Hi,
the default definition of the keyspace system_distributed is:
CREATE KEYSPACE system_distributed WITH replication = {'class':
'SimpleStrategy', 'replication_factor': '3'} AND durable_writes = true;
If I understand correctly, every repair information will be replicated on three
servers in the cluster. I have changed the RF to '1'. Once i stop the entire
cluster, the replication factor changes again to 3. It seems Cassandra wants it
to be 3.
Doesn`t that reduce performance on repair operation?
Why is the RF changed again after restart the cluster?
Are there reasons why you shouldn`t change the replication factor to 1?
Thanks,
Marcel
