+
+ <p>Partition pruning is a performance optimization that limits the number of files and partitions that Drill reads when querying file systems and Hive tables. When you partition data, Drill only reads a subset of the files that reside in a file system or a subset of the partitions in a Hive table when a query matches certain filter criteria.</p>
+
+<p>The query planner in Drill performs partition pruning by evaluating the filters. If no partition filters are present, the underlying Scan operator reads all files in all directories and then sends the data to operators, such as Filter, downstream. When partition filters are present, the query planner pushes the filters down to the Scan if possible. The Scan reads only the directories that match the partition filters, thus reducing disk I/O.</p>

+
+<p>Before using partitioned Drill 1.1-1.2 data in Drill 1.3, you need to migrate the data. Migrate Parquet data as described in <a href="/docs/migrating-partitioned-data/">"Migrating Partitioned Data"</a>. </p>

-<h2 id="migrating-partitioned-data-from-drill-1-1-1-2-to-drill-1-3">Migrating Partitioned Data from Drill 1.1-1.2 to Drill 1.3</h2>
-
-<p>Use the <a href="https://github.com/parthchandra/drill-upgrade">drill-upgrade tool</a> to migrate Parquet data that you generated in Drill 1.1 or 1.2 before attempting to use the data with Drill 1.3 partition pruning. This migration is mandatory because Parquet data generated by Drill 1.1 and 1.2 must be marked as Drill-generated, as described in <a href="https://issues.apache.org/jira/browse/DRILL-4070">DRILL-4070</a>. </p>
-
-<p>Drill 1.3 fixes a bug to accurately process Parquet files produced by other tools, such as Pig and Hive. The bug fix eliminated the risk of inaccurate metadata that could cause incorrect results when querying Hive- and Pig-generated Parquet files. No such risk exists with Drill-generated Parquet files. Querying Drill-generated Parquet files, regardless of the Drill version, yields accurate results. Drill-generated Parquet files, regardless of the Drill release, contain accurate metadata.</p>
-
-<p>After using the drill-upgrade tool to migrate your partitioned, pre-1.3 Parquet data, Drill can distinguish these files from those generated by other tools, such as Hive and Pig. Use the migration tool only on files generated by Drill. </p>
-
-<p>To partition and query Parquet files generated from other tools, use Drill to read and rewrite the files and metadata using the CTAS command with the PARTITION BY clause. Alternatively, use the tool that generated the original files to regenerate Parquet 1.8 or later files.</p>
-
-<h2 id="how-to-partition-data">How to Partition Data</h2>
-
-<p>In Drill 1.1.0 and later, if the data source is Parquet, no data organization tasks are required to take advantage of partition pruning. Write Parquet data using the <a href="/docs/partition-by-clause/">PARTITION BY</a> clause in the CTAS statement. </p>
-
-<p>The Parquet writer first sorts data by the partition keys, and then creates a new file when it encounters a new value for the partition columns. During partitioning, Drill creates separate files, but not separate directories, for different partitions. Each file contains exactly one partition value, but there can be multiple files for the same partition value. </p>
-
-<p>Partition pruning uses the Parquet column statistics to determine which columns to use to prune. </p>
-
-<p>Unlike using the Drill 1.0 partitioning, no view query is subsequently required, nor is it necessary to use the <a href="/docs/querying-directories">dir* variables</a> after you use the Drill 1.1 PARTITION BY clause in a CTAS statement. </p>
-
-<h2 id="drill-1-0-partitioning">Drill 1.0 Partitioning</h2>
-
-<p>You perform the following steps to partition data in Drill 1.0. </p>
-
-<ol>
-<li>Devise a logical way to store the data in a hierarchy of directories. </li>
-<li>Use CTAS to create Parquet files from the original data, specifying filter conditions.</li>
-<li>Move the files into directories in the hierarchy. </li>
-</ol>
-
-<p>After partitioning the data, you need to create a view of the partitioned data to query the data. You can use the <a href="/docs/querying-directories">dir* variables</a> in queries to refer to subdirectories in your workspace path.</p>
-
-<h3 id="drill-1-0-partitioning-example">Drill 1.0 Partitioning Example</h3>
-
-<p>Suppose you have text files containing several years of log data. To partition the data by year and quarter, create the following hierarchy of directories: </p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> …/logs/1994/Q1
- …/logs/1994/Q2
- …/logs/1994/Q3
- …/logs/1994/Q4
- …/logs/1995/Q1
- …/logs/1995/Q2
- …/logs/1995/Q3
- …/logs/1995/Q4
- …/logs/1996/Q1
- …/logs/1996/Q2
- …/logs/1996/Q3
- …/logs/1996/Q4
-</code></pre></div>
-<p>Run the following CTAS statement, filtering on the Q1 1994 data.</p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> CREATE TABLE TT_1994_Q1
- AS SELECT * FROM <raw table data in text format >
- WHERE columns[1] = 1994 AND columns[2] = 'Q1'
-</code></pre></div>
-<p>This creates a Parquet file with the log data for Q1 1994 in the current workspace. You can then move the file into the correlating directory, and repeat the process until all of the files are stored in their respective directories.</p>
-
-<p>Now you can define views on the parquet files and query the views. </p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> 0: jdbc:drill:zk=local> create view vv1 as select `dir0` as `year`, `dir1` as `qtr` from dfs.`/Users/max/data/multilevel/parquet`;

-<p>Query the view to see all of the logs. </p>
-<div class="highlight"><pre><code class="language-text" data-lang="text"> 0: jdbc:drill:zk=local> select * from dfs.tmp.vv1;
