It's all just kafka and mongo. The event can be stored in any simple k/v storage. There's no magic.
Edit: not sure why I'm being downvoted. I work at stripe and this is literally how it works.

Years ago there wasn't even a Kafka portion, that's newer.
One thing I really admire is how Stripe makes it transparent which events were fired both in general through the Developer area, and on specific objects like customers, subscriptions, etc..
