> I was mentioning this PR to @crepererum and he also noted there is another interesting potential optimization when we know the predicate is true for the entire row group: we can skip evaluating the predicate for the row group entirely (as the filter can often be quite expensive itself) > > @xudong963 is this something else you are contemplating? This PR likely lays the foundation for such an optimization. If you think it is worthwhile I'll file a ticket This is a very nice optimization that we’ve put into our data aware cache layer. It makes a lot of sense because it’s a no-trade off optimization, if it can be applied it’s always a win. -- This is an automated message from the Apache Git Service.
