Change subject: WIP [master] introduced SentryAuthzCache ...................................................................... Patch Set 5: (1 comment) http://gerrit.cloudera.org:8080/#/c/12833/5/src/kudu/master/sentry_authz_provider.cc File src/kudu/master/sentry_authz_provider.cc: http://gerrit.cloudera.org:8080/#/c/12833/5/src/kudu/master/sentry_authz_provider.cc@464 PS5, Line 464: SentryAuthzProvider::IsSameScopeHierarchyBranch I think we should try to avoid checking for each privilege in the Sentry response, and instead do a scope comparison first. Because the privileges are already filtered in Sentry side if they are on higher hierarchy scope than the requested one. For example, if the request is for 'serverS.databaseD.tableT1', then it is guaranteed to be safe to use the returned privileges to validate ''serverS.databaseD' without checking if the privilege is from the hierarchy branch. -- To view, visit http://gerrit.cloudera.org:8080/12833 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Idaefacd50736f1f152dae34e76778e17b2e84cbe Gerrit-Change-Number: 12833 Gerrit-PatchSet: 5 Gerrit-Owner: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Adar Dembo <a...@cloudera.com> Gerrit-Reviewer: Alexey Serbin <aser...@cloudera.com> Gerrit-Reviewer: Andrew Wong <aw...@cloudera.com> Gerrit-Reviewer: Hao Hao <hao....@cloudera.com> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Tidy Bot (241) Gerrit-Comment-Date: Wed, 27 Mar 2019 18:39:57 +0000 Gerrit-HasComments: Yes
