Integrate Cruise Control #35

Open krallistic opened 7 years ago

krallistic commented 7 years ago

Linkedin opensourced cruise-control (https://github.com/linkedin/cruise-control) a tool to rebalance kafka-cluster. Since they have much more experience running kafka cluster, their algorithms should be used.

As a first integration, the following steps has to be done

Automatic Rebalancing of topics (if a skew occurs) is out of scope for the first integration

Right now this seems to fail with confluentinc/cp-kafka:3.3.0:

HEAD is currently pretty unstable through that refactoring. (With cruise-control unfortunately there will be custom images, based on the confluence one). A stable Version is the latest tagged version (0.2.0)
