[jira] [Created] (SENTRY-2210) AUTHZ_PATH should have index on the foreign key AUTHZ_OBJ_ID

Na Li created SENTRY-2210:
-----------------------------

             Summary: AUTHZ_PATH should have index on the foreign key AUTHZ_OBJ_ID
                 Key: SENTRY-2210
                 URL: https://issues.apache.org/jira/browse/SENTRY-2210
             Project: Sentry
          Issue Type: Improvement
          Components: Sentry
    Affects Versions: 2.1.0
            Reporter: Na Li
            Assignee: Na Li


AUTHZ_PATH does not have index on the foreign key AUTHZ_OBJ_ID. When the number of entries become really large, a command like "select * from AUTHZ_PATH where AUTHZ_OBJ_ID = 8311512" becomes very slow because it results in table scan.

To improve performance, we should add index for its foreign key in table AUTHZ_PATH.

The sql script to do this in Oracle is "CREATE INDEX AUTHZ_PATH_FK_IDX on AUTHZ_PATH(AUTHZ_OBJ_ID);"
