Debezium published this doc on Exactly-once delivery with their most recent 3.3.0 version. They dont support it natively, but say it can be achieved via Kafka Connect
You could probably achieve something similar with the NATS Jetstream sink as well, which has similar capabilities - though I think it doesnt have quite the same guarantees.
I switched to using Debezium a few months ago, after a Golang alternative to Debezium + Kafka Connect - ConduitIO - went defunct. I should have been using Debezium all along, as it is clearly the most mature, most stable option in the space, with the best prospects for long-term survival. Highly recommended, even if it is JVM (though they're currently doing some interesting stuff with Quarkus and GraalVM that might lead to a jvm-free binary at some point)
