callback when key expires in Redis

[prk2331]

Team,
Could you please explain to me how we can get a callback when the key expires in Redis? After that, I'd like to run my Revenue Calculation logic. 

Im using django redis cache in django http sessions
I have an API to calculate the revenue logic, which runs on logout, and I want to automate this as well if the redis key expires.

Thanks

hello @prk2331,

same issue was opened a long time ago and it is #363.

We're not interested in developing such a thing, you should use celery with a delayed task, it is the easier way.

If you really want to shoot yourself in the foot you could try using pubsub and keyspace notifications
