Handling Redis failure
I have the following architecture:
Timeline data for users are added to the cache when they are posted.
If older data are requested but they can't be found in the cache, I go to the database.
This is all ok.
But I wonder how the problem should be fixed if Redis fails; in that case the strategy fails. New posts don't get written to the cache, so they cannot be retrieved when Redis gets up again either.
What is the usual way to handle this problem?

To mitigate component failures, you can deploy Redis in a highly-available fashion.
