(Updated Jan. 4, 2018, 12:26 a.m.) Review request for sentry, Alexander Kolbasov, Brian Towles, kalyan kumar kalvagadda, Na Li, Sergio Pena, and Vadim Spector. Repository: sentry Description (updated) ------- When Solr is using Sentry server for authorization, it issues a lot of calls to getGroupsByRoles() function in DelegateSentryStore. This function isn't very efficient - it walks over each role in the set, obtains role by name, get groups for each role, and collects all group names into a set. It may be possible to optimize it. Also, in SentryGenericPolicyProcessor class method list_sentry_roles_by_group() would make N transactions to build the roles to set of groups map. Instead, make it to a single transaction. This will significantly speed up operation Attach one or more files to this issue Diffs ----- sentry-provider/sentry-provider-db/src/main/java/org/apache/sentry/provider/db/generic/service/persistent/DelegateSentryStore.java 4cb46abc5 sentry-provider/sentry-provider-db/src/test/java/org/apache/sentry/provider/db/generic/service/persistent/TestDelegateSentryStore.java 69d16238f Diff: https://reviews.apache.org/r/64661/diff/4/ Testing ------- mvn -f sentry-provider/sentry-provider-db/pom.xml test Thanks, Arjun Mishra
