             Summary: [Hive] Advance write ID for remaining DDLs
                 Key: HIVE-25372
                 URL: https://issues.apache.org/jira/browse/HIVE-25372
             Project: Hive
          Issue Type: Sub-task
          Components: HiveServer2
            Reporter: Kishen Das
            Assignee: Kishen Das


We guarantee data consistency for table metadata, when serving data from the HMS cache. HMS cache relies on Valid Write IDs to decide whether to serve from cache or refresh from the backing DB and serve, so we have to ensure we advance write IDs during all alter table flows. We have to ensure we advance the write ID for below DDLs.
