Venu Yanamandra updated HIVE-21178: ----------------------------------- Description: Based on the sql scripts present for derby db, the size of COLUMNS_V2[COMMENT] is 4000. [https://github.com/apache/hive/tree/master/metastore/scripts/upgrade/derby] However, if we see those present in say - mysql, we see them limited at 256. [https://github.com/apache/hive/tree/master/metastore/scripts/upgrade/mysql] For a requirement to store larger amount of comments, non-derby dbs limit the maximum size of the column comments. Kindly review the discrepancy. was: Based on the sql scripts present for derby db, the size of COLUMNS_V2[COMMENT] is 4000.
