Question

I am pretty sure it does, but I wanted to double check, since I don’t know exactly how Passenger restarts a rails app. So if I have something like:

Rails.cache.fetch(:my_obj) { MyObj.first }

will all the cache be cleared upon restart (which is my hope)?

Answer 1

If you are using MemoryStore then yes, this cache will disappear when Passenger restarts.

Also, a quote from the API:

If you’re running multiple Ruby on
Rails server processes (which is the
case if you’re using mongrel_cluster
or Phusion Passenger), then this means
that your Rails server process
instances won’t be able to share cache
data with each other.
