+ scratch directories in a round robin fashion. Automatic selection of scratch directories in
+ a round robin fashion may not always be ideal in every situation since these directories
+ could come from different classes of storage system volumes having different performance
+ characteristics (SSD vs HDD, local storage vs network attached storage, etc.). To optimize
+ your workload, you have an option to configure the priority of the scratch directories based
+ on your storage system configuration.</p>
+
+ <p class="p">The scratch directories will be selected for spilling based on how you configure the
+ priorities of the directories and if you provide the same priority for multiple directories
+ then the directories will be selected in a round robin fashion.</p>

+ <div class="p">The valid formats for specifying the priority directories are as shown here:
+ <pre class="pre codeblock"><code>

+ <dir-path>::<priority>

+
+ Impala now supports Apache Iceberg which is an open table format for huge analytic datasets.
+ With this functionality, you can access any existing Iceberg tables using SQL and perform
+ analytics over them. Using Impala you can create and write Iceberg tables in different
+ Iceberg Catalogs (e.g. HiveCatalog, HadoopCatalog). It also supports location-based
+ tables (HadoopTables).
+ </p>
+
+ <p class="p">
+ Currently only Iceberg V1 DML operations are allowed, i.e. INSERT INTO /INSERT OVERWRITE.
+ Iceberg V2 operations like row-level modifications (UPDATE, DELETE) are not supported yet.
+ </p>
+
+
+ <p class="p">
+ For more information on Iceberg, see <a class="xref" href="https://iceberg.apache.org" target="_blank">the Apache Iceberg site</a>.

+ ACID compliance: DML operations are atomic, queries always read a consistent snapshot.

+ Hidden partitioning: Iceberg produces partition values by taking a column value and
+ optionally transforming it. Partition information is stored in the Iceberg metadata
+ files. Iceberg is able to TRUNCATE column values or calculate
+ a hash of them and use it for partitioning. Readers don't need to be aware of the
+ partitioning of the table.
+ </li>
+
+ <li class="li">
+ Partition layout evolution: When the data volume or the query patterns change you
+ can update the layout of a table. Since hidden partitioning is used, you don't need to
+ rewrite the data files during partition layout evolution.

+
+ <li class="li">
+ Schema evolution: supports add, drop, update, or rename schema elements,
+ and has no side-effects.
+ </li>
+

+ snapshot, or lets users easily examine changes.

+
+ <div class="body conbody">
+ <p class="p">
+ When you have an existing Iceberg table that is not yet present in the Hive Metastore,
+ you can use the <code class="ph codeph">CREATE EXTERNAL TABLE</code> command in Impala to add the table to the Hive
+ Metastore and make Impala able to interact with this table. Currently Impala supports
+ HadoopTables, HadoopCatalog, and HiveCatalog. If you have an existing table in HiveCatalog,
+ and you are using the same Hive Metastore, you need no further actions.
+ </p>
+
+ <ul class="ul">
+ <li class="li">
+ <strong class="ph b">HadoopTables</strong>. When the table already exists in a HadoopTable it means there is
+ a location on the file system that contains your table. Use the following command
+ to add this table to Impala's catalog:
+ <pre class="pre codeblock"><code>
+CREATE EXTERNAL TABLE ice_hadoop_tbl
+STORED AS ICEBERG
+LOCATION '/path/to/table'
+TBLPROPERTIES('iceberg.catalog'='hadoop.tables');
+ </code></pre>
+ </li>
+
+ <li class="li">
+ <strong class="ph b">HadoopCatalog</strong>. A table in HadoopCatalog means that there is a catalog location
+ in the file system under which Iceberg tables are stored. Use the following command
+ to add a table in a HadoopCatalog to Impala:
+ <pre class="pre codeblock"><code>
+CREATE EXTERNAL TABLE ice_hadoop_cat
+STORED AS ICEBERG
+TBLPROPERTIES('iceberg.catalog'='hadoop.catalog',
+ 'iceberg.catalog_location'='/path/to/catalog',
+ 'iceberg.table_identifier'='namespace.table');
+ </code></pre>
+ </li>
+
+ <li class="li">
+ Alternatively, you can also use custom catalogs to use existing tables. It means you need to define
+ your catalog in hive-site.xml.
+ The adventage of this method is that other engines are more likely to be able to interact with this table.
+ To globally register different catalogs, set the following Hadoop configurations:

