> 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).
