Dear All,

I am looking around for possible alternative storage engines for a large cdo/emf model collection.

I spotted a bunch of commits wrt couchbase which was an engine I was considering e.g.:

/couchbase/plugins/org.eclipse.emf.cdo.tests.couchbase/src/org/eclipse/emf/cdo/tests/couchbase/AllTestsCouchbase.java

& was wondering if it ever got to a useable stage? Whether couchbase was a good platform for cdo/emf etc?

i.e. was there a reason apart from lack of time that it was never finished to the degree of making it onto the list of cdo istores?

If not then any ideas wrt how much time it would require & if so.....if it would be worth it? (i.e. if there is not some fundamental problem with it as a solution).

TIA

Adam

I vaguely remember that a "formerly active" CDO committer brought this topic up but I thought that never resulted in
working code and commits. Maybe Vik remembers...

I doubt it. Not in CDO. Maybe somewhere else?

I don't know enough about Couchbase to answer this question ;-(

As I don't know much about Couchbase I would roughly estimate something between two and six weeks. But only if it
(unlike for example MongoDB) supports proper transactions with ACID properties.
