Docker Compose aside ...
Maybe Knative will beat us to the Kafka sidecar pattern :) but development today with countless restarts of a service that needed to warm up a kafka connection only for simple table-topic lookups got me thinking about the advantages with a kafka-cache sidecar.
Also integration testing required kafka while all I'd actually want was to pre-load some key-value pairs. Maybe something like https://www.npmjs.com/package/jsondown could provide that. The sidecar pattern would make kafka-cache and a stub interchangeable at runtime.
While I was in this mood I also had crazy ideas about using annotations to declare what topics and/or types to produce and/or consume, as solution to Yolean/kubernetes-kafka#101. Maybe CloudEvents will beat us to that :)
