Matt Ingenthron in a forum thread:
There is quite a bit of work ongoing to optimize some of these paths, and there are some features coming to allow you to specify that you want to block until a change is durable at either the replication or the disk IO level. I believe use that internally to the server for prioritization as well.
Right now we write things as fast as we can and we constantly scan.
I think I’ve seen this before. And I thought Couchbase Server 2.0 will be using CouchDB durable persistence engine. Couchbase Server 2.0 is still in developer preview so there’s time for this to change. But some clarifications would be welcome.
