pyredlock - A Redis distributed lock implementation in Python
This python lib implements the Redis-based distributed lock manager algorithm described in this blog post.
To create a lock manager:
from pyredlock import RedisClient
from pyredlock import Redlock, Lock
...
client = RedisClient(client_conf={
"endpoint": "localhost:6379",
"password": "your_redis_password",
"db": 0,
"socket_timeout": 0.5,
"socket_connect_timeout": 0.25
})
lock_mgr = Redlock(connections=[client.get_connection()], async_mode=False)
...To acquire a lock:
...
success, my_lock = lock_mgr.lock("my_resource_name", 1000)
...To release a lock:
...
lock_mgr.unlock(my_lock)
...To extend your ownership of a lock that you already own:
...
lock_mgr.extend(my_lock, 1000)
...Disclaimer: This implementation is currently a proposal, it was not formally analyzed. Make sure to understand how it works before using it in your production environments.
