Brook: Distributed Event-based Orchestration in Elixir
summary
Brook is an event-stream library that wires microservices with an event bus (Kafka by default, Redis for dev), serializes events to JSON with __brook_struct so structs survive language boundaries, and stores per-component view state that is cached in memory (inets) and persisted for replay and crash recovery. Handlers implement a single callback with multiple pattern-match heads, adapters let you swap Kafka/Redis/Postgres later, and dynamic supervisors rehydrate jobs from view state; it is running in production data pipelines.
