> Another theory I want to test out is that it could be related to more IOs with filter pushdown -- I have an idea of how to test that theory, but I probably won't have time to test it for another few days Doesn't this PR at least establish that that is maybe not the biggest contributor, to tpch at least? I.e. I think this PR is showing that just moving where the (non pushdown, so same I/O pattern) filtering happens causes a performance degradation (unless I'm doing something wrong with the filtering itself) -- This is an automated message from the Apache Git Service.
