Hi Igor,

You can setup cluster with configuration as below.

Replication: DC1: 3 and DC2: 1.

If you are using datastax java driver, then use dcaware load balancing
policy and pass DC1, as input. As well as add DC2 node in ignore nodes, so
request never goes to that node.

Thanks,
Varun

Node containing all data of the cluster

[Igor Leão]

Hey everyone,

Imagine a have Cassandra cluster with 4 nodes.

Is it possible to have a separate node which would not receive requests but
would by in sync with the rest of the cluster? Ideally this super node
would have all data of the cluster.

I want to take a snapshot of this node from time to time in order to
reproduce scenarios that are happening in production.

Thanks in advance!
