@nsivabalan In the RFC， key format is [ColumnId] [PartitionId] [FileId]/ [ColumnId] "agg" [PartitionId]，it will using hash32/hash128 to generate unique IDS，would like to know how to guarantee the uniqueness between two different columnNames/PartitionValues/FileNames after hash32/hash128? Cause once two different ColumnNames have the same ID after hash32, it may lead a wrong pruning results. -- This is an automated message from the Apache Git Service.
