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 replicas.

 

Does anyone know enough of the inner working of Cassandra to tell me how much work is needed to patch Cassandra to enable such communication vectorization/batch ?

 

Thanks.

 

Regards,

Dominique
