> CSV/JSON reader path: short inputs cost 1-2 ns more per value, while long Decimal256 inputs are ~35% faster. End-to-end, CSV reads of decimal columns are ~8% slower. I suspect there is room for further optimization here (which will now benefit both code paths!) to reach or exceed the previous performance, but I'd like to land the unified parser first before we tackle further optimizations. were these based on new benchmarks? i cant seem to spot any decimal read paths in our existing csv/json benchmarks -- This is an automated message from the Apache Git Service.
