MongoDB in "subscribe" on Redis

Is it possible to configure an architecture with Redis in "master" and MongoDB in "slave" in order to automatically persist in MongoDB some volatile information in Redis?

Example: persist in MongoDB a list of notifications for a user created in Redis.

Not directly.

However, you could imagine to maintain a synchronization list in Redis to queue all the changes that have to be sent to MongoDB. Then, you can add a daemon listening to the Redis synchronization list, and applying the changes to MongoDB.

The implementation of a true guaranteed delivery mechanism (i.e. once and only once semantic) is difficult though.
