The values are set based on their matching position between the source and target tables. The list of columns is optional and if not present will map to the column in the order they are declared in the schema. If auto commit is on, and both a) the target table matches the source table, and b) the select performs no aggregation, then the population of the target table will be done completely on the server-side (with constraint violations logged, but otherwise ignored). Otherwise, data is buffered on the client and, if auto commit is on, committed in row batches as specified by the UpsertBatchSize connection property (or the phoenix.mutate.upsertBatchSize <code>HBase</code> config property which defaults to 10000 rows)</p>

+<p>Creates a new table. The <code>HBase</code> table and any column families referenced are created if they don't already exist. All table, column family and column names are uppercased unless they are double quoted in which case they are case sensitive. Column families that exist in the <code>HBase</code> table but are not listed are ignored. At create time, to improve query performance, an empty key value is added to the first column family of any existing rows or the default column family if no column families are explicitly defined. Upserts will also add this empty key value. This improves query performance by having a key value column we can guarantee always being there and thus minimizing the amount of data that must be projected and subsequently returned back to the client. <code>HBase</code> table and column configuration options may be passed through as key/value pairs to configure the <code>HBase</code> table as desired. Note that when using the <code>IF NOT EXISTS</co
de> clause, if a table already exists, then no change will be made to it. Additionally, no validation is done to check whether the existing table metadata matches the proposed table metadata. so it's better to use <code>DROP TABLE</code> followed by <code>CREATE TABLE</code> is the table metadata may be changing.</p>

+<p>Creates a new view over an existing <code>HBase</code> or Phoenix table. As expected, the <code>WHERE</code> expression is always automatically applied to any query run against the view. As with <code>CREATE TABLE</code>, the table, column family, and column names are uppercased unless they are double quoted. The newTableRef may refer directly to an <code>HBase</code> table, in which case, the table, column family, and column names must match the existing metadata exactly or an exception will occur. When a view is mapped directly to an <code>HBase</code> table, no empty key value will be added to rows and the view will be read-only. A view will be updatable (i.e. referenceable in a <code>DML</code> statement such as <code>UPSERT</code> or <code>DELETE</code>) if its <code>WHERE</code> clause expression contains only simple equality expressions separated by <code>ANDs</code>. Updatable views are not required to set the columns which appear in the equality expressions, as the equal
ity expressions define the default values for those columns. If they are set, then they must match the value used in the <code>WHERE</code> clause, or an error will occur. All columns from the existingTableRef are included as columns in the new view as are columns defined in the columnDef list. An <code>ALTER VIEW</code> statement may be issued against a view to remove or add columns, however, no changes may be made to the primary key constraint. In addition, columns referenced in the <code>WHERE</code> clause are not allowed to be removed. Once a view is created for a table, that table may no longer altered or dropped until all of its views have been dropped.</p>

+<p>Creates a new secondary index on a table or view. The index will be automatically kept in sync with the table as the data changes. At query time, the optimizer will use the index if it contains all columns referenced in the query and produces the most efficient execution plan. If a table has rows that are write-once and append-only, then the table may set the <code>IMMUTABLE_ROWS</code> property to true (either up-front in the <code>CREATE TABLE</code> statement or afterwards in an <code>ALTER TABLE</code> statement). This reduces the overhead at write time to maintain the index. Otherwise, if this property is not set on the table, then incremental index maintenance will be performed on the server side when the data changes. As of the 4.3 release, functional indexes are supported which allow arbitrary expressions rather than solely column names to be indexed.</p>

