatype columns is not supported.</p>
-</li>
-</ul>
-<p>Users can specify which columns to include and exclude for local dictionary generation after adding new columns. These will be appended with the already existing local dictionary include and exclude columns of main table respectively.</p>
-<pre><code> ALTER TABLE carbon ADD COLUMNS (a1 STRING, b1 STRING) TBLPROPERTIES('LOCAL_DICTIONARY_INCLUDE'='a1','LOCAL_DICTIONARY_EXCLUDE'='b1')
-</code></pre>
-<ul>
-<li>
-<p><strong>DROP COLUMNS</strong></p>
-<p>This command is used to delete the existing column(s) in a table.</p>
-<pre><code>ALTER TABLE [db_name.]table_name DROP COLUMNS (col_name, ...)
-</code></pre>
-<p>Examples:</p>
-<pre><code>ALTER TABLE carbon DROP COLUMNS (b1)
-OR
-ALTER TABLE test_db.carbon DROP COLUMNS (b1)
-
-ALTER TABLE carbon DROP COLUMNS (c1,d1)
-</code></pre>
-<p>NOTE: Drop Complex child column is not supported.</p>
-</li>
-<li>
-<p><strong>CHANGE DATA TYPE</strong></p>
-<p>This command is used to change the data type from INT to BIGINT or decimal precision from lower to higher.
-Change of decimal data type from lower precision to higher precision will only be supported for cases where there is no data loss.</p>
-<pre><code>ALTER TABLE [db_name.]table_name CHANGE col_name col_name changed_column_type
-</code></pre>
-<p>Valid Scenarios</p>
-<ul>
-<li>Invalid scenario - Change of decimal precision from (10,2) to (10,5) is invalid as in this case only scale is increased but total number of digits remains the same.</li>
-<li>Valid scenario - Change of decimal precision from (10,2) to (12,3) is valid as the total number of digits are increased by 2 but scale is increased only by 1 which will not lead to any data loss.</li>
-<li>
-<strong>NOTE:</strong> The allowed range is 38,38 (precision, scale) and is a valid upper case scenario which is not resulting in data loss.</li>
-</ul>
-<p>Example1:Changing data type of column a1 from INT to BIGINT.</p>
-<pre><code>ALTER TABLE test_db.carbon CHANGE a1 a1 BIGINT
-</code></pre>
-<p>Example2:Changing decimal precision of column a1 from 10 to 18.</p>
-<pre><code>ALTER TABLE test_db.carbon CHANGE a1 a1 DECIMAL(18,2)
-</code></pre>
-</li>
-<li>
-<p><strong>MERGE INDEX</strong></p>
-<p>This command is used to merge all the CarbonData index files (.carbonindex) inside a segment to a single CarbonData index merge file (.carbonindexmerge). This enhances the first query performance.</p>
-<pre><code> ALTER TABLE [db_name.]table_name COMPACT 'SEGMENT_INDEX'
- ```
-
- Examples:
- ```
- ALTER TABLE test_db.carbon COMPACT 'SEGMENT_INDEX'
- ```
- **NOTE:**
- * Merge index is not supported on streaming table.
-
-</code></pre>
-</li>
-<li>
-<p><strong>SET and UNSET for Local Dictionary Properties</strong></p>
-<p>When set command is used, all the newly set properties will override the corresponding old properties if exists.</p>
-<p>Example to SET Local Dictionary Properties:</p>
-<pre><code>ALTER TABLE tablename SET TBLPROPERTIES('LOCAL_DICTIONARY_ENABLE'='false','LOCAL_DICTIONARY_THRESHOLD'='1000','LOCAL_DICTIONARY_INCLUDE'='column1','LOCAL_DICTIONARY_EXCLUDE'='column2')
-</code></pre>
-<p>When Local Dictionary properties are unset, corresponding default values will be used for these properties.</p>
-<p>Example to UNSET Local Dictionary Properties:</p>
-<pre><code>ALTER TABLE tablename UNSET TBLPROPERTIES('LOCAL_DICTIONARY_ENABLE','LOCAL_DICTIONARY_THRESHOLD','LOCAL_DICTIONARY_INCLUDE','LOCAL_DICTIONARY_EXCLUDE')
-</code></pre>
-<p><strong>NOTE:</strong> For old tables, by default, local dictionary is disabled. If user wants local dictionary for these tables, user can enable/disable local dictionary for new data at their discretion.
-This can be achieved by using the alter table set command.</p>
-</li>
-</ul>
-<h3>
-<a id="drop-table" class="anchor" href="#drop-table" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>DROP TABLE</h3>
-<p>This command is used to delete an existing table.</p>
-<pre><code>DROP TABLE [IF EXISTS] [db_name.]table_name
-</code></pre>
-<p>Example:</p>
-<pre><code>DROP TABLE IF EXISTS productSchema.productSalesTable
-</code></pre>
-<h3>
-<a id="refresh-table" class="anchor" href="#refresh-table" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>REFRESH TABLE</h3>
-<p>This command is used to register Carbon table to HIVE meta store catalogue from existing Carbon table data.</p>
-<pre><code>REFRESH TABLE $db_NAME.$table_NAME
-</code></pre>
-<p>Example:</p>
-<pre><code>REFRESH TABLE dbcarbon.productSalesTable
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>The new database name and the old database name should be same.</li>
-<li>Before executing this command the old table schema and data should be copied into the new database location.</li>
-<li>If the table is aggregate table, then all the aggregate tables should be copied to the new database location.</li>
-<li>For old store, the time zone of the source and destination cluster should be same.</li>
-<li>If old cluster used HIVE meta store to store schema, refresh will not work as schema file does not exist in file system.</li>
-</ul>
-<h3>
-<a id="table-and-column-comment" class="anchor" href="#table-and-column-comment" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Table and Column Comment</h3>
-<p>You can provide more information on table by using table comment. Similarly you can provide more information about a particular column using column comment.
-You can see the column comment of an existing table using describe formatted command.</p>

-<p>This command is used to load csv files to carbondata, OPTIONS are not mandatory for data loading process.
-Inside OPTIONS user can provide any options like DELIMITER, QUOTECHAR, FILEHEADER, ESCAPECHAR, MULTILINE as per requirement.</p>
-<pre><code>LOAD DATA [LOCAL] INPATH 'folder_path'
-INTO TABLE [db_name.]table_name
-OPTIONS(property_name=property_value, ...)
