private void allocateValuesBuffer ( ) { int totalMiniBlockCount = ( int ) Math . ceil ( ( double ) totalValueCount / config . miniBlockSizeInValues ) ; //+ 1 because first value written to header is also stored in values buffer valuesBuffer = new long [ totalMiniBlockCount * config . miniBlockSizeInValues + 1 ] ; }
the value buffer is allocated so that the size of it is multiple of mini block because when writing data is flushed on a mini block basis
