Partisan is a flexible, TCP-based membership system for Erlang/Elixir.

Partisan features:

• Single node testing, facilitated by a disterl control channel for figuring out which ports the peer service is operating at.
• Messages are sent via TCP connections that are maintained to all cluster members.
• Failure detection is performed TCP.
• Connections are verified at each gossip round.
• Configurable fanout.
• On join, gossip is performed immediately, instead of having to wait for the next gossip round.
• HyParView implementation.

Partisan has many available peer service managers:

• Full membership with TCP-based failure detection: partisan_pluggable_peer_service_manager.
• Client/server topology: partisan_client_server_peer_service_manager.
• HyParView, hybrid partial view membership protocol, with TCP-based failure detection: partisan_hyparview_peer_service_manager.
• Static topology: partisan_static_peer_service_manager.
