Why does redis clean up when a snapshot occurs?

Question

Django

jung project. connected django-redis-cache
There is a container and three services: nginx, project, redis.
the project connects to redis and everything works fine until redis does the persistence. After saving, the data is cleared and again everything works as expected, but without the previous data. I did volume on the .rdb file, to no avail.
Is there a vm over commit memory warning in the logs, maybe because of it?

Answer 1

Maybe Django puts TTL on the keys and they are automatically deleted?
I recommend making redis-cli monitor . See what's running between Django and radish
