Andrew Purtell commented on HBASE-4210:
---------------------------------------
bq. The main concern is how we can pass the mutations which are handled in a
current Mini batch.
Yes, I propose you don't do that, and instead inform the CP when a batch is
starting, when the batch has completed, and by inclusion of an RPC id in hook
upcalls for the individual ops in the batch, what ops below to what batch RPC
(by ID).
This way there is no expensive construction of a large data structure.
> Allow coprocessor to interact with batches per region sent from a client(?)

> Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly

> It might be a good idea to allow a coprocessor to deal with batches of puts
> and deletes as they arrive from the client.
