Publish/subscribe topics hierarchy deployment

If you are using publish/subscribe, deploy the topics hierarchy in these situations:
There are two ways of deploying a publish/subscribe topics hierarchy:

Complete topics deployment

A complete topics deployment sends the publish/subscribe topics hierarchy to all the brokers in a domain.

When to use it
  • If you have made changes to the topics hierarchy and one of the brokers has an inconsistent view of the expected topics hierarchy.
  • If you have added a new broker to the domain that uses the topics hierarchy.
When not to use it
  • If you have changed the topics hierarchy. In this case, a delta topics deployment is usually sufficient.

Delta topics deployment

A delta topics deployment sends the publish/subscribe topics hierarchy to all the brokers in a domain.

When to use it
  • If you have made changes to the topics hierarchy.
When not to use it
  • If the topics hierarchy has not changed.
