I've just implemented an Erlang binding for Vedis which is called Evedis. It uses Erlang Native Implemented Functions (NIF) for wrapping Vedis library to be used inside Erlang application.
Also I have plan to create fragmented database using key hashing in Erlang side for having the power of Erlang concurrency for data read and write.
Evedis repository URL is: https://github.com/hamidreza-s/evedis
So happy to have your feedbacks.
