Lars Hofhansl commented on HBASE-4210:
--------------------------------------
+1 on patch (both 0.94 and 0.96).
MiniBatchOperationInProgress is still a bit questionable (slightly overkill.
IMHO, just to hide the array offset). Also this won't allow the RegionObserver
to interfere with the batch of operations (for example removing one), but I
guess that would be tricky anyway.
> Allow coprocessor to interact with batches per region sent from a client(?)

> Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly
> one row|cell operations.
> It might be a good idea to allow a coprocessor to deal with batches of puts
> and deletes as they arrive from the client.
