Fast key-value stores: An idea whose time has come and gone

The BeamVM languages (Erlang, Elixir) seem to have this in the form of Mnesia, and libraries that are built on top of it, such as riak-core.

Ha! I was just about to ask about that.

‘I bet Elixir already has something like this’.

Riak uses Mnesia?

Not that I know, but it uses ETS to handle state, and the global process registry to store peer information, as far as I know.

Also, be aware that OP mentioned riak-core, which is a different thing from Riak. riak-core is a library to build dynamo-style distributed applications, which gives you virtual nodes, consistent hashing and data migration as building blocks.

Riak KV uses leveldb, but as @ergl mentioned, riak-core is essentially a hash-ring and replication (aka dynamo) layer.
