yeah, I agree if your requirements is data consistency then not Elasticsearch, however I think from the Jepsen tests I don't think there has been any NoSQL db that performs really good on that? ( I seem to remember there was one that did bad on the first test but improved a lot with the second - SOLR, CouchDB?)

you're thinking of RethinkDB https://aphyr.com/posts/329-jepsen-rethinkdb-2-1-5

Thanks! I knew someone would have either a better memory than me or the willingness to actually go to http://jepsen.io/analyses.html and figure out which one it was! And now that I went I see both the ones I thought it might be haven't even ever been done!
I need to run a Jepsen test on my brain.
But for reading it's fine. So by all means, you can populate from a main data store that you never otherwise touch.
Then again, if you're running just a single instance on really small data... What could go wrong?
Edit: Again, small stuff, locally, it's probably fine. But ElasticSearch wasn't really built to be a primary data store.
