Description

What would you like to be improved?

In catalogs/catalog-jdbc-doris/src/main/java/org/apache/gravitino/catalog/doris/utils/DorisUtils.java, checks for a missing bucket group, preventing errors when the BUCKETS clause is absent and defaulting to 1 or AUTO as appropriate.

Here's a test to help:

  @Test
  public void testDistributionWithoutBucketClauseDefaultsToOne() {
    String createTableSql =
        "CREATE TABLE `testTable` (\n" +
        "`col1` date NOT NULL\n) ENGINE=OLAP\n PARTITION BY RANGE(`col1`)\n()\n DISTRIBUTED BY HASH(`col1` )";
    Distribution distribution = DorisUtils.extractDistributionInfoFromSql(createTableSql);
    assertEquals(distribution.number(), 1);
  }

How should we improve?

Contributor guide

Research direction
Inspect the failing test and trace the handler path in DorisUtils.java to understand how the bucket clause is parsed and where the AUTO handling logic should be added.
