Concurrency

Coordinate access to shared resources across processes and machines.

• Lock — Distributed lock primitives with lease management, blocking and non-blocking acquisition, and automatic release.
• Shared Lock — Read-write distributed locks for coordinating concurrent access with shared and exclusive modes.
• Semaphore — Rate-limit concurrent access to shared resources with dynamic permit allocation.

Existing middlewares

Beyond the components themselves, every component provides middleware factories for composing component behavior around your own functions. Wrap a function with use() or method with enhance() and apply any of the following middlewares.

• withLockFactory — Wraps function calls with a distributed lock.
• withSemaphoreFactory — Wraps function calls with a distributed semaphore.
• withSharedLockFactory — Wraps function calls with a shared (reader-writer) lock.
