Overview -------- For critical pieces of code that cannot overlap with one another, it is often necessary to acquire a mutex lock of some sort. Many solutions use a memcache lock strategy, however, this strategy can be brittle in the case of memcache going down or when an unconsistent hashing function is used in a distributed memcache setup. If your application does not need a high performance mutex lock, Django DB Mutex does the trick. The common use case for Django DB Mutex is to provide the abilty to lock long-running periodic tasks that should not overlap with one another. Celery is the common backend for Django when scheduling periodic tasks.
