> Did you find any evidence that the selectivity of predicates changes over the course of the query (or put another way that reordering them during execution would help?) I imagine that could happen, but the main point is that we start from "we know nothing" which we're treating as "nothing is selective" and then once we know a filter is selective enough we move it over to be a row filter. -- This is an automated message from the Apache Git Service.
