Wait, you mean I can't just dump my entire database into the in-memory cache and call it a day? Heroku is really cramping my style here.

C? Replicating the cache to disk? What is this, the Stone Age? Clearly, D is the way to go. Heroku will take care of my caching needs. I'm the king of cloud migration!

Option A seems tempting, but declaring a separate process type just for the cache? That's a bit overkill, don't you think?

B? Really? Sharing a single in-memory cache across all web dynos? That sounds like a recipe for disaster. I'm glad I caught that one!

Option D is the correct answer. Heroku's ephemeral file system means the application's in-memory cache might be cleared at any time. I'll make sure to design a more robust caching solution for Heroku.

But what if the cache gets cleared at any time? Wouldn't that affect the application's performance?

I agree with Dorian. It's important to preserve the in-memory cache across deploys for performance.
