https://docs.ambar.cloud/ says the author's org is polling PostgreSQL (or MySQL) tables and producing records for JSON/HTTP consumers. As for me, I think a Kafka broker quorum is hard to beat for a fast and durable distributed ringbuffer.

We use Kafka under the hood. We stream instead of poll. We used to work at the Kafka team in AWS :)

Our thesis is that a big blocker is the PhD the whole team needs in Kafka. For example, if you want to set up an API similar to Ambar with tools like Kafka connect, the connectors have failure modes that will bite you once a year and bite you hard. Eg losing your changelog in MySQL, and having to start from scratch or risk losing ordering guarantees.
