stack commented on HBASE-8496:
------------------------------
I suppose bottom-line, can we not just do Cells rather than KV-with-tags? The
same problems have to be solved (basically). If Cells, you'll get your tags
carried along for you. Your CPs could then exploit them when present. The
serialization could be your proposed KV-with-tags-on-the-end but when we touch
hfile, can we pass cellblocks and read cellblocks (encoding and/or compression
could be metadata in hfile -- I suppose this means one encoding/compression per
file which is probably fine. Compressed/encoded blocks in memory would have to
be accessed w/ CellScanner... would need resettable CellScanner though I
suppose.