+<p class="notranslate">

+<p>Sets a built-in Phoenix table property or an <code>HBase</code> table or column descriptor metadata attribute. The name is case insensitive. Built-in Phoenix table options include <code>SALT_BUCKETS, DISABLE_WAL, IMMUTABLE_ROWS, MULTI_TENANT, DEFAULT_COLUMN_FAMILY</code>, and <code>STORE_NULLS</code>. If the name is a known <code>HColumnDescriptor</code> attribute, then the value is applied to the specified column family or, if omitted, to all column families. Otherwise, the <code>HBase</code> metadata attribute value is applied to the <code>HTableDescriptor</code>. Note that no validation is performed on the property name or value, so unknown or misspelled options will end up as adhoc metadata attributes values on the <code>HBase</code> table.</p><p>The <code>SALT_BUCKETS</code> numeric property causes an extra byte to be transparently prepended to every row key to ensure an evenly distributed read and write load across all region servers. This is especially useful when your row
key is always monotonically increasing and causing hot spotting on a single region server. However, even if it's not, it often improves performance by ensuring an even distribution of data across your cluster. The byte is determined by hashing the row key and modding it with the <code>SALT_BUCKETS</code> value. The value may be from 0 to 256, with 0 being a special means of turning salting off for an index in which the data table is salted (since by default an index has the same number of salt buckets as its data table). If split points are not defined for the table, the table will automatically be pre-split at each possible salt bucket value. For more information, see http://phoenix.incubator.apache.org/salted.html</p><p>The <code>DISABLE_WAL</code> boolean option when true causes <code>HBase</code> not to write data to the write-ahead-log, thus making updates faster at the expense of potentially losing data in the event of a region server failure. This option is useful
when updating a table which is not the source-of-truth and thus making the lose of data acceptable.</p><p>The <code>IMMUTABLE_ROWS</code> boolean option when true declares that your table has rows which are write-once, append-only (i.e. the same row is never updated or deleted). With this option set, indexes added to the table are managed completely on the client-side, with no need to perform incremental index maintenance., thus improving performance. Deletes are not allowed (beyond dropping the entire table) and updates are expected to never update an existing row (failure to follow this will result in invalid indexes). For more information, see http://phoenix.incubator.apache.org/secondary_indexing.html</p><p>The <code>MULTI_TENANT</code> boolean option when true enables views to be created over the table across different tenants. This option is useful to share the same physical <code>HBase</code> table across many different tenants. For more information, see http://phoenix.incuba
tor.apache.org/multi-tenancy.html</p><p>The <code>DEFAULT_COLUMN_FAMILY</code> string option determines the column family used used when none is specified. The value is case sensitive. If this option is not present, a column family name of '0' is used.</p><p>The <code>STORE_NULLS</code> boolean option (available as of Phoenix 4.3) determines whether or not null values should be explicitly stored in <code>HBase</code>. This option is generally only useful if a table is configured to store multiple versions in order to facilitate doing flashback queries (i.e. queries to look at the state of a record in the past).</p>
+<p>Example:</p>
+<p class="notranslate">IMMUTABLE_ROWS=true<br />DEFAULT_COLUMN_FAMILY='a'<br />SALT_BUCKETS=10<br />DATA_BLOCK_ENCODING='NONE',a.VERSIONS=10<br />MAX_FILESIZE=2000000000,MEMSTORE_FLUSHSIZE=80000000</p>

+<p>Use the <code>SKIP_SCAN</code> hint to force a skip scan to be performed on the query when it otherwise would not be. This option may improve performance if a query does not include the leading primary key column, but does include other, very selective primary key columns.</p><p>Use the <code>RANGE_SCAN</code> hint to force a range scan to be performed on the query. This option may improve performance if a query filters on a range for non selective leading primary key column along with other primary key columns</p>

+<p>Use the <code>INDEX</code>(<table_name> <index_name>...) to suggest which index to use for a given query. Double quotes may be used to surround a table_name and/or index_name to make them case sensitive. As of the 4.3 release, this will force an index to be used, even if it doesn't contain all referenced columns, by joining back to the data table to retrieve any columns not contained by the index.</p><p>Use the <code>NO_INDEX</code> hint to force the data table to be used for a query.</p><p>Use the <code>USE_INDEX_OVER_DATA_TABLE</code> hint to act as a tiebreaker for choosing the index table over the data table when all other criteria are equal. Note that this is the default optimizer decision.</p><p>Use the <code>USE_DATA_OVER_INDEX_TABLE</code> hint to act as a tiebreaker for choosing the data table over the index table when all other criteria are equal.</p>

+<p>Use the <code>SMALL</code> hint to reduce the number of <code>RPCs</code> done between the client and server when a query is executed. Generally, if the query is a point lookup or returns data that is likely in a single data block (64 KB by default), performance may improve when using this hint.</p>

This is useful when the results of the querying the one common table is too large and would likely be substantially filtered when joined against one or more of the other joined tables.</p>
