> block.position(Bytes.SIZEOF_INT);
> int keyLength = ByteBuff.readCompressedInt(block);

> ByteBuff.readCompressedInt(block);
> {code}
> 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.
