To implement a Go Kafka publisher and consumer group subscriber with retry control, wire the Dialer, Publisher, and Subscriber components to enforce explicit topic message usage and define handler semantics using (bool, error) returns for bounded or infinite retry rules.

Kafka consumer group handlers often fail during topic and group configuration due to misapplied retry semantics and incorrect adapter contract requirements for Dialer, Publisher, and Subscriber construction. Enforcing explicit queue message topic usage and deterministic retry rules resolves this.

The handler contract returning (bool, error) works for Kafka retries by signaling success with (false, nil) and triggering retries with (true, err). This deterministic retry control retries failed messages up to a configured MaxTryNum limit.

You do not need to configure all Kafka adapter parameters because adapter defaults exist. You only override what matters for your specific use case, such as the queue message topic, consumer group ID, prefetch, and retry or backoff settings.

The best way to avoid mixing incompatible retry and DLX mental models when integrating Kafka in Go is to use a queue Kafka adapter that enforces explicit topic-based delivery and defines strict handler semantics with bounded or infinite retry rules.

Yes, you can use this queue Kafka adapter for infinite retries within a Go service. The subscriber handler semantics allow you to define both bounded retry limits up to MaxTryNum and infinite retry rules based on the returned boolean and error values.
