stack commented on HBASE-7897:
------------------------------
Ok. Tags are opaque byte arrays at this level. Whether there is one tag or
100 in the array of bytes and how to parse the bytes is for figuring elsewhere.
Below the Cell level, the tag representation can be compressed or encoded but
by inspection of the raw bytes themselves, not by exploiting some Tag aspect.
Sounds like the additional methods would be the below only?
+ /**
+ * @return the tag byte array
+ */
+ byte[] getTagArray();
+
+ /**
+ * @return the first offset where the tags start in the Cell
+ */
+ int getTagsOffset();
+
+ /**
+ * @return the total length of the tags in the Cell.
+ */
+ int getTagsLength();

> Cell Interface has suppport for mvcc. The only thing we'd add to Cell in
> the near future is support for tags it would seem. Should be easy to add.
> Should add it now. See backing discussion here:
