Subject RE: Question: Coordinator in cassandra

Hi Thouraya,

In all versions of Cassandra, each query will have one coordinator. Any node in the cluster
can be the coordinator and this is choice is made by the client/driver. The coordinator may
or may not have a replica of the data being requested.

Thank you so much for help.
