- Alpha Release. It is still missing important features, but it's usable enough for testing.
+ Alpha Release. CouchDB has not yet reached version 1.0. There will likely be data-storage
format changes and incompatible HTTP API changes between now and 1.0. However, there are projects
successful using CouchDB in a variety of contexts. See InTheWild for a partial list of projects
using CouchDB.

    * Mnesia replication is suitable for clustering, but not disconnected, distributed edits.
Most of the "cool" features of Mnesia aren't really useful for CouchDB.
    * Also Mnesia isn't really a general-purpose, large scale database. It works best as a
configuration type database, the type where the data isn't central to the function of the
application, but is necessary for the normal operation of it. Think things like network routers,
HTTP proxies and LDAP directories, things that need to be updated, configured and reconfigured
often, but that configuration data is rarely very large.

- CouchDB's data model and internal API map the REST/HTTP model so well that any other API

the HTTP API.
