Distributed readers-writer lock in python

QUESTION

Distributed readers-writer lock in python

Asked 2020-Apr-05 at 16:31

I am looking for a readers-writer lock that can be used in python in a distributed system.

So far I've found:

redlock, which is based on redis. Does not provide a readers-writer lock.
The distributed package of dask offers a lock, but again, no readers-writer lock.
kazoo, which works with Zookeeper, offers a readers-writer lock. However Zookeeper is an extremely heavy dependency, as it written in Java and therefore requires the JDK.

Is there a more lightweight alternative to kazoo / Zookeeper? Ideally a pure python solution that is nevertheless battle tested?

Redis is single-threaded and read/write operations are atomic; which means multiple simultaneous read/write operations will not succeed and readers and writer(s) will be obtaining access to the resource sequentially in atomic fashion. I believe this would solve your problem if the resource is kept in as one of the redis data structures. You do not need a separate reader-writer lock mechanism when using redis and python as combination where the resource is kept within redis.

Hope it helps
