concurrency-patterns

Prevent race conditions and deadlocks by selecting an appropriate concurrency pattern such as single-writer actors or lock-free techniques, and specifying strict invariants and liveness constraints to preserve correctness under load.

Choosing a concurrency pattern for asynchronous coordination involves comparing single-writer actors, lock-based, lock-free, and immutable snapshot strategies to identify which approach best mitigates contention while maintaining performance for your shared mutable state.

Document a concurrency strategy by explicitly specifying invariants, liveness constraints, and monitoring signals, alongside a verification plan including stress and race tests to validate the chosen pattern under load.

You need lock-free techniques when optimizing for high contention and low latency, whereas immutable snapshot strategies are preferred when safely sharing read-heavy state across parallel execution tasks without complex synchronization locks.

Verify your concurrency pattern handles parallel execution loads by executing a structured verification plan that applies stress tests and race tests to validate invariants and liveness constraints under simulated high-load conditions.
