I think the main reason such a property would be interesting for dask's use case is to get the number of row groups in a case all statistics are not available / not yet parsed. So the way that this PR returns `None` in that case is not super useful, I think. I think ideally if the number of row groups is not know (the row_groups are not set), it would retrieve this information from the FileMetaData. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
