Description

problem: Data mismatch after compaction with measure sort columns

root cause : In compaction flow (DictionaryBasedResultCollector), in ColumnPageWrapper inverted index mapping is not handled. Because of this, row of no dictionary dimension columns gets data form other rows.

Hence the data mismatch

 

solution: Handle inverted index mapping for  DictionaryBasedResultCollector flow in ColumnPageWrapper
