> I personally think it would be more useful to make scanners that are more robust against large row groups (e.g. pyarrow's could be improved) by supporting reading at the page level instead of the row group level (still not 100% convinced this is possible). So at the moment I'm still leaning towards 1Mi but I could be convinced otherwise. I agree with this assessment. For highly selective / single row reads, we should be optimizing the PageIndex and Page pruning paths. That work seems to be in progress: * Read: https://github.com/apache/arrow/issues/33596 * Write: https://github.com/apache/arrow/issues/34053 -- This is an automated message from the Apache Git Service.
