Chia-Ping Tsai commented on HBASE-18770:
----------------------------------------
bq. A CP could try setting compression context, original sequence id (needed at
WAL Replay time), and replication scope can be edited as the WAL Key is
replicated to different peers. I added a warning on each CP method that WALKey
should not be modified
What we want to fix for {{WALKey}} are shown below.
# expose some methods to CP user safety
# refactor/redo
As I see it, adding an interface exposed to CP user for {{WALKey}} is a right
choice because it can bring some benefit.
# We can expose part of {{WALKey}}'s methods to CP users - a read-only
interface or an interface with some modifiable setting.
# The related CP hooks won't be deprecated
# Doing the refactor for {{WALKey}} doesn't essentially impact the CP hook
after 2.0 release. Although, it will be better to redo {{WALKey}} before 2.0
release.
In short, I think it warrants such an interface.
bq. I could file a follow-on and schedule it for beta-1.
yep, it seems a bunch of work to do. :)
