Hi, maybe you can check this ticket https://issues.apache.org/jira/browse/HIVE-26227
Thanks, Butao Zhang ---- Replied Message ---- | From | Flavio Junqueira<f...@apache.org> | | Date | 11/15/2023 17:26 | | To | <user@hive.apache.org> | | Subject | Question on Hive Metastore catalog support | Hello there, I'm interested in understanding the Hive Metastore catalog support. I see references in the metastore code to catalogs, for example: https://github.com/apache/hive/blob/17525f169b9a08cd715bfb42899e45b7c689c77a/standalone-metastore/metastore-common/src/main/protobuf/org/apache/hadoop/hive/metastore/hive_metastore.proto#L45 But I don't see create/drop catalog statements in the HiveQL DDL, neither in the documentation nor in the code: https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL https://github.com/apache/hive/tree/17525f169b9a08cd715bfb42899e45b7c689c77a/ql/src/java/org/apache/hadoop/hive/ql/ddl Could anyone clarify the state of support for catalogs in the metastore? Are there known applications leveraging this catalog support? Thanks, -Flavio
