Hi, I'd like to restore a configuration for a topic which was previously overriden with the AdminClient provided in the kafka-client library.
For example if I create a topic "test-topic" with the configuration " delete.retention.ms=86400001", I'd like to be able to reset this configuration to default afterwards, without even knowing the default. I thougth this would be possible by passing null as value to the configuration property I would like to reset, but that gives me a NullPointerException on the Broker. With the kafka-config I can easily achieve this by executing: ./kafka-configs.sh --entity-type topics --entity-name test-topic --zookeeper localhost:2181 --delete-config delete.retention.ms --alter Is this even possible with AdminClient? Best regards Malte
