CockroachDB as Distributed Queue

Has anybody used CockroachDB as distributed queue or topic ? How was the experience?
I am looking at 8K Messages per second on average
I dont want to invest in other solutions to keep tech stack simple.

For what it’s worth, we (Cockroach Labs) have a simple queue workload that we use to test things. Maybe you can customize and use it yourself.
The source is in here.
I believe you run it with something like

make bin/workload
./workload run queue --concurrency=<x>
