Changing Replication details after keyspace is created

[rickalm]

Has any thought been given to evaluating the replication defined in the yaml file vs the actual keyspace deployed in cassandra. We discovered its not possible to alter the replication in the yaml file and have it take effect, it only happens if creating the keyspace.

I've used a migration to do it when I required, which has the advantage of ensuring the change is documented. Any particular reason for wanting it to be automatic? Em Ter, 14 de nov de 2017 22:15, Rick Alm <[email protected]> escreveu:

In our case the datacenter names are different for each profile, a single migration is problematic.
I know I could "overload" the replication, but between our three "profiles" we share a datacenter and I dont want to start naming DC's env-geo

I see what you mean. I won't have time to think about this too much for the next week or so, but you consideration is valid and I'll try to address the need in the future. Em Ter, 14 de nov de 2017 22:55, Rick Alm <[email protected]> escreveu:
