Subject RE: Question: Coordinator in cassandra
Date Wed, 19 Aug 2015 04:31:13 GMT
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.

Cheers,

Subject: Question: Coordinator in cassandra

Hi all;

Please with the version cassandra 2.0.6, we have by default one coordinator per data center,
per client or per query ?

Thank you so much for help.
Kind Regards.
