-------------------------------------
Summary: Optimize rpc call to master if all indexes are migrated
to new coprocs
Key: PHOENIX-7230
URL: https://issues.apache.org/jira/browse/PHOENIX-7230
Project: Phoenix
Issue Type: Improvement
Affects Versions: 5.1.3
Reporter: Viraj Jasani
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}
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" within filterIndexCheckerMutations().
