Vaxine, the Rich-CRDT Database for Elixir/Phoenix Applications

CRDTs are key ingredient for low latency, collaborative applications. However, typical backend applications require more from their database than just commutativity. Vaxine is a new database system developed in Erlang and Elixir, based on AntidoteDB, that extends CRDTs with invariant safety and makes a CRDT database easy to use from Elixir and Phoenix applications. This talk explains the rationale for a rich-CRDT database and introduces the open-source Vaxine system.


Introduce the Vaxine system and help the audience understand when and how they might use it.
