Kafka's scalability

[Péter Sinóros-Szabó <pe...@wise.com.INVALID>]

Hi,

We have a Kafka cluster that's growing a lot year to year and I was
wondering how much it can handle without custom changes.

If you're running a large Kafka cluster or if you're aware of one, please
share some data around it:
- how many brokers is in the cluster and CPUs / RAM used
- how many topics / partitions it has
- number of messages incoming
- number of consumers / producers it supports

This could help us to see how large we can grow our clusters.

Thanks,
Peter
