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);"
