This is great stuff!<p>I was wondering though, looking at the stack, if some parts couldn&#x27;t be substituted with &quot;lighter&quot; alternatives? I&#x27;m assuming couchbase is being used for the changes feed and since you can&#x27;t do adhoc querying you need &quot;elastic search&quot; for that, however wouldn&#x27;t it be possible to replace both with just rehinkdb? Anyway I&#x27;m just speculating here, I should probably dig into the code.<p>Thanks for sharing this and keep up the good work!<p>Update: seems you&#x27;ll still need elastic search for rethinkdb full text search [0]<p>[0] <a href="http:&#x2F;&#x2F;www.rethinkdb.com&#x2F;docs&#x2F;elasticsearch&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.rethinkdb.com&#x2F;docs&#x2F;elasticsearch&#x2F;</a>