-</code></pre>
-<p>You can use the following options to load data:</p>
-<ul>
-<li>
-<p><strong>DELIMITER:</strong> Delimiters can be provided in the load command.</p>
-<pre><code>OPTIONS('DELIMITER'=',')
-</code></pre>
-</li>
-<li>
-<p><strong>QUOTECHAR:</strong> Quote Characters can be provided in the load command.</p>
-<pre><code>OPTIONS('QUOTECHAR'='"')
-</code></pre>
-</li>
-<li>
-<p><strong>COMMENTCHAR:</strong> Comment Characters can be provided in the load command if user want to comment lines.</p>
-<pre><code>OPTIONS('COMMENTCHAR'='#')
-</code></pre>
-</li>
-<li>
-<p><strong>HEADER:</strong> When you load the CSV file without the file header and the file header is the same with the table schema, then add 'HEADER'='false' to load data SQL as user need not provide the file header. By default the value is 'true'.
-false: CSV file is without file header.
-true: CSV file is with file header.</p>
-<pre><code>OPTIONS('HEADER'='false')
-</code></pre>
-<p><strong>NOTE:</strong> If the HEADER option exist and is set to 'true', then the FILEHEADER option is not required.</p>
-</li>
-<li>
-<p><strong>FILEHEADER:</strong> Headers can be provided in the LOAD DATA command if headers are missing in the source files.</p>
-<pre><code>OPTIONS('FILEHEADER'='column1,column2')
-</code></pre>
-</li>
-<li>
-<p><strong>MULTILINE:</strong> CSV with new line character in quotes.</p>
-<pre><code>OPTIONS('MULTILINE'='true')
-</code></pre>
-</li>
-<li>
-<p><strong>ESCAPECHAR:</strong> Escape char can be provided if user want strict validation of escape character in CSV files.</p>
-<pre><code>OPTIONS('ESCAPECHAR'='\')
-</code></pre>
-</li>
-<li>
-<p><strong>SKIP_EMPTY_LINE:</strong> This option will ignore the empty line in the CSV file during the data load.</p>
-<pre><code>OPTIONS('SKIP_EMPTY_LINE'='TRUE/FALSE')
-</code></pre>
-</li>
-<li>
-<p><strong>COMPLEX_DELIMITER_LEVEL_1:</strong> Split the complex type data column in a row (eg., a$b$c --> Array = {a,b,c}).</p>
-<pre><code>OPTIONS('COMPLEX_DELIMITER_LEVEL_1'='$')
-</code></pre>
-</li>
-<li>
-<p><strong>COMPLEX_DELIMITER_LEVEL_2:</strong> Split the complex type nested data column in a row. Applies level_1 delimiter & applies level_2 based on complex data type (eg., a:b$c:d --> Array> = {{a,b},{c,d}}).</p>
-<pre><code>OPTIONS('COMPLEX_DELIMITER_LEVEL_2'=':')
-</code></pre>
-</li>
-<li>
-<p><strong>ALL_DICTIONARY_PATH:</strong> All dictionary files path.</p>
-<pre><code>OPTIONS('ALL_DICTIONARY_PATH'='/opt/alldictionary/data.dictionary')
-</code></pre>
-</li>
-<li>
-<p><strong>COLUMNDICT:</strong> Dictionary file path for specified column.</p>
-<pre><code>OPTIONS('COLUMNDICT'='column1:dictionaryFilePath1,column2:dictionaryFilePath2')
-</code></pre>
-<p><strong>NOTE:</strong> ALL_DICTIONARY_PATH and COLUMNDICT can't be used together.</p>
-</li>
-<li>
-<p><strong>DATEFORMAT/TIMESTAMPFORMAT:</strong> Date and Timestamp format for specified column.</p>
-<pre><code>OPTIONS('DATEFORMAT' = 'yyyy-MM-dd','TIMESTAMPFORMAT'='yyyy-MM-dd HH:mm:ss')
-</code></pre>
-<p><strong>NOTE:</strong> Date formats are specified by date pattern strings. The date pattern letters in CarbonData are same as in JAVA. Refer to <a href="http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html" target=_blank rel="nofollow">SimpleDateFormat</a>.</p>
-</li>
-<li>
-<p><strong>SORT COLUMN BOUNDS:</strong> Range bounds for sort columns.</p>
-<p>Suppose the table is created with 'SORT_COLUMNS'='name,id' and the range for name is aaa<del>zzz, the value range for id is 0</del>1000. Then during data loading, we can specify the following option to enhance data loading performance.</p>
-<pre><code>OPTIONS('SORT_COLUMN_BOUNDS'='f,250;l,500;r,750')
-</code></pre>
-<p>Each bound is separated by ';' and each field value in bound is separated by ','. In the example above, we provide 3 bounds to distribute records to 4 partitions. The values 'f','l','r' can evenly distribute the records. Inside carbondata, for a record we compare the value of sort columns with that of the bounds and decide which partition the record will be forwarded to.</p>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>SORT_COLUMN_BOUNDS will be used only when the SORT_SCOPE is 'local_sort'.</li>
-<li>Carbondata will use these bounds as ranges to process data concurrently during the final sort percedure. The records will be sorted and written out inside each partition. Since the partition is sorted, all records will be sorted.</li>
-<li>Since the actual order and literal order of the dictionary column are not necessarily the same, we do not recommend you to use this feature if the first sort column is 'dictionary_include'.</li>
-<li>The option works better if your CPU usage during loading is low. If your system is already CPU tense, better not to use this option. Besides, it depends on the user to specify the bounds. If user does not know the exactly bounds to make the data distributed evenly among the bounds, loading performance will still be better than before or at least the same as before.</li>
-<li>Users can find more information about this option in the description of PR1953.</li>
-</ul>
-</li>
-<li>
-<p><strong>SINGLE_PASS:</strong> Single Pass Loading enables single job to finish data loading with dictionary generation on the fly. It enhances performance in the scenarios where the subsequent data loading after initial load involves fewer incremental updates on the dictionary.</p>
-</li>
-</ul>
-<p>This option specifies whether to use single pass for loading data or not. By default this option is set to FALSE.</p>
-<pre><code> OPTIONS('SINGLE_PASS'='TRUE')
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>If this option is set to TRUE then data loading will take less time.</li>
-<li>If this option is set to some invalid value other than TRUE or FALSE then it uses the default value.</li>
-</ul>
-<p>Example:</p>
