…fferManager listeners Pass an OutputBufferManager-backed listener factory into PrestoIterativePartitioningSerializer so the optimized path uses the same listener source as normal PartitionedOutput. Create per-partition listeners during flush, set the checksum bit only when a listener is present, and compute the page checksum only for PrestoOutputStreamListener instances. Also add tests that verify checksum headers are written and that the serialized pages round-trip through the standard deserializer.
…rting - add explicit simple-schema benchmark cases by type and column count - register normal and optimized runs as separate named benchmark cases - make `dictPct` apply per generated vector and recurse into nested types - generate benchmark input vectors directly with optional nulls - replace ad hoc flat input generation with explicit input specs - return `ExchangeRunStats` from benchmark runs and centralize query config - group printed results by dataset with normal vs. optimized stats
