Remember: This implementation is not suitable for synchronization of distributed processes.

Configuration parameters

  • options:
    • retry_timeout: timeout in milliseconds to retry lock acquisition. (Default: 100)

Example

var lock = MemoryLock();
        try {
        lock.acquire("123", "key1")
            // Processing...
        } finally {
            lock.releaseLock("123", "key1",
                // Continue...

        }
