> Filter execution is also a bit different. Would it be a reasonable experiment to take FilterExec and make it evaluate each predicate independently to see if we can reproduce the slowdown? I feel the intuition is that if there are some very selective predicates evaluating those first, slicing and then evaluating the rest is beneficial because you immediately discard work. But maybe the overhead of slicing the data is high enough that this is not worth it unless the filter is very selective (and with contiguous ranges) *and* the other filters are very expensive? -- This is an automated message from the Apache Git Service.
