Partisan is a scalable, TCP-based membership system and distribution layer for the BEAM that replaces Distributed Erlang with pluggable overlay network backends. It enables high-performance distributed actor applications with configurable topologies, named channels, and message delivery guarantees.

Use cases

• scale an Erlang cluster beyond Distributed Erlang's node limits
• build a peer-to-peer gossip-based membership protocol on the BEAM
• run geo-distributed actor applications with lower latency
• separate control-plane and user messages across parallel TCP channels
• implement a custom overlay network with minimal code
• broadcast messages reliably across a large Erlang/Elixir cluster

When to choose

• you need clusters larger than Distributed Erlang comfortably supports (hundreds to thousands of nodes)
• you want pluggable overlay topologies like full-mesh, client-server, or HyParView
• you need channel affinity, parallel connections, or custom failure detection
• you're building distributed actor systems in Erlang or Elixir

When to avoid

• you have a small cluster where standard Distributed Erlang works fine
• you need a battle-tested, mainstream clustering solution with a large community
• your project doesn't run on the BEAM (Erlang/Elixir/OTP)
• you need causal delivery guarantees in production (still experimental)
