Anyone have experience / opinions on Kafka? We currently don't have a messaging system like this, and I'm thinking it would be the best choice for things like providing webhooks because its persistent nature, instead of having a "synchronous" message queue that I push into and hope it gets handled. Might also want to store attempted webhook calls in a db but I don't know if that's overkill and could be done with just transforming messages (if they fail) and trying to handle them again.
