stack commented on HBASE-16134:
-------------------------------
When do we ever want to emit tags? When debugging?
WAL write time is 'write time' so when Cell comes in the front door, we use a
write-time Cell that will include tags when we call write. Otherwise, when we
pull from hfile, we use a Cell type that does not include tags? If debug, pass
a flag and then use a different Cell type, one that will do debug things
including emitting Tags?
> Introduce Cell extension for server side.
