Can Couchbase Server work with RAM memory only?

Question

We want to take advantage of the No-Sql Databases in our applications, and we found out about Couchbase.

I've read about it on another stack question, where somebody says that you can configure Couchbase to work with Memcached only (so it saves data only on memory, not on disks also).

However, i haven't found anything about this in the documentation.

Is it possible to setup Couchbase server to work with RAM memory?

Or, you specify on the client side where the data should be saved? (disk or memory)

Answer 1

Yes, Just use memcached buckets. That's all

Answer 2

Check out: http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-introduction-basics.html

Couchbase 2.0 documentation explicitly states that it's an in-memory database. From my experience the buckets all exist in RAM. You can set the size of every bucket to partition your RAM appropriately.
