Jeffrey Zhong commented on HBASE-8496:
--------------------------------------
I want to post a following user case to see if current design can accommodate
or can easily be extended to support it.
In high level, we'd like to have support of optional system tags. Basically
HBase internals can tag a KV with a value and consume these tags without using
co-processors. These tags are invisible to end users(application end users).
A possible user case(just for example as hbase-8701 may go different approach.)
is for hbase-8701 where we can tag a KV with sequence number value during log
replay and later these tags are removable by a major compaction.
Thanks.
