- In a DMS you can have each DMA with its corresponding local Cassandra node running on the same server.
- On the other hand you also have the option to have a centralized Cassandra cluster running on separate servers.
Is it supported to have both of the above architectures in the same DMS? I.e. some agents in the cluster have their own cassandra DB and some are contacting the Cassandra cluster?
Going one step further, can you have multiple Cassandra clusters in a DMS?
Reason of this question is because in my scenario, the DMAs are physically distributed across the entire world. I'd like to know if we can have a Cassandra clusters in each region perhaps.
Hi Jochen,
At the moment Cassandra Cluster is not yet released.
However it is not the plan to support a mixed configuration with the initial release.
The goal is to have one Cassandra Cluster for your DMS. The main reason why we will not support mixed configuration is to avoid complex scenario's for other features that are on the roadmap (e.g. Swarming).
In Cassandra there are a lot of possibilities in configuration related to DC and so on. For example the following blog could help you a lot: https://www.datastax.com/blog/2011/03/deploying-cassandra-across-multiple-data-centers