-<pre><code>LOAD DATA local inpath '/opt/rawdata/data.csv' INTO table carbontable
-options('DELIMITER'=',', 'QUOTECHAR'='"','COMMENTCHAR'='#',
-'HEADER'='false',
-'FILEHEADER'='empno,empname,designation,doj,workgroupcategory,

-'ALL_DICTIONARY_PATH'='/opt/alldictionary/data.dictionary',
-'SINGLE_PASS'='TRUE')
-</code></pre>
-<ul>
-<li>
-<p><strong>BAD RECORDS HANDLING:</strong> Methods of handling bad records are as follows:</p>
-<ul>
-<li>Load all of the data before dealing with the errors.</li>
-<li>Clean or delete bad records before loading data or stop the loading when bad records are found.</li>
-</ul>
-<pre><code>OPTIONS('BAD_RECORDS_LOGGER_ENABLE'='true', 'BAD_RECORD_PATH'='hdfs://hacluster/tmp/carbon', 'BAD_RECORDS_ACTION'='REDIRECT', 'IS_EMPTY_DATA_BAD_RECORD'='false')
-</code></pre>
-</li>
-</ul>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>BAD_RECORDS_ACTION property can have four type of actions for bad records FORCE, REDIRECT, IGNORE and FAIL.</li>
-<li>FAIL option is its Default value. If the FAIL option is used, then data loading fails if any bad records are found.</li>
-<li>If the REDIRECT option is used, CarbonData will add all bad records in to a separate CSV file. However, this file must not be used for subsequent data loading because the content may not exactly match the source record. You are advised to cleanse the original source record for further data ingestion. This option is used to remind you which records are bad records.</li>
-<li>If the FORCE option is used, then it auto-converts the data by storing the bad records as NULL before Loading data.</li>
-<li>If the IGNORE option is used, then bad records are neither loaded nor written to the separate CSV file.</li>
-<li>In loaded data, if all records are bad records, the BAD_RECORDS_ACTION is invalid and the load operation fails.</li>
-<li>The default maximum number of characters per column is 32000. If there are more than 32000 characters in a column, please refer to <em>String longer than 32000 characters</em> section.</li>
-<li>Since Bad Records Path can be specified in create, load and carbon properties.
-Therefore, value specified in load will have the highest priority, and value specified in carbon properties will have the least priority.</li>
-</ul>
-<p><strong>Bad Records Path:</strong></p>
-<p>This property is used to specify the location where bad records would be written.</p>
-<pre><code>TBLPROPERTIES('BAD_RECORDS_PATH'='/opt/badrecords'')
-</code></pre>
-<p>Example:</p>
-<pre><code>LOAD DATA INPATH 'filepath.csv' INTO TABLE tablename
-OPTIONS('BAD_RECORDS_LOGGER_ENABLE'='true','BAD_RECORD_PATH'='hdfs://hacluster/tmp/carbon',
-'BAD_RECORDS_ACTION'='REDIRECT','IS_EMPTY_DATA_BAD_RECORD'='false')
-</code></pre>
-<ul>
-<li>
-<strong>GLOBAL_SORT_PARTITIONS:</strong> If the SORT_SCOPE is defined as GLOBAL_SORT, then user can specify the number of partitions to use while shuffling data for sort using GLOBAL_SORT_PARTITIONS. If it is not configured, or configured less than 1, then it uses the number of map task as reduce task. It is recommended that each reduce task deal with 512MB-1GB data.</li>
-</ul>
-<pre><code>OPTIONS('GLOBAL_SORT_PARTITIONS'='2')
-</code></pre>
-<p>NOTE:</p>
-<ul>
-<li>GLOBAL_SORT_PARTITIONS should be Integer type, the range is [1,Integer.MaxValue].</li>
-<li>It is only used when the SORT_SCOPE is GLOBAL_SORT.</li>
-</ul>

-<p>This command inserts data into a CarbonData table, it is defined as a combination of two queries Insert and Select query respectively.
-It inserts records from a source table into a target CarbonData table, the source table can be a Hive table, Parquet table or a CarbonData table itself.
-It comes with the functionality to aggregate the records of a table by performing Select query on source table and load its corresponding resultant records into a CarbonData table.</p>
-<pre><code>INSERT INTO TABLE <CARBONDATA TABLE> SELECT * FROM sourceTableName
-[ WHERE { <filter_condition> } ]
-</code></pre>
-<p>You can also omit the <code>table</code> keyword and write your query as:</p>
-<pre><code>INSERT INTO <CARBONDATA TABLE> SELECT * FROM sourceTableName
-[ WHERE { <filter_condition> } ]
-</code></pre>
-<p>Overwrite insert data:</p>
-<pre><code>INSERT OVERWRITE TABLE <CARBONDATA TABLE> SELECT * FROM sourceTableName
-[ WHERE { <filter_condition> } ]
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>The source table and the CarbonData table must have the same table schema.</li>
-<li>The data type of source and destination table columns should be same</li>
-<li>INSERT INTO command does not support partial success if bad records are found, it will fail.</li>
-<li>Data cannot be loaded or updated in source table while insert from source table to target table is in progress.</li>
-</ul>
-<p>Examples</p>
-<pre><code>INSERT INTO table1 SELECT item1, sum(item2 + 1000) as result FROM table2 group by item1

-<h3>
-<a id="delete" class="anchor" href="#delete" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>DELETE</h3>
-<p>This command allows us to delete records from CarbonData table.</p>
-<pre><code>DELETE FROM table_name [WHERE expression]
-</code></pre>
-<p>Examples:</p>
-<pre><code>DELETE FROM carbontable WHERE column1 = 'china'
-</code></pre>
-<pre><code>DELETE FROM carbontable WHERE column1 IN ('china', 'USA')
-</code></pre>
-<pre><code>DELETE FROM carbontable WHERE column1 IN (SELECT column11 FROM sourceTable2)

-<a id="compaction" class="anchor" href="#compaction" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>COMPACTION</h2>
-<p>Compaction improves the query performance significantly.</p>
-<p>There are several types of compaction.</p>
-<pre><code>ALTER TABLE [db_name.]table_name COMPACT 'MINOR/MAJOR/CUSTOM'
-</code></pre>
-<ul>
-<li><strong>Minor Compaction</strong></li>
-</ul>
-<p>In Minor compaction, user can specify the number of loads to be merged.
