Yeah, they finally released the 2.0.0 BETA...
What does this mean? As far as I know / have tested the CPU utilization issues seem to be solved (http://www.couchbase.com/issues/browse/MB-6413). You know, when running the Couchbase Server with more than five buckets, the old 2.0 builds were consuming all CPU ressources with NO traffic. Just running the server was a big mess. But they fixed this.
Also (prior the last build before beta) there were no working backup and or restore tools. Now they work like a charm... if you know about the possible drawbacks.
So I wrote this little shiny piece (ironic) of documentation for Crowdpark: https://github.com/Crowdpark/crwd-tools/wiki/Couchbase-Management
Of course this is nothing which explains a lot... but it helps... at least I hope so.
