Andrew Purtell commented on HBASE-18127:
----------------------------------------
Also may need this cross hooks outside of RPC, so perhaps attached to the
environment not the RPC call context.
> Enable state to be passed between the region observer coprocessor hook calls

> 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.