-Minor compaction triggers for every data load if the parameter carbon.enable.auto.load.merge is set to true.
-If any segments are available to be merged, then compaction will run parallel with data load, there are 2 levels in minor compaction:</p>
-<ul>
-<li>Level 1: Merging of the segments which are not yet compacted.</li>
-<li>Level 2: Merging of the compacted segments again to form a larger segment.</li>
-</ul>
-<pre><code>ALTER TABLE table_name COMPACT 'MINOR'
-</code></pre>
-<ul>
-<li><strong>Major Compaction</strong></li>
-</ul>
-<p>In Major compaction, multiple segments can be merged into one large segment.
-User will specify the compaction size until which segments can be merged, Major compaction is usually done during the off-peak time.
-Configure the property carbon.major.compaction.size with appropriate value in MB.</p>
-<p>This command merges the specified number of segments into one segment:</p>
-<pre><code>ALTER TABLE table_name COMPACT 'MAJOR'
-</code></pre>
-<ul>
-<li><strong>Custom Compaction</strong></li>
-</ul>
-<p>In Custom compaction, user can directly specify segment ids to be merged into one large segment.
-All specified segment ids should exist and be valid, otherwise compaction will fail.
-Custom compaction is usually done during the off-peak time.</p>
-<pre><code>ALTER TABLE table_name COMPACT 'CUSTOM' WHERE SEGMENT.ID IN (2,3,4)
-</code></pre>
-<p>NOTE: Compaction is unsupported for table containing Complex columns.</p>
-<ul>
-<li><strong>CLEAN SEGMENTS AFTER Compaction</strong></li>
-</ul>
-<p>Clean the segments which are compacted:</p>
-<pre><code>CLEAN FILES FOR TABLE carbon_table
-</code></pre>

-<h2>
-<a id="bucketing" class="anchor" href="#bucketing" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>BUCKETING</h2>
-<p>Bucketing feature can be used to distribute/organize the table/partition data into multiple files such
-that similar records are present in the same file. While creating a table, user needs to specify the
-columns to be used for bucketing and the number of buckets. For the selection of bucket the Hash value
-of columns is used.</p>
-<pre><code>CREATE TABLE [IF NOT EXISTS] [db_name.]table_name
- [(col_name data_type, ...)]
-STORED BY 'carbondata'
-TBLPROPERTIES('BUCKETNUMBER'='noOfBuckets',
-'BUCKETCOLUMNS'='columnname')
-</code></pre>
-<p><strong>NOTE:</strong></p>
-<ul>
-<li>Bucketing cannot be performed for columns of Complex Data Types.</li>
-<li>Columns in the BUCKETCOLUMN parameter must be dimensions. The BUCKETCOLUMN parameter cannot be a measure or a combination of measures and dimensions.</li>
-</ul>
-<p>Example:</p>
-<pre><code>CREATE TABLE IF NOT EXISTS productSchema.productSalesTable (

-<p>This command is used to list the segments of CarbonData table.</p>
-<pre><code>SHOW [HISTORY] SEGMENTS FOR TABLE [db_name.]table_name LIMIT number_of_segments
-</code></pre>
-<p>Example:
-Show visible segments</p>
-<pre><code>SHOW SEGMENTS FOR TABLE CarbonDatabase.CarbonTable LIMIT 4

-<a id="delete-segment-by-id" class="anchor" href="#delete-segment-by-id" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>DELETE SEGMENT BY ID</h3>
-<p>This command is used to delete segment by using the segment ID. Each segment has a unique segment ID associated with it.
-Using this segment ID, you can remove the segment.</p>
-<p>The following command will get the segmentID.</p>
-<pre><code>SHOW SEGMENTS FOR TABLE [db_name.]table_name LIMIT number_of_segments
-</code></pre>
-<p>After you retrieve the segment ID of the segment that you want to delete, execute the following command to delete the selected segment.</p>
-<pre><code>DELETE FROM TABLE [db_name.]table_name WHERE SEGMENT.ID IN (segment_id1, segments_id2, ...)
-</code></pre>
-<p>Example:</p>
-<pre><code>DELETE FROM TABLE CarbonDatabase.CarbonTable WHERE SEGMENT.ID IN (0)

-<a id="delete-segment-by-date" class="anchor" href="#delete-segment-by-date" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>DELETE SEGMENT BY DATE</h3>
-<p>This command will allow to delete the CarbonData segment(s) from the store based on the date provided by the user in the DML command.
-The segment created before the particular date will be removed from the specific stores.</p>
-<pre><code>DELETE FROM TABLE [db_name.]table_name WHERE SEGMENT.STARTTIME BEFORE DATE_VALUE
-</code></pre>
-<p>Example:</p>
-<pre><code>DELETE FROM TABLE CarbonDatabase.CarbonTable WHERE SEGMENT.STARTTIME BEFORE '2017-06-01 12:05:06'

-<p>This command is used to read data from specified segments during CarbonScan.</p>
-<p>Get the Segment ID:</p>
-<pre><code>SHOW SEGMENTS FOR TABLE [db_name.]table_name LIMIT number_of_segments
-</code></pre>
-<p>Set the segment IDs for table</p>
-<pre><code>SET carbon.input.segments.<database_name>.<table_name> = <list of segment IDs>
-</code></pre>
-<p><strong>NOTE:</strong>
-carbon.input.segments: Specifies the segment IDs to be queried. This property allows you to query specified segments of the specified table. The CarbonScan will read data from specified segments only.</p>
-<p>If user wants to query with segments reading in multi threading mode, then CarbonSession. threadSet can be used instead of SET query.</p>
-<pre><code>CarbonSession.threadSet ("carbon.input.segments.<database_name>.<table_name>","<list of segment IDs>");
-</code></pre>
-<p>Reset the segment IDs</p>
-<pre><code>SET carbon.input.segments.<database_name>.<table_name> = *;
-</code></pre>
-<p>If user wants to query with segments reading in multi threading mode, then CarbonSession. threadSet can be used instead of SET query.</p>
-<pre><code>CarbonSession.threadSet ("carbon.input.segments.<database_name>.<table_name>","*");
-</code></pre>
-<p><strong>Examples:</strong></p>
-<ul>
-<li>Example to show the list of segment IDs,segment status, and other required details and then specify the list of segments to be read.</li>
-</ul>
-<pre><code>SHOW SEGMENTS FOR carbontable1;
-
-SET carbon.input.segments.db.carbontable1 = 1,3,9;

-<p>This tutorial is going to introduce you to the conceptual details of data management like:</p>
-<ul>
-<li><a href="#loading-data">Loading Data</a></li>
-<li><a href="#deleting-data">Deleting Data</a></li>

-<h2>
-<a id="loading-data" class="anchor" href="#loading-data" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Loading Data</h2>
-<ul>
-<li>
-<p><strong>Scenario</strong></p>
-<p>After creating a table, you can load data to the table using the <a href="dml-operation-on-carbondata.html">LOAD DATA</a> command. The loaded data is available for querying.
