> In the issue #12561, all fields (include pk and not null fields) are nullable when parquet file was clustered by spark row writer. If we just focus on nullability of pk field, I am worried that flink will still not be able to perform clustering on those files that have been clustered by spark row writer in the presence of NOT NULL constraints. Checked the #12561 again, the scenario you mentioned is a problem. As we have already checked nullable schema can be used to read non-nullable schema data file, I'm ok to force all non-null fields being nullable for cluster reading. cc @danny0405 WDYT -- This is an automated message from the Apache Git Service.
