Subject [jira] [Commented] (HBASE-18127) Enable state to be passed between the region observer coprocessor hook calls

Anoop Sam John commented on HBASE-18127:
----------------------------------------

May be there are no such cases now? But it is possible to come. Ya what I was interested in
is a general solution. We have this ThreadLocal issue some other places also. That part of
code executed by a thread a pool. We need a generic solution. If u can try out some thing
general which we can use throughout, that would be awesome. Good one Abhishek

> Allow regionobserver to optionally skip postPut/postDelete when postBatchMutate was called.
> Right now a RegionObserver can only statically implement one or the other. In scenarios
where we need to work sometimes on the single postPut and postDelete hooks and sometimes on
the batchMutate hooks, there is currently no place to convey this information to the single
hooks. I.e. the work has been done in the batch, skip the single hooks.
> There are various solutions:
> 1. Allow some state to be passed _per operation_.
> 2. Remove the single hooks and always only call batch hooks (with a default wrapper for
the single hooks).
> 3. more?
> [~apurtell], what we had discussed a few days back.
