When we were considering how to push 700k events per minute from Kafka into our data warehouse, Vertica, we learned these lessons about how to choose the best framework for high throughput.

It helps us easily scale our service, and gives us some resilience when problems inevitably happen in production. In this post, I’ll cover two problems - auto down and quarantine - and share our lessons learned.
