             Summary: Improve Sentry memory usage by interning object names
                 Key: SENTRY-1758
                 URL: https://issues.apache.org/jira/browse/SENTRY-1758
             Project: Sentry
          Issue Type: Sub-task
          Components: Sentry
    Affects Versions: sentry-ha-redesign
            Reporter: Alexander Kolbasov
            Assignee: Alexander Kolbasov
             Fix For: sentry-ha-redesign


During testing we discovered that a lot of memory is used by full snapshots and 
there are a lot of duplicate strings which should be the case for things like 
role names, group names and object names (dbs, tables, etc). 

We should be able to save a bunch of memory there by interning these.
