James Taylor commented on PHOENIX-1812:
---------------------------------------
What do you think, [~maryannxue]? Did you try this, [~tdsilva]? Seems a bit odd
to check the select statement for equality.
{code}
- context.setResolver(FromCompiler.getResolverForQuery(select,
this.statement.getConnection()));
+ // if select statement is the same just use the original
resolver
+ if (innerPlan == null &&
tableRef.equals(resolver.getTables().get(0))) {
+ context.setResolver(this.resolver);
+ }
+ else {
+
context.setResolver(FromCompiler.getResolverForQuery(select,
this.statement.getConnection()));
+ }
{code}
> 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.
