Assuming you mean "have the coordinator send multiple row read/write requests
in a single message to replicas"
Pretty sure
Hi,
We are created a new partitioner that groups some rows with **different** row
keys on the same replicas.
But neither the batch_mutate, or the multiget_slice are able to take
opportunity of this partitioner-defined placement to vectorize/batch
communications between the coordinator and the