-When data load is triggered, the data is encoded in CarbonData format and copied into HDFS CarbonData store path (specified in carbon.properties file)
-in compressed, multi dimensional columnar format for quick analysis queries. The same command can be used to load new data or to
-update the existing data. Only one data load can be triggered for one table. The high cardinality columns of the dictionary encoding are
-automatically recognized and these columns will not be used for dictionary encoding.</p>
-</li>
-<li>
-<p><strong>Procedure</strong></p>
-<p>Data loading is a process that involves execution of multiple steps to read, sort and encode the data in CarbonData store format.
-Each step is executed on different threads. After data loading process is complete, the status (success/partial success) is updated to
-CarbonData store metadata. The table below lists the possible load status.</p>
-</li>
-</ul>
-<table>
-<thead>
-<tr>
-<th>Status</th>
-<th>Description</th>
-</tr>
-</thead>
-<tbody>
-<tr>
-<td>Success</td>
-<td>All the data is loaded into table and no bad records found.</td>
-</tr>
-<tr>
-<td>Partial Success</td>
-<td>Data is loaded into table and bad records are found. Bad records are stored at carbon.badrecords.location.</td>
-</tr>
-</tbody>
-</table>
-<p>In case of failure, the error will be logged in error log. Details of loads can be seen with <a href="dml-operation-on-carbondata.html#show-segments">SHOW SEGMENTS</a> command. The show segment command output consists of :</p>
-<ul>
-<li>SegmentSequenceId</li>
-<li>Status</li>
-<li>Load Start Time</li>
-<li>Load End Time</li>
-</ul>
-<p>The latest load will be displayed first in the output.</p>
-<p>Refer to <a href="dml-operation-on-carbondata.html">DML operations on CarbonData</a> for load commands.</p>
-<h2>
-<a id="deleting-data" class="anchor" href="#deleting-data" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Deleting Data</h2>
-<ul>
-<li>
-<p><strong>Scenario</strong></p>
-<p>If you have loaded wrong data into the table, or too many bad records are present and you want to modify and reload the data, you can delete required data loads.
-The load can be deleted using the Segment Sequence Id or if the table contains date field then the data can be deleted using the date field.
-If there are some specific records that need to be deleted based on some filter condition(s) we can delete by records.</p>
-</li>
-<li>
-<p><strong>Procedure</strong></p>
-<p>The loaded data can be deleted in the following ways:</p>
-<ul>
-<li>
-<p>Delete by Segment ID</p>
-<p>After you get the segment ID of the segment that you want to delete, execute the delete command for the selected segment.
-The status of deleted segment is updated to Marked for delete / Marked for Update.</p>
-</li>
-</ul>
-</li>
-</ul>
-<table>
-<thead>
-<tr>
-<th>SegmentSequenceId</th>
-<th>Status</th>
-<th>Load Start Time</th>
-<th>Load End Time</th>

-<td>2015-11-19 20:49:...</td>
-</tr>
-</tbody>
-</table>
-<ul>
-<li>
-<p>Delete by Date Field</p>
-<p>If the table contains date field, you can delete the data based on a specific date.</p>
-</li>
-<li>
-<p>Delete by Record</p>
-<p>To delete records from CarbonData table based on some filter Condition(s).</p>
-<p>For delete commands refer to <a href="dml-operation-on-carbondata.html">DML operations on CarbonData</a>.</p>
-</li>
-<li>
-<p><strong>NOTE</strong>:</p>
-<ul>
-<li>
-<p>When the delete segment DML is called, segment will not be deleted physically from the file system. Instead the segment status will be marked as "Marked for Delete". For the query execution, this deleted segment will be excluded.</p>
-</li>
-<li>
-<p>The deleted segment will be deleted physically during the next load operation and only after the maximum query execution time configured using "max.query.execution.time". By default it is 60 minutes.</p>
-</li>
-<li>
-<p>If the user wants to force delete the segment physically then he can use CLEAN FILES Command.</p>
-</li>
-</ul>
-</li>
-</ul>
-<p>Example :</p>
-<pre><code>CLEAN FILES FOR TABLE table1
-</code></pre>
-<p>This DML will physically delete the segment which are "Marked for delete" and "Compacted" immediately.</p>
-<h2>
-<a id="compacting-data" class="anchor" href="#compacting-data" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Compacting Data</h2>
-<ul>
-<li>
-<p><strong>Scenario</strong></p>
-<p>Frequent data ingestion results in several fragmented CarbonData files in the store directory. Since data is sorted only within each load, the indices perform only within each
-load. This means that there will be one index for each load and as number of data load increases, the number of indices also increases. As each index works only on one load,
-the performance of indices is reduced. CarbonData provides provision for compacting the loads. Compaction process combines several segments into one large segment by merge sorting the data from across the segments.</p>
-</li>
-<li>
-<p><strong>Procedure</strong></p>
-<p>There are two types of compaction Minor and Major compaction.</p>
-<ul>
-<li>
-<p><strong>Minor Compaction</strong></p>
-<p>In minor compaction the user can specify how many loads to be merged. Minor compaction triggers for every data load if the parameter carbon.enable.auto.load.merge is set. If any segments are available to be merged, then compaction will
