What problem does this PR solve?
This pull request updates the logic for determining required data distributions in the aggregation and join pipeline operators. The main focus is on improving the handling of exchange types, especially for passthrough and broadcast scenarios.
Key changes include:
Data distribution logic updates:
DistinctStreamingAggOperatorX, the method now always returnsExchangeType::PASSTHROUGHinstead of delegating to the base class, simplifying the distribution requirement when colocation is not needed.HashJoinProbeOperatorX, the logic for broadcast joins is refined: if the child is a serial operator, it returnsExchangeType::PASSTHROUGH; otherwise, it returnsExchangeType::NOOP. The handling of bucket shuffle and colocate join distributions is also clarified.Check List (For Author)
