[jira] [Created] (HIVE-23361) Optimising privilege synchroniser

Simhadri G created HIVE-23361:
---------------------------------

             Summary: Optimising privilege synchroniser
                 Key: HIVE-23361
                 URL: https://issues.apache.org/jira/browse/HIVE-23361
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Simhadri G


Privilege synchronizer pulls the list of databases, tables and columns from the Hive Metastore. For each of these objects it fetches the privilege information and invokes HMS API to refresh the privilege information in HMS. This patch store the privilege information as bit string. This is done to reduce the size of the tbl_col_privs tables in metastore.
