      Description

      This include fixes with

      • Replace KeyValue#heapSize() with CellUtil#estimatedHeapSizeOf(Cell)
      • Printing the key portion of a cell (rk+cf+q+ts+type). These are in Exception messages
      • HFilePrettyPrinter - Avoiding ensureKeyValue() calls and calls to cell#getxxx() which involves bytes copying. This is not a hot area still we can avoid as much usage of deprecated methods as possible in core code. I believe these bytes copying methods are used in many other parts and later we can try fixing those as per area importance
      • Creating CellUtil#createKeyOnlyCell and using that in KeyOnlyFilter
