----------------------------------
Summary: Topic existence checks in topic commands (create, alter,
delete)
Key: KAFKA-3084
URL: https://issues.apache.org/jira/browse/KAFKA-3084
Project: Kafka
Issue Type: Improvement
Reporter: Grant Henke
Assignee: Grant Henke
In Kafka 0.9.0 error codes were added to the topic commands. However, often
users only want to perform an action based on the existence of a topic. And
they don't want to error if the topic does or does not exist.
Adding if-exists option for the topic delete and alter commands and
if-not-exists for the create command allows users to build scripts that can
handle this expected state without error codes.
