Fun anecdote; a couple years ago I started writing a Kafka alternative in C++ with a friend. I got pretty far, but abandoned the project.
We called it `tuberculosis`, or `tube` for short; of course, that is what killed Kafka.
Imagine talking to your clients about tech stacks and "we're running tuberculosis" comes up... while people are dying from it.
"Consumption" works too :)
Assuming topics are consumed in your version, a la Kafka.
