question: @ Override public DimensionColumnDataChunk [ ] readDimensionChunks ( FileHolder fileReader , int ... blockIndexes ) { DimensionColumnDataChunk [ ] dataChunks = new DimensionColumnDataChunk [ dimensionColumnChunk . size ( ) ] ; for ( int i = 0 ; i < blockIndexes . length ; i ++ ) { dataChunks [ blockIndexes [ i ] ] = readDimensionChunk ( fileReader , blockIndexes [ i ] ) ; } return dataChunks ; }
target:  Below method will be used to read the chunk based on block indexes
