[jira] [Created] (PHOENIX-1812) Prevent attempt to sync table metadata unless necessary

James Taylor created PHOENIX-1812:
-------------------------------------

             Summary: Prevent attempt to sync table metadata unless necessary
                 Key: PHOENIX-1812
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1812
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor
            Assignee: Thomas D'Silva


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.
