Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).
Motivation
In kafka-topic.sh, we expect to use --if-exists to ensure that the topic to create or change exists. Similarly, we expect to use --if-not-exists to ensure that the topic to create or change does not exist. Currently, only ZookeeperTopicService supports these two options and we want to introduce them to AdminClientTopicService.
Public Interfaces
kafka-topic.sh:
The topic command will accept either --if-exist or --if-not-exist option together with --bootstrap-server option.
Proposed Changes
Implement the logic in AdminClientTopicService like what ZookeeperTopicService has.
Add support to ensure the topic exists in:
- alterTopic()
- describeTopic()
- deleteTopic()
Add support to ensure the topic does not exist in:
- createTopic()
