Hello Masters,
Which guarantees from CAP theorem does Couchbase satisfy.
I’d appreciate if you could shed some light regarding above guarantees and Couchbase.
Thanks in advance,

Hello,
Couchbase has been designed to be “CP”: Consistent and Partitioned.
Why not A (available)?
Simply because when a node dies, the data of these node are not available until this node is “fail over” as documented here : http://docs.couchbase.com/couchbase-manual-2.2/#couchbase-admin-tasks-failover
But keep in mind that you can use the replica read to access a replica from your application (so always available too).
I am inviting you to look a this white paper that explains the basic of Couchbase and you should be able to understand why we are Consistent and Partitioned:
Do not hesitate to ask for more informations, since this discussion could be a very long subject

Tug

Thanks a lot for fast turnaround response.
So, does Couchbase support partition tolerance, that is, network partition tolerance and recovery?
Thanks,
Erwin
