------------------------------------------------
Nice suggestion. Yes observerContext to make it generic can be passed from the
RPccallContext that is availble per RPC call.
Is it also avialable for RegionServer related RPC calls that are like admin
calls? I hope yes.
> 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.
