Allow for topic deletions with regex consumers #5230

Motivation

Currently it's not possible to delete topics when there is a regex consumer attached to them. The reason is that the regex consumer will immediately reconnect and cause the topic to be re-created.

Modifications

  • Added a flag in CommandSubscribe so that a regex consumer will never trigger the creation of a topic.
  • Subscribing to a non-existing topic, will give a specific error, that the consumer will interpret as a permanent failure and thus will stop retrying.
