The main application scenarios are: one-time scheduled tasks with changing requirements.
Execute corresponding commands by monitoring redis expiration events. (Note: Because monitoring can only get the key, you need to store the specific execution content separately)
Also remember to modify the redis configuration: notify-keyspace-events Ex
import redis
rdc = redis.StrictRedis()
pubsub = rdc.pubsub()
pubsub.psubscribe("__keyevent@0__:expired")
while pubsub.subscribed:
msg = pubsub.get_message()
if msg:
print msg
