Removing topics

Removing topics is as easy as adding them. Typically, applications will want to remove topics that represent a transient stream of data, such as an active user's location, where the latest value is no longer needed.

When a topic is removed, all subscribers will receive a notification that the topic has been removed, but they will remain subscribed - meaning that if the topic is created again, they will continue to receive updates without having to re-subscribe.

Removing individual topics

Removing with selectors

You can also remove topics with topic selectors. This allows you to easily remove large parts of the topic space with a single request.
