James Taylor commented on PHOENIX-1812:
---------------------------------------

I think it's best if you return a PTableRef from PMetaData.getTable() instead 
of a PTable and add a getResolvedTime() method. Adding it to PTable wouldn't 
work well, because we cache the PTable on the server and we wouldn't want to 
create a new PTable each time it's resolved to update it.

> 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.
