From the Ubuntu mailing list:
From the first days of Ubuntu One, before we were even in Ubuntu, we’ve
had a structured data storage sync service based around CouchDB.
For the last three years we have worked with the company behind CouchDB
to make it scale in the particular ways we need it to scale in our
server environment. Our situation is rather unique, and we were unable
to resolve some of the issues we came across. We were thus unable to
make CouchDB scale up to the millions of users and databases we have in
our datacentres, and furthermore we were unable to make it scale down to
be a reasonable load on small client machines.
Because of this, we are turning off most of our CouchDB-related
For these same three years we have created and maintained desktopcouch,
which is a desktop service (and related library) to access CouchDB more
conveniently. Because we are no longer going to pursue CouchDB, we will
no longer be developing desktopcouch;
CouchDB Twitter account’s only comment:
Reports of my death are greatly exaggerated.
I’m filing this under what happened to CouchDB popularity.
