question: @ Override public int fillChunkData ( byte [ ] data , int offset , int index , KeyStructureInfo keyStructureInfo ) { if ( chunkAttributes . getInvertedIndexes ( ) != null ) { index = chunkAttributes . getInvertedIndexesReverse ( ) [ index ] ; } System . arraycopy ( dataChunk , index * chunkAttributes . getColumnValueSize ( ) , data , offset , chunkAttributes . getColumnValueSize ( ) ) ; return chunkAttributes . getColumnValueSize ( ) ; }
target:  Below method will be used to fill the data based on offset and row id
