How to enable a Cassandra node to participate in multiple cluster

[Salih Kardan <ka...@gmail.com>]

Hello everyone,

I want to use Cassandra cluster for some specific purpose across data
centers. What I want to figure out is how can I enable a single Cassandra
node to participate in multiple clusters at the same time? I googled it,
however I could not find any use case of Cassandra as I mentioned above. Is
this possible with the current architecture of Cassandra?

As far as I know nodes are identified by ip address and ports defined in
yaml. If you carefully prepare configuraton you should be able to run
multiple Cassandra processes on single box participating in different
clusters. If you decide to use separate ip address and default ports it
should be quite easy. Nowadays when docker is in place you could put
cassandra in container or use any kind of vms.

Hello Salih,

As far as I'm aware a node can't be in two clusters. In the casdandra.yaml
file you can only specify one cluster. The storage system and all the
protocols would have to be modified so information about multiple clusters
is passed around. I'm sure somebody else could give you more and accurate
detail.

If your saving on hardware then you could think about using docker or
virtualisation , but you'll have problems with performance. A bit like the
problems you get when you have small instances at Amazon.

Thanks
