Hi Michael, Ben and Johs, Thanks for your responses. I've found for my (admittedly small) projects Couch works pretty well on the Pi (version 2). It's a great solution to the problem of where to store metadata, and how to query it easily. The only performance problem I saw was when reducing and grouping queries, e.g. here I used a memo to cache results: https://github.com/ericclack/clojure-photo-bank/blob/master/src/clj/clojure_photo_bank/models/db.clj#L45 ...running the query took about 5 seconds for around 4000 records. That's not great, but for everything else Couch was easily fast enough.
I'm going to explore Erlang packages for Raspbian and then look at compiling a few different versions of CouchDB to see if I can at least get some good bug reports to the right team. Many thanks, -Eric.
