I looked at sequin just now and wish they published their benchmark code. I’m curious how they configure Debezium. At 500 change/s, I get ~90ms average latency with my Debezium cluster after fiddling with Debezium options a bunch.

I don’t love Debezium but I also don’t love Erlang, plenty of us have scars from RabbitMQ’s weird sharp edges…

Sequin engineer here. We'll publish our benchmark repo soon! Indeed, we're still doing a lot of fiddling with Debezium ourselves to make sure we cover different configurations, deployments, etc.

The main thing we want to communicate is that we're able to keep up with workloads Debezium can handle.

(And, re: RabbitMQ, I wouldn't write off a platform based on a single application built on that platform :) )
