Open Source is not dead: On the recent demise of RethinkDB
We discussed this recently at Couchbase, where I work. Couchbase is mostly open source. You can build most components of the database system, but the installer and some of the more enterprisy bits of the codebase are closed-source. You could, say, build the complete query engine and drop the very latest code into an existing installation.<p>We don&#x27;t have any users who contribute to the codebase. But there are a few elite users out there who build their own components for debugging purposes. This lets them send us very precise bug reports that get acted on quickly.<p>So, all in all, we get a little bit of benefit from being mostly open source.
