James Taylor commented on PHOENIX-4616:
---------------------------------------
Instead of this:
{code}
+ if (dataPlan instanceof BaseQueryPlan) {
+ return getApplicablePlans((BaseQueryPlan) dataPlan, statement,
targetColumns, parallelIteratorFactory, stopAtBestPlan);
+ }
{code}
can you do this?
{code}
if (dataPlan.getSourceRefs().size() == 1) {
return getApplicablePlans(dataPlan, statement, targetColumns,
parallelIteratorFactory, stopAtBestPlan);
}
{code}

> Currently we do optimization for join queries inside QueryCompiler, which
> makes the APIs and code logic confusing, so we need to move join optimization
> logic into QueryOptimizer.
> Similarly, but probably with a different approach, we need to optimize UNION
> ALL queries and derived table sub-queries in QueryOptimizer.optimize().