-run parallel with data load. There are 2 levels in minor compaction.</p>
-<ul>
-<li>Level 1: Merging of the segments which are not yet compacted.</li>
-<li>Level 2: Merging of the compacted segments again to form a bigger segment.</li>
-</ul>
-</li>
-<li>
-<p><strong>Major Compaction</strong></p>
-<p>In Major compaction, many segments can be merged into one big segment. User will specify the compaction size until which segments can be merged. Major compaction is usually done during the off-peak time.</p>
-</li>
-</ul>
-<p>There are number of parameters related to Compaction that can be set in carbon.properties file</p>
-</li>
-</ul>

-<tr>
-<td>carbon.compaction.level.threshold</td>
-<td>4, 3</td>
-<td>Minor</td>
-<td>This property is for minor compaction which decides how many segments to be merged. Example: If it is set as "2, 3", then minor compaction will be triggered for every 2 segments in level 1. 3 is the number of level 1 compacted segment which is further compacted to new segment in level 2.</td>

-</tr>
-<tr>
-<td>carbon.allowed.compaction.days</td>
-<td>0</td>
-<td>Minor/Major</td>
-<td>Compaction will merge the segments which are loaded within the specific number of days configured. Example: If the configuration is 2, then the segments which are loaded in the time frame of 2 days only will get merged. Segments which are loaded 2 days apart will not be merged. This is disabled by default.</td>

-<a id="updating-data" class="anchor" href="#updating-data" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Updating Data</h2>
-<ul>
-<li>
-<p><strong>Scenario</strong></p>
-<p>Sometimes after the data has been ingested into the System, it is required to be updated. Also there may be situations where some specific columns need to be updated
-on the basis of column expression and optional filter conditions.</p>
-</li>
-<li>
-<p><strong>Procedure</strong></p>
-<p>To update we need to specify the column expression with an optional filter condition(s).</p>

-<a id="usage-guidelines" class="anchor" href="#usage-guidelines" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Usage Guidelines</h3>
-<p>Following are the guidelines for using table properties.</p>
-<ul>
-<li>
-<p><strong>Dictionary Encoding Configuration</strong></p>
-<p>Dictionary encoding is enabled by default for all String columns, and disabled for non-String columns. You can include and exclude columns for dictionary encoding.</p>
-</li>
-</ul>
-<pre><code> TBLPROPERTIES ('DICTIONARY_EXCLUDE'='column1, column2')
- TBLPROPERTIES ('DICTIONARY_INCLUDE'='column1, column2')
-</code></pre>
-<p>Here, DICTIONARY_EXCLUDE will exclude dictionary creation. This is applicable for high-cardinality columns and is an optional parameter. DICTIONARY_INCLUDE will generate dictionary for the columns specified in the list.</p>
-<ul>
-<li>
-<p><strong>Table Block Size Configuration</strong></p>
-<p>The block size of table files can be defined using the property TABLE_BLOCKSIZE. It accepts only integer values. The default value is 1024 MB and supports a range of 1 MB to 2048 MB.
-If you do not specify this value in the DDL command, default value is used.</p>
-</li>
-</ul>
-<pre><code> TBLPROPERTIES ('TABLE_BLOCKSIZE'='512')
-</code></pre>
-<p>Here 512 MB means the block size of this table is 512 MB, you can also set it as 512M or 512.</p>
-<ul>
-<li>
-<p><strong>Inverted Index Configuration</strong></p>
-<p>Inverted index is very useful to improve compression ratio and query speed, especially for those low-cardinality columns which are in reward position.
-By default inverted index is enabled. The user can disable the inverted index creation for some columns.</p>
-</li>
-</ul>
-<pre><code> TBLPROPERTIES ('NO_INVERTED_INDEX'='column1, column3')
-</code></pre>
-<p>No inverted index shall be generated for the columns specified in NO_INVERTED_INDEX. This property is applicable on columns with high-cardinality and is an optional parameter.</p>
-<p>NOTE:</p>
-<ul>
-<li>
-<p>By default all columns other than numeric datatype are treated as dimensions and all columns of numeric datatype are treated as measures.</p>
-</li>
-<li>
-<p>All dimensions except complex datatype columns are part of multi dimensional key(MDK). This behavior can be overridden by using TBLPROPERTIES. If the user wants to keep any column (except columns of complex datatype) in multi dimensional key then he can keep the columns either in DICTIONARY_EXCLUDE or DICTIONARY_INCLUDE.</p>
-</li>
-<li>
-<p><strong>Sort Columns Configuration</strong></p>
-<p>"SORT_COLUMN" property is for users to specify which columns belong to the MDK index. If user don't specify "SORT_COLUMN" property, by default MDK index be built by using all dimension columns except complex datatype column.</p>
-</li>
-</ul>
-<pre><code> TBLPROPERTIES ('SORT_COLUMNS'='column1, column3')
-</code></pre>
-<h3>
-<a id="example" class="anchor" href="#example" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Example:</h3>

- revenue Int)
- STORED BY 'carbondata'
- TBLPROPERTIES ('DICTIONARY_EXCLUDE'='storeCity',
- 'DICTIONARY_INCLUDE'='productNumber',
- 'NO_INVERTED_INDEX'='productBatch',
- 'SORT_COLUMNS'='productName,storeCity')
-</code></pre>
-<ul>
-<li><strong>SORT_COLUMNS</strong></li>
-</ul>
-<pre><code>This table property specifies the order of the sort column.
