A row mutation is a request to store columns in one or more CF's using one row
key. It is treated as indivisible by the c
When the coordinator node receives a batch_mutate for __one__ row key
associated with different mutations for different CF :

communications/requests to replicas (even if in that case, the replicas are the

When the coordinator node receives a batch_mutate with different N row keys
(for different CF) :
a) does it treat them as N independent requests to replicas, or
b) does the coordinator node split the the initial batch_mutate into M
batch_mutate (M <= N) according to rowkeys ?
Thanks,
