Andrew Purtell commented on HBASE-9816:
---------------------------------------
For HBase internals, 256 type codes is overkill but it's hard to know how many
user types will be wanted.
As for the size short, is a tag with a size that uses all those bits too big?
Maybe.
But let's say we use two bytes overall. 4 for type is only 16 tag types. That
leaves 12 bits left for length. That's 4k max tag length. Too small for some
uses by far.
There is a whole file optimization similar to what's done with memstoreTS.
Could also consider a block header but we have not done this as of yet because
encoders will handle tags in their own way.
