It’s not quite ready, but at the request of an interested party, I made the github repository public. One more (successful) rebuild-from-scratch and I’m calling it good.
In addition to getting Pulsar Manager running, finally, I wrote (trivial) tests for both Pulsar and Cassandra. They work!
BLEK is still missing. Jaeger is a possibility. But, I want to start using the thing, so once it rebuilds as-is, I’m declaring victory and moving on.
