[jira] [Created] (HIVE-25543) Add Read-Only Capability to ObjectStore

David Mollitor created HIVE-25543:
-------------------------------------

             Summary: Add Read-Only Capability to ObjectStore
                 Key: HIVE-25543
                 URL: https://issues.apache.org/jira/browse/HIVE-25543
             Project: Hive
          Issue Type: Improvement
            Reporter: David Mollitor
            Assignee: David Mollitor


Recently saw some stack-traces that shows that calling "commit" triggers quite a bit of work within DataNucleus, as I understand it, to look for changes in the transaction and to commit those changes.

Given that many of the RPCs within the Metastore are look-ups, Hive can avoid all these needless work by making transaction read-only (rollbackOnly).
