> As part of PHOENIX-1734 we need to write the index updates to same region from coprocessors but writing from batchMutate API is not allowed because of mvcc.
> Raised PHOENIX-2742 to discuss any alternative way to write to the same region directly or not but not having any proper solution there.
> Currently we have provision to write wal edits from coprocessors. We can set wal edits in MiniBatchOperationInProgress.
> {noformat}
> /**
> * Sets the walEdit for the operation(Mutation) at the specified position.
> * @param index
> * @param walEdit
> */
> public void setWalEdit(int index, WALEdit walEdit) {
> this.walEditsFromCoprocessors[getAbsoluteIndex(index)] = walEdit;
> }
> {noformat}
> Similarly we can allow to write mutations from coprocessors to memstore as well. Or else we should provide the batch mutation API allow write in batch mutate coprocessors.
