lasp-lang/partisan

Partisan is a distributed overlay network library for Erlang/OTP that enables reliable, high-performance communication between nodes in a cluster. It provides a pluggable architecture for broadcast substrates and remote procedure calls, supporting multiple membership and consensus protocols. The system includes comprehensive tooling for static analysis, automated testing, and performance benchmarking to ensure correctness and measure throughput.

This period focused on the Partisan v6.0.0 release, which introduced a complete architectural rewrite for OTP compatibility, including a new TCP-based peer service and compile-time AST transformation. The work also involved adding comprehensive test suites and header files to support the new configuration and utility structures.

This period focused on expanding the system's capabilities by adding new distributed consensus and replication protocols, alongside their corresponding static causality and message flow analyses. The team also established a comprehensive automated testing and analysis infrastructure, including scripts for model checking, fault injection, and performance benchmarking across various implementations.

5 changes

This period focused on establishing performance measurement capabilities through a new benchmarking framework and documenting the architectural shifts in the broadcast substrate and RPC system. The team also expanded test coverage by adding helper modules for TS installation and implementing a Fly.io-based test runner for heavy suites.
