Replication - In Memory or on disk? And can persistence be disabled?
I am looking at using Couchbase to implement my cache. I was attracted by its replication/persistence, as I need these for handling session data.
However, I was wondering if buckets are replicated onto other nodes in memory or onto disk? I would presume they are replicated onto disk to ensure maximum RAM availability? I cannot find clarification on this. I definitely don't want my cache capability halfed by a 2GB cache taking up 4GB of RAM!
Also, can persistence be disabled? Potentially looking at porting another project to couchbase, but I would want persistence disabled, but replication enabled.