+</div>
+
+ <div class="p">
+ For example, to register a HadoopCatalog called 'hadoop', set the following properties in hive-site.xml:
+ <pre class="pre codeblock"><code>
+iceberg.catalog.hadoop.type=hadoop;
+iceberg.catalog.hadoop.warehouse=hdfs://example.com:8020/warehouse;
+ </code></pre>
+ </div>
+
+ <div class="p">
+ Then in the CREATE TABLE statement you can just refer to the catalog name:
+ <pre class="pre codeblock"><code>
+CREATE EXTERNAL TABLE ice_catalogs STORED AS ICEBERG TBLPROPERTIES('iceberg.catalog'='<CATALOG-NAME>');
+ </code></pre>
+ </div>
+
+ </li>
+
+ <li class="li">
+ If the table already exists in HiveCatalog then Impala should be able to see it without any additional
+ commands.
+ </li>
+
+ </ul>
+
+
+ <div class="p">
+ You can also create new Iceberg tables with Impala. You can use the same commands as above, just
+ omit the <code class="ph codeph">EXTERNAL</code> keyword. To create an Iceberg table in HiveCatalog the following
+ CREATE TABLE statement can be used:
+ <pre class="pre codeblock"><code>
+CREATE TABLE ice_t (i INT) STORED AS ICEBERG;
+ </code></pre>
+ </div>
+
+ <p class="p">
+ By default Impala assumes that the Iceberg table uses Parquet data files. ORC is also supported,
+ but we need to tell Impala via setting the table property 'write.format.default' to 'ORC'.
+ </p>
+
+ <div class="p">
+ You can also use <code class="ph codeph">CREATE TABLE AS SELECT</code> to create new Iceberg tables, e.g.:
+ <pre class="pre codeblock"><code>
+CREATE TABLE ice_ctas STORED AS ICEBERG AS SELECT i, b FROM value_tbl;
+
+CREATE TABLE ice_ctas_part PARTITIONED BY(d) STORED AS ICEBERG AS SELECT s, ts, d FROM value_tbl;
+
+CREATE TABLE ice_ctas_part_spec PARTITIONED BY SPEC (truncate(3, s)) STORED AS ICEBERG AS SELECT cast(t as INT), s, d FROM value_tbl;

+ One can use <code class="ph codeph">DROP TABLE</code> statement to remove an Iceberg table:

+ <p class="p">
+ When <code class="ph codeph">external.table.purge</code> table property is set to true, then the

+
+ <div class="body conbody">
+ <p class="p">
+ <a class="xref" href="https://iceberg.apache.org/docs/latest/partitioning/" target="_blank">
+ The Iceberg spec </a> has information about partitioning Iceberg tables. With Iceberg,
+ we are not limited to value-based partitioning, we can also partition our tables via
+ several partition transforms.
+ </p>
+
+ <div class="p">
+ Partition transforms are IDENTITY, BUCKET, TRUNCATE, YEAR, MONTH, DAY, HOUR, and VOID.
+ Impala supports all of these transforms. To create a partitioned Iceberg table, one
+ needs to add a <code class="ph codeph">PARTITIONED BY SPEC</code> clause to the CREATE TABLE statement, e.g.:
+ <pre class="pre codeblock"><code>
+CREATE TABLE ice_p (i INT, d DATE, s STRING, t TIMESTAMP)
+PARTITIONED BY SPEC (BUCKET(5, i), MONTH(d), TRUNCATE(3, s), HOUR(t))
+STORED AS ICEBERG;
+ </code></pre>
+ </div>
+
+ <div class="p">
+ Iceberg also supports
+ <a class="xref" href="https://iceberg.apache.org/docs/latest/evolution/#partition-evolution" target="_blank">
+ partition evolution</a> which means that the partitioning of a table can be changed, even
+ without the need of rewriting existing data files. You can change an existing table's
+ partitioning via an <code class="ph codeph">ALTER TABLE SET PARTITION SPEC</code> statement, e.g.:
+ <pre class="pre codeblock"><code>
+ALTER TABLE ice_p SET PARTITION SPEC (VOID(i), VOID(d), TRUNCATE(3, s), HOUR(t), i);
+ </code></pre>
+ </div>
+
+ <div class="p">
+ Please keep in mind that for Iceberg V1 tables:
+ <ul class="ul">
+ <li class="li">Do not reorder partition fields</li>
+
+ <li class="li">Do not drop partition fields; instead replace the field’s transform with the void transform</li>
+
+ <li class="li">Only add partition fields at the end of the previous partition spec</li>
+
+ </ul>
+
+ </div>
+
+ <div class="p">
+ You can also use the legacy syntax to create identity-partitioned Iceberg tables:
+ <pre class="pre codeblock"><code>
+CREATE TABLE ice_p (i INT, b INT) PARTITIONED BY (p1 INT, p2 STRING) STORED AS ICEBERG;
+ </code></pre>
+ </div>
+
+ <p class="p">
+ One can inspect a table's partition spec by the <code class="ph codeph">SHOW PARTITIONS</code> or
+ <code class="ph codeph">SHOW CREATE TABLE</code> commands.
+ </p>
+
+ </div>
+
+ </div>
+
+
+ <div class="topic concept nested1" aria-labelledby="ariaid-title8" id="iceberg_inserts">
+ <h2 class="title topictitle2" id="ariaid-title8">Writing Iceberg tables</h2>
+
+ <div class="body conbody">
+ <p class="p">
+ Impala is also able to insert new data to Iceberg tables. Currently the <code class="ph codeph">INSERT INTO</code>
+ and <code class="ph codeph">INSERT OVERWRITE</code> DML statements are supported. One can also remove the
+ contents of an Iceberg table via the <code class="ph codeph">TRUNCATE</code> command.
+ </p>
+
+ <div class="p">
+ Since Iceberg uses hidden partitioning it means you don't need a partition clause in your INSERT
+ statements. E.g. insertion to a partitioned table looks like:
+ <pre class="pre codeblock"><code>
+CREATE TABLE ice_p (i INT, b INT) PARTITIONED BY SPEC (bucket(17, i)) STORED AS ICEBERG;
+INSERT INTO ice_p VALUES (1, 2);
+ </code></pre>
+ </div>
+
+ <p class="p">
+ <code class="ph codeph">INSERT OVERWRITE</code> statements can replace data in the table with the result of a query.
+ For partitioned tables Impala does a dynamic overwrite, which means partitions that have rows produced
+ by the SELECT query will be replaced. And partitions that have no rows produced by the SELECT query
+ remain untouched. INSERT OVERWRITE is not allowed for tables that use the BUCKET partition transform
+ because dynamic overwrite behavior would be too random in this case. If one needs to replace all
+ contents of a table, they can still use <code class="ph codeph">TRUNCATE</code> and <code class="ph codeph">INSERT INTO</code>.
+ </p>
+
+ <p class="p">
+ Impala can only write Iceberg tables with Parquet data files.

