    Description

      public Cell getFirstKeyCellInBlock(ByteBuff block) {
    block.mark();
    block.position(Bytes.SIZEOF_INT);
    int keyLength = ByteBuff.readCompressedInt(block);
    // TODO : See if we can avoid these reads as the read values are not getting used
    ByteBuff.readCompressedInt(block);

      In DBEs many a places we read the integers just to skip them. This JIRA is to see if we can avoid this and rather go position based, as per a review comment in HBASE-12213.
