…llelInputsProcessor` (pingcap#5274)" This reverts commit b62dc6a.
What problem does this PR solve?
Issue Number: close #5263 close #4856
Problem Summary:
This PR fixes two performance issues that are #5263 and #4856.
For #5263, when a query has a join then aggregation and its non-join data are enormous, this PR has a huge speedup in this scenario because multiple threads can be used to aggregate instead of a single thread in the previous implementation.
For #4856, this PR can optimize a scenario where some input streams' data are very huge and some threads may exit too early. For now, no thread can exit early. They work until all input steams are exhausted.
