Subject [jira] [Created] (KAFKA-10418) Unclear deprecation of altering topic configs via kafka-topics with --bootstrap-server
Date Tue, 18 Aug 2020 20:15:00 GMT
Ron Dagostino created KAFKA-10418:

             Summary: Unclear deprecation of altering topic configs via kafka-topics with
                 Key: KAFKA-10418
                 URL: https://issues.apache.org/jira/browse/KAFKA-10418
             Project: Kafka
          Issue Type: Improvement
            Reporter: Ron Dagostino
            Assignee: Ron Dagostino
             Fix For: 2.7.0

Changing a topic config with the kafka-topics command while connecting to Kafka via --bootstrap-server
(rather than connecting to ZooKeeper via --zookeeper) has been deprecated.  The desired functionality
is available elsewhere: it is possible to change a topic config while connecting to Kafka
rather than ZooKeeper via the kafka-configs command instead.  However, neither the kafka-topics
error message received nor the kafka-topics help information itself indicates this other possibility.
 For example:

{{$ kafka-topics.sh --bootstrap-server localhost:9092 --alter --topic test --config flush.messages=12345
Option combination "[bootstrap-server],[config]" can't be used with option "[alter]"

{{$ kafka-topics.sh
--config <String: name=value>            A topic configuration override for the topic
being created or altered...It is supported only in combination with -- create if --bootstrap-server
option is used.

Rather than simply saying that what you want to do isn't available, it would be better to
say also that you can do it with the kafka-configs command.
