Maryann Xue commented on PHOENIX-1812:
--------------------------------------
Thanks, [~tdsilva], for the improved change! [~jamestaylor] Comparing the
SelectStatement may solve the non-join query cases' problem, but optimally we
would want to cover all cases, including join queries I think.
> Only sync table metadata when necessary

> With transactions, we hold the timestamp at the point when the transaction
> was opened. We can prevent the MetaDataEndpoint getTable RPC in
> MetaDataClient.updateCache() to check that the client has the latest table if
> we've already checked at the current transaction ID timestamp. We can keep
> track of which tables we've already updated in PhoenixConnection.
