Hi,
Since this thread already contains the system setup, I just want to ask
another question:
If you have 3 data centers (DC1,DC2 and DC3) and you have a keyspace where
the strategy options are such that each DC gets one replica. If you only
write to the nodes in one DC1 what is the path the repl
Sorry for that last message, I was confused because I thought I needed to
use the DseSimpleSnitch but of course I can use the PropertyFileSnitch and
that allows me to get the configuration with 3 data centers explained.
Cheers,
Alex

Thanks Tyler,
I see that cassandra.yaml has "endpoint_snitch:
com.datastax.bdp.snitch.DseSimpleSnitch". Will this pick up the
configuration from the cassandra-topology.properties file as does the
PropertyFileSnitch ? Or is there some other way of telling it which nodes
are in withc DC?
Cheers,

Yes, you can do this.
You will want to have three DCs: DC1 with [1, 2, 3], DC2 with [4, 5, 6],
and DC3 with [7, 8, 9]. For your normal data keyspace, the replication
strategy should be NTS, and the strategy_options should have some replicas
in each of the three DCs. For example: {DC1: 3, DC2: 3,
Hi everyone,
I want to test out the Datastax Enterprise software to have a mixed
workload setup with an analytics and a real time part.
However I am not sure how to configure it to achieve what I want: I will
have 3 real machines on one side of a gateway (1,2,3) and 6 VMs on
another(4,5,6).
