bitnami-docker-kafka VS examples

Regarding Kafka, try the Bitnami image, and see their GitHub page which has most of what you need to spin up a simple node: https://github.com/bitnami/bitnami-docker-kafka

I am using Bitnami's Docker Image for Kafka. It is well documented and frequently updated. We will be doing a straight forward setup and add a firewall allowing only the private/public ips that belongs to our application servers.

Relevant: - Suggested Enhancements to Python Producer Example

If you'd like to get a better idea of how it works when implemented in code, there are some sample repositories here https://github.com/confluentinc/examples/

Spend some time on https://developer.confluent.io , especially https://developer.confluent.io/get-started/java/ and look at https://github.com/confluentinc/examples . Those will give really practical examples for how to set up your configs and start consuming

The examples git repo has a great working producer and consumer. https://github.com/confluentinc/examples

Digging into this a bit, I guess the fastest way would be to use librdkafka via Dart FFI. It's what Confluent uses in their Node.js example. That way you only have to worry about the FFI parts.
