> I was afraid that writers might populate the statistics with a default value (e.g. `0`) if all of the rows are null instead of `null`. And that some other pass might then remove the information on row count / null counts resulting in: > > row_count null_count min max > null null 0 0 if all values are null, then all non-null values are in [0, 0] range, so min=0 and max=0 would be valid. -- This is an automated message from the Apache Git Service.