+ <h2 class="title topictitle2" id="ariaid-title9">Time travel for Iceberg tables</h2>
+
+ <div class="body conbody">
+
+ <p class="p">
+ Iceberg stores the table states in a chain of snapshots. By default, Impala uses the current
+ snapshot of the table. But for Iceberg tables, it is also possible to query an earlier state of
+ the table.
+ </p>
+
+
+ <div class="p">
+ We can use the <code class="ph codeph">FOR SYSTEM_TIME AS OF</code> and <code class="ph codeph">FOR SYSTEM_VERSION AS OF</code>
+ clauses in <code class="ph codeph">SELECT</code> queries, e.g.:
+ <pre class="pre codeblock"><code>
+SELECT * FROM ice_t FOR SYSTEM_TIME AS OF '2022-01-04 10:00:00';
+SELECT * FROM ice_t FOR SYSTEM_TIME AS OF now() - interval 5 days;
+SELECT * FROM ice_t FOR SYSTEM_VERSION AS OF 123456;
+ </code></pre>
+ </div>
+
+
+ <div class="p">
+ If one needs to check the available snapshots of a table they can use the <code class="ph codeph">DESCRIBE HISTORY</code>
+ statement with the following syntax:
+ <pre class="pre codeblock"><code>
+DESCRIBE HISTORY [<var class="keyword varname">db_name</var>.]<var class="keyword varname">table_name</var>
+ [FROM <var class="keyword varname">timestamp</var>];
+
+DESCRIBE HISTORY [<var class="keyword varname">db_name</var>.]<var class="keyword varname">table_name</var>
+ [BETWEEN <var class="keyword varname">timestamp</var> AND <var class="keyword varname">timestamp</var>]
+ </code></pre>
+ For example:
+<pre class="pre codeblock"><code>
+DESCRIBE HISTORY ice_t FROM '2022-01-04 10:00:00';
+DESCRIBE HISTORY ice_t FROM now() - interval 5 days;
+DESCRIBE HISTORY ice_t BETWEEN '2022-01-04 10:00:00' AND '2022-01-05 10:00:00';
+</code></pre>
+ </div>
+
+
+ <p class="p">

+ snapshot of the table which might have had a different schema in the past.

+ <p class="p">Impala has traditionally offered a single-byte binary character set for STRING data type and
+ the character data is encoded in ASCII character set. Prior to this release, Impala was
+ incompatible with Hive in some functions applying on non-ASCII strings. E.g. length() in Impala
+ used to return the length of bytes of the string, while length() in Hive returns the length of
+ UTF-8 characters of the string. UTF-8 characters (code points) are assembled in variant-length
+ bytes (1~4 bytes), so the results differ when there are non-ASCII characters in the string. This
+ release provides a UTF-8 aware behavior for Impala STRING type to get consistent behavior with
+ Hive on UTF-8 strings using a query option.</p>
+
