that PR has a very long description. At a glance it definitely seems relevant but I can't tell how long it would take to accommodate dates and I'm not sure parquet automatically maintains statistics for dates by default. Also, it doesn't seem efficient for this particular optimization because it evaluates per batch (micro-partition?) something that can be evaluated once up front. I think the only scenario it has equivalent performance is in the case of tens of batches and when the plan is not cached in any way. -- This is an automated message from the Apache Git Service.