-</code></pre>
-<pre><code> TBLPROPERTIES('SORT_COLUMNS'='column1, column3')
-</code></pre>
-<p>NOTE:</p>
-<ul>
-<li>
-<p>If this property is not specified, then by default SORT_COLUMNS consist of all dimension (exclude Complex Column).</p>
-</li>
-<li>
-<p>If this property is specified but with empty argument, then the table will be loaded without sort. For example, ('SORT_COLUMNS'='')</p>

-<a id="usage-guidelines" class="anchor" href="#usage-guidelines" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Usage Guidelines</h3>
-<p>You can use the following options to load data:</p>
-<ul>
-<li>
-<p><strong>DELIMITER:</strong> Delimiters can be provided in the load command.</p>
-<pre><code>OPTIONS('DELIMITER'=',')
-</code></pre>
-</li>
-<li>
-<p><strong>QUOTECHAR:</strong> Quote Characters can be provided in the load command.</p>
-<pre><code>OPTIONS('QUOTECHAR'='"')
-</code></pre>
-</li>
-<li>
-<p><strong>COMMENTCHAR:</strong> Comment Characters can be provided in the load command if user want to comment lines.</p>
-<pre><code>OPTIONS('COMMENTCHAR'='#')
-</code></pre>
-</li>
-<li>
-<p><strong>FILEHEADER:</strong> Headers can be provided in the LOAD DATA command if headers are missing in the source files.</p>
-<pre><code>OPTIONS('FILEHEADER'='column1,column2')
-</code></pre>
-</li>
-<li>
-<p><strong>MULTILINE:</strong> CSV with new line character in quotes.</p>
-<pre><code>OPTIONS('MULTILINE'='true')
-</code></pre>
-</li>
-<li>
-<p><strong>ESCAPECHAR:</strong> Escape char can be provided if user want strict validation of escape character on CSV.</p>
-<pre><code>OPTIONS('ESCAPECHAR'='\')
-</code></pre>
-</li>
-<li>
-<p><strong>COMPLEX_DELIMITER_LEVEL_1:</strong> Split the complex type data column in a row (eg., a$b$c --> Array = {a,b,c}).</p>
-<pre><code>OPTIONS('COMPLEX_DELIMITER_LEVEL_1'='$')
-</code></pre>
-</li>
-<li>
-<p><strong>COMPLEX_DELIMITER_LEVEL_2:</strong> Split the complex type nested data column in a row. Applies level_1 delimiter & applies level_2 based on complex data type (eg., a:b$c:d --> Array> = {{a,b},{c,d}}).</p>
-<pre><code>OPTIONS('COMPLEX_DELIMITER_LEVEL_2'=':')
-</code></pre>
-</li>
-<li>
-<p><strong>ALL_DICTIONARY_PATH:</strong> All dictionary files path.</p>
-<pre><code>OPTIONS('ALL_DICTIONARY_PATH'='/opt/alldictionary/data.dictionary')
-</code></pre>
-</li>
-<li>
-<p><strong>COLUMNDICT:</strong> Dictionary file path for specified column.</p>
-<pre><code>OPTIONS('COLUMNDICT'='column1:dictionaryFilePath1,
-column2:dictionaryFilePath2')
-</code></pre>
-<p>NOTE: ALL_DICTIONARY_PATH and COLUMNDICT can't be used together.</p>
-</li>
-<li>
-<p><strong>DATEFORMAT:</strong> Date format for specified column.</p>
-<pre><code>OPTIONS('DATEFORMAT'='column1:dateFormat1, column2:dateFormat2')
-</code></pre>
-<p>NOTE: Date formats are specified by date pattern strings. The date pattern letters in CarbonData are same as in JAVA. Refer to <a href="http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html" target=_blank>SimpleDateFormat</a>.</p>
-</li>
-<li>
-<p><strong>SINGLE_PASS:</strong> Single Pass Loading enables single job to finish data loading with dictionary generation on the fly. It enhances performance in the scenarios where the subsequent data loading after initial load involves fewer incremental updates on the dictionary.</p>
-<p>This option specifies whether to use single pass for loading data or not. By default this option is set to FALSE.</p>
-<pre><code>OPTIONS('SINGLE_PASS'='TRUE')
-</code></pre>
-<p>Note :</p>
-<ul>
-<li>
-<p>If this option is set to TRUE then data loading will take less time.</p>
-</li>
-<li>
-<p>If this option is set to some invalid value other than TRUE or FALSE then it uses the default value.</p>
-</li>
-<li>
-<p>If this option is set to TRUE, then high.cardinality.identify.enable property will be disabled during data load.</p>
-</li>

-<p><strong>BAD RECORDS HANDLING:</strong> Methods of handling bad records are as follows:</p>
-<ul>
-<li>
-<p>Load all of the data before dealing with the errors.</p>
-</li>
-<li>
-<p>Clean or delete bad records before loading data or stop the loading when bad records are found.</p>
-</li>
-</ul>
-<pre><code>OPTIONS('BAD_RECORDS_LOGGER_ENABLE'='true', 'BAD_RECORD_PATH'='hdfs://hacluster/tmp/carbon', 'BAD_RECORDS_ACTION'='REDIRECT', 'IS_EMPTY_DATA_BAD_RECORD'='false')
-</code></pre>
-<p>NOTE:</p>
-<ul>
-<li>
-<p>If the REDIRECT option is used, Carbon will add all bad records in to a separate CSV file. However, this file must not be used for subsequent data loading because the content may not exactly match the source record. You are advised to cleanse the original source record for further data ingestion. This option is used to remind you which records are bad records.</p>
-</li>
-<li>
-<p>In loaded data, if all records are bad records, the BAD_RECORDS_ACTION is invalid and the load operation fails.</p>
-</li>
-<li>
-<p>The maximum number of characters per column is 100000. If there are more than 100000 characters in a column, data loading will fail.</p>

-<p>This command inserts data into a CarbonData table. It is defined as a combination of two queries Insert and Select query respectively. It inserts records from a source table into a target CarbonData table. The source table can be a Hive table, Parquet table or a CarbonData table itself. It comes with the functionality to aggregate the records of a table by performing Select query on source table and load its corresponding resultant records into a CarbonData table.</p>
-<p><strong>NOTE</strong> : The client node where the INSERT command is executing, must be part of the cluster.</p>

-<p>The following condition must be met for successful insert operation :</p>
-<ul>
-<li>The source table and the CarbonData table must have the same table schema.</li>
-<li>The table must be created.</li>
-<li>Overwrite is not supported for CarbonData table.</li>
-<li>The data type of source and destination table columns should be same, else the data from source table will be treated as bad records and the INSERT command fails.</li>
-<li>INSERT INTO command does not support partial success if bad records are found, it will fail.</li>
-<li>Data cannot be loaded or updated in source table while insert from source table to target table is in progress.</li>
-</ul>
-<p>To enable data load or update during insert operation, configure the following property to true.</p>
-<pre><code>carbon.insert.persist.enable=true
-</code></pre>
-<p>By default the above configuration will be false.</p>

-<a id="usage-guidelines-2" class="anchor" href="#usage-guidelines-2" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Usage Guidelines</h3>
-<p>The following conditions must be met for successful updation :</p>
-<ul>
-<li>The update command fails if multiple input rows in source table are matched with single row in destination table.</li>
