> If all the tables of the cluster have been migrated to the new index coprocs
> (GlobalIndexChecker, IndexRegionObserver), for every mutation, we should
> avoid making additional rpc call to master to retrieve TableDescriptor to
> determine if the table descriptor has GlobalIndexChecker coproc enabled:
> {code:java}
> at
> org.apache.phoenix.query.ConnectionQueryServicesImpl.getTableDescriptor(ConnectionQueryServicesImpl.java:605)

> We already use config "phoenix.index.region.observer.enabled" to
> disable/enable new index coproc during upgrade. The primary purpose of this
> config is to add/remove new or old index coprocs during upgrade process.
> We can introduce new config "phoenix.index.region.observer.enabled.alltables"
> with default value true. Unless the config is disabled, we should avoid call
> to "IndexUtil#isGlobalIndexCheckerEnabled" withinÂ
> filterIndexCheckerMutations().
