I received a phone call from couchbase company in April of this year. They asked me which language I use for programming.
I think this is due to how couchbase make money. From the information on the website, they provide project team members for a team of project teams for a fee, depending on the days or hours.
These members ( couchbase employee) should use the same language as their clients, most clients use C #, java, python. Therefore, they simply provide these languages, not erlang.
For an average period (1 or 2 years), I think it is not possible to provide erlang sdk from couchbase.
