Hi, The main (current) difficulties in running CouchDB on embedded devices is running erlang there coupled with our clustering stack. To scale everything down to fit within the typical constraints of an embedded device requires effort, I don’t think couch “just works” there.
The future release that replaces the clustering technology with FoundationDB is what I refer to by “getting harder in the future”. While fdb does scale down well, it might still need porting to platforms it’s not currently supported on. As for suitability for IoT, couch is certainly used in that field, but care must be taken, especially around the core notion that couch retains information about a deleted document forever. This small amount of data can build up, and you need to plan for it.
