) currently pinotQuery only supports limited amount of PlanNodes this means an Exchange must be inserted in order to ensure the leaf stage can be converted into a PinotQuery. However this is a misuse of Exchange This PR plans to split the ServerRequest planning into 2 stages - first plan as much as possible into PinotQuery - for any remainder nodes that cannot be planned into PinotQuery, will be run together with the LeafStageTransferrableBlockOperator as the input locally. This PR also follows up with the refactoring from #11439. - removed server plan request context entirely and replace it with fields used by server side. - extends OpChainExecutionContext with additional info from ServerOpChainExecutionContext - break down steps from ServerPlanRequestUtils.build method into 3 parts --> - compile pinot query - convert pinot query into instance requests (based on physical segments) - construct an OpChain that sits on top Context: alternative PR to #11843 --------- Co-authored-by: Rong Rong <rongr@startree.ai>
