-----------------------------------------------
[~jeffreyz]
bq.Basically HBase internals can tag a KV with a value and consume these tags
without using co-processors.
The HBase internals will know about the tags and the read and write path would
know how to deal with them. But they will just read the tag part of the KV
from the bytebuffer and return back as KVs with or without tags as per that
individual KV.
If we need to take specific action for the system tags on the read path, then
we need to add the behaviour inside the HBase read path. Currently this would
be handled by CPs based on the type of the tags.
So may be once i attach a first cut version of the patch you would be able to
understand better.
