First time I've heard of KIP-932 and it looks very good. The two biggest issues IMO are finding a good Kafka client in the language you need (even for ruby this is a challenge) and easy at-least-once workers.

You can over partition and make at-least-once workers happen (if you have a good Kafka client), or you use an http gateway and give up safe at-least-once. Hopefully this will make it easier to build an at-least-once style gateway that's easier to work with across a variety of languages. I know many have tried in the past but not dropping messages is hard to do right.

Couldn’t agree more - the most exciting thing about KIP-932 is how much easier it’ll become to build a good HTTP push gateway.

Uber wrote a Kafka push gateway years ago, when it was considerably harder to do well: https://www.uber.com/blog/kafka-async-queuing-with-consumer-...

Do you mind explaining what you mean by not being able to find a "good Kafka client" for Ruby? There are pretty good bindings to librdkafka and frameworks like Karafka (https://github.com/karafka/karafka/) that provide many functionalities, including a Web UI.

Late reply... I don't have my notes anymore on kafka client evals in ruby. When evaluating it was for a former employer. Karafka is very impressive though. Well done on the library.