-<li>If the source table generates empty records, the update operation will complete successfully without updating the table.</li>
-<li>If a source table row does not correspond to any of the existing rows in a destination table, the update operation will complete successfully without updating the table.</li>
-<li>In sub-query, if the source table and the target table are same, then the update operation fails.</li>
-<li>If the sub-query used in UPDATE statement contains aggregate method or group by query, then the UPDATE operation fails.</li>
-</ul>
-<h3>
-<a id="examples-1" class="anchor" href="#examples-1" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Examples</h3>
-<p>Update is not supported for queries that contain aggregate or group by.</p>
-<pre><code> UPDATE t_carbn01 a
- SET (a.item_type_code, a.profit) = ( SELECT b.item_type_cd,
- sum(b.profit) from t_carbn01b b
- WHERE item_type_cd =2 group by item_type_code);
-</code></pre>
-<p>Here the Update Operation fails as the query contains aggregate function sum(b.profit) and group by clause in the sub-query.</p>
-<pre><code>UPDATE carbonTable1 d
-SET(d.column3,d.column5 ) = (SELECT s.c33 ,s.c55
-FROM sourceTable1 s WHERE d.column1 = s.c11)

-<p><a href="https://github.com/apache/carbondata/blob/master/build/README.md" target=_blank>Build the CarbonData</a> project and get the assembly jar from <code>./assembly/target/scala-2.1x/carbondata_xxx.jar</code>.</p>
-</li>
-<li>
-<p>Copy <code>./assembly/target/scala-2.1x/carbondata_xxx.jar</code> to <code>$SPARK_HOME/carbonlib</code> folder.</p>
-<p><strong>NOTE</strong>: Create the carbonlib folder if it does not exist inside <code>$SPARK_HOME</code> path.</p>
-</li>
-<li>
-<p>Add the carbonlib folder path in the Spark classpath. (Edit <code>$SPARK_HOME/conf/spark-env.sh</code> file and modify the value of <code>SPARK_CLASSPATH</code> by appending <code>$SPARK_HOME/carbonlib/*</code> to the existing value)</p>
-</li>
-<li>
-<p>Copy the <code>./conf/carbon.properties.template</code> file from CarbonData repository to <code>$SPARK_HOME/conf/</code> folder and rename the file to <code>carbon.properties</code>.</p>
-</li>
-<li>
-<p>Repeat Step 2 to Step 5 in all the nodes of the cluster.</p>
-</li>
-<li>
-<p>In Spark node[master], configure the properties mentioned in the following table in <code>$SPARK_HOME/conf/spark-defaults.conf</code> file.</p>

-<p><strong>NOTE</strong>: From Spark 1.6, by default the Thrift server runs in multi-session mode. Which means each JDBC/ODBC connection owns a copy of their own SQL configuration and temporary function registry. Cached tables are still shared though. If you prefer to run the Thrift server in single-session mode and share all SQL configuration and temporary function registry, please set option <code>spark.sql.hive.thriftServer.singleSession</code> to <code>true</code>. You may either add this option to <code>spark-defaults.conf</code>, or pass it to <code>spark-submit.sh</code> via <code>--conf</code>:</p>
-<pre><code>./bin/spark-submit
---conf spark.sql.hive.thriftServer.singleSession=true
---class org.apache.carbondata.spark.thriftserver.CarbonThriftServer
-$SPARK_HOME/carbonlib/$CARBON_ASSEMBLY_JAR <carbon_store_path>
-</code></pre>
-<p><strong>But</strong> in single-session mode, if one user changes the database from one connection, the database of the other connections will be changed too.</p>
-<p><strong>Examples</strong></p>
-<ul>
-<li>Start with default memory and executors.</li>

-</code></pre>
-<p><strong>Note:</strong></p>
-<ul>
-<li>
-<p>The 'RANGE_INFO' must be defined in ascending order in the table properties.</p>
-</li>
-<li>
-<p>The default format for partition column of Date/Timestamp type is yyyy-MM-dd. Alternate formats for Date/Timestamp could be defined in CarbonProperties.</p>
-</li>

-<a id="drop-a-partition" class="anchor" href="#drop-a-partition" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Drop a partition</h3>
-<pre><code> //Drop partition definition only and keep data
- ALTER TABLE [db_name].table_name DROP PARTITION(partition_id)
-
- //Drop both partition definition and data
- ALTER TABLE [db_name].table_name DROP PARTITION(partition_id) WITH DATA
-</code></pre>
-<p><strong>Note</strong>:</p>
-<ul>
-<li>
-<p>In the first case where the data in the table is preserved there can be multiple scenarios as described below :</p>
-<ul>
-<li>
-<p>if the table is a range partition table, data will be merged into the next partition, and if the dropped partition is the last partition, then data will be merged into the default partition.</p>
-</li>
-<li>
-<p>if the table is a list partition table, data will be merged into default partition.</p>
-</li>
-</ul>
-</li>
-<li>
-<p>Dropping the default partition is not allowed, but DELETE statement can be used to delete data in default partition.</p>
-</li>
-<li>
-<p>The partition_id could be fetched using the <a href="#show-partitions">SHOW PARTITIONS</a> command.</p>
-</li>
-<li>
-<p>Hash partition table is not supported for ADD, SPLIT and DROP commands.</p>
-</li>
-</ul>
-<h2>
-<a id="partition-id" class="anchor" href="#partition-id" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Partition Id</h2>
-<p>In CarbonData like the hive, folders are not used to divide partitions instead partition id is used to replace the task id. It could make use of the characteristic and meanwhile reduce some metadata.</p>
-<pre><code>SegmentDir/0_batchno0-0-1502703086921.carbonindex
- ^
-SegmentDir/part-0-0_batchno0-0-1502703086921.carbondata
- ^
-</code></pre>
-<h2>
-<a id="useful-tips" class="anchor" href="#useful-tips" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>Useful Tips</h2>
-<p>Here are some useful tips to improve query performance of carbonData partition table:</p>
-<p><strong>Prior analysis of proper partition column</strong></p>
-<p>The distribution of data based on some random column could be skewed, building a skewed partition table is meaningless. Some basic statistical analysis before the creation of partition table can avoid an extremely skewed column.</p>
-<p><strong>Exclude partition column from sort columns</strong></p>
-<p>If you have many dimensions, that need to be sorted then one must exclude column present in the partition from sort columns, this will allow another dimension to do the efficient sorting.</p>
-<p><strong>Remember to add filter on partition column when writing SQL</strong></p>
-<p>When writing SQL on a partition table, try to use filters on the partition column.</p>

-<p>In the carbon jars package, there exist a carbondata-store-sdk-x.x.x-SNAPSHOT.jar.
-This SDK writer, writes carbondata file and carbonindex file at a given path.
-External client can make use of this writer to convert other format data or live data to create carbondata and index files.
-These SDK writer output contains just a carbondata and carbonindex files. No metadata folder will be present.</p>
