What kind of delivery guarantees does this offer? And does it provide data replay?

Currently evaluating https://sequinstream.com/ which claims sub-200ms latency, but has a lot of extras that I don’t need and a lighter weight alternative would be nice.

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 :) )

You can get single digit latency with almost anything for CDC to queue if you properly colocate your services & your CDC ingestion is keeping up with postgres slot

Should have specified; this is for tracking bursts of up to 1.5k tps not in the same AZ or even VPC.

No guarantees on latency as this depends on the hardware.
