[jira] [Created] (SENTRY-157) Support filter pushdown in DB Store
client to reduce data transfer from DB Store service
Prasad Mujumdar created SENTRY-157:
--------------------------------------
Summary: Support filter pushdown in DB Store client to reduce data transfer from DB Store service
Key: SENTRY-157
URL: https://issues.apache.org/jira/browse/SENTRY-157
Project: Sentry
Issue Type: Bug
Affects Versions: 1.4.0
Reporter: Prasad Mujumdar
The authorization provider retrieves all the privileges for the given set of groups. This could be a huge data set if there are a large number of privileges in the system. A downstream consumer like HiveServer2 will be reading this for each query. This could impact the DB store performance if there are multiple active queries and numerous privilege rules.
We could consider pushing the filters like DB object name to the policy provider to prune the privilege result set at the source.
