> @kumarUjjawal any status update on this? Based on the reported benchmark number: - TPC-H is approximately 10.7% slower. - TPC-DS is approximately 4–5% slower, although it uses less memory. - ClickBench is approximately 3.75–3.83× slower overall. Q33 and Q34 are approximately 9× slower, and both process memory and MemoryPool reservations increase. - wide_schema failed while running the disabled baseline, so it does not provide a comparison. These results reproduce the earlier performance direction. I think the implementation needs to avoid automatically promoting high-cardinality or dictionary-fallback columns. -- This is an automated message from the Apache Git Service.
