stream topic delete

Deletes the specified topic from the specified stream.

Consumers do not have to stop consuming from a topic before the topic is deleted.

The deletion of the topic and the messages is immediate. However, the command also starts a background process for the purging the topic and messages to reclaim disk space.

If the parameter -autocreate for the stream is set to true, a topic with the same name is created if a producer writes a message to a topic of the same name. For example, if you delete the topic Topic_A and then a producer writes a message to the topic Topic_A, HPE Data Fabric Streams creates a topic that is named Topic_A. Aside from the name, the new topic Topic_A shares nothing with the deleted topic Topic_A.

The mapr user is not treated as a superuser. HPE Data Fabric Streams does not allow the mapr user to run this command unless that user is given the relevant permission or permissions with access-control expressions.
