Lock¶

Tooz provides distributed locks. A lock is identified by a name, and a lock can only be acquired by one coordinator at a time.

from tooz import coordination

coordinator = coordination.get_coordinator('zake://', b'host-1')
coordinator.start()

# Create a lock
lock = coordinator.get_lock("foobar")
with lock:
    print("Do something that is distributed")

coordinator.stop()

The method tooz.coordination.CoordinationDriver.get_lock() allows to create a lock identified by a name. Once you retrieve this lock, you can use it as a context manager or use the tooz.locking.Lock.acquire() and tooz.locking.Lock.release() methods to acquire and release the lock.
