Partisan

We present the design and implementation of Partisan, an Erlang library for enabling real-world experiments of dis- tributed protocols and applications. Partisan is a \batteries- included"library facilitating internode communication in Er- lang, runtime selection of cluster topology, pluggable layers that provide additional functionality such as causal delivery and reliable message delivery, and a mechanism for perform- ing deterministic fault injection. Partisan has been used in the evaluation of one research prototype, two real-world ap- plications, and has seen industry adoption in the Erlang and Elixir communities.
