Hi Honza,

seconds and our tests are significantly slowed down.
I think the reason why it retried for 30-40 seconds is that you tried to
create topics via adminClient (new KafkaAdmin.NewTopics) as described in
the Spring-Kafka KafkaAdmin javadoc here
<https://github.com/spring-projects/spring-kafka/blob/main/spring-kafka/src/main/java/org/springframework/kafka/core/KafkaAdmin.java#L52-L53>.
*/*** An admin that delegates to an {@link AdminClient} to create topics
defined* in the application context....*/public class KafkaAdmin extends
KafkaResourceFactory ...*
And because the error `DisconnectException` is a retriable exception, Kafka
will keep retrying until `timeout`.

completely forbids the connection attempts, or at least forces the client
to try it only once?
I think it doesn't make sense when you want to use Kafka and create topics,
you forbid the connection attempts to brokers. But I think you can try to
reduce the retry/timeout value in adminClient. The config `retries` in
admin client config here
<https://kafka.apache.org/documentation/#adminclientconfigs_retries> might
be the one you're looking for. To set it to `0`, will not retry if
retriable error happened, or try to config the `request.timeout.ms` or `
default.api.timeout.ms` for timeout setting.
Hope that helps.
Thank you.
