I was excited to see the open sourcing of FoundationDB by Apple; it looks like it would be a great match for Elixir.
Ruby already has bindings for it – maybe someone could translate those into an Elixir adapter?
Discussion on how to go about it:
Example bindings:

What makes FoundationDB stand out?
kokolegorille
Probably the distributed nature of FoundationDB…
AstonJ
What about Mnesia
written in Erlang 
Good thread on distributed DBs here too:
darkmarmot
Mostly the distributed fault-tolerance with ACID transactions.
Many dev comments on it here:

I know we (one of my co-workers) tried a proof of concept with Mnesia and were unable to get the performance we needed on our current project – this could’ve been due to problems with our implementation or maybe it didn’t quite match our needs, I’ll have to ask to find out more.
cmkarlsson
Write performance in distributed mnesia is a bit limited and depends on the number of nodes and transaction type (async_dirty/sync_dirty/async_transaction/sync_transaction). I also remember something about a bottle-neck in file handling as there was only 1 process that wrote everything meaning you can’t split out different tables to different physical disk controllers to increase throughput (this was one thing that whatsapp patched in mnesia)
On moderate hardware we maxed out somewhere around 3000 writes/second using sync_transaction and 3 nodes. It is prone to overload and it wont stop you from doing it
. It helps if you limit concurrency to the number of schedulers.
Reads are usually faster than any other solution.

due to the way it was/is developed it’s most likely the most reliable distributed kv database out there.
cmkarlsson
That is a pretty big claim
Do you have a link to any papers/documentation where they explain what algorithms and technology they use? Their homepage was too high level and didn’t contain much information and wikipedia is light on details as well.

There is a bit more information on the forum
Technical overview of the database - Using FoundationDB - FoundationDB and in the comment section of the announcement https://news.ycombinator.com/item?id=16877395.

This video by one of the authors about how they were testing it is worth a watch https://www.youtube.com/watch?v=4fFDFbi3toc
