A topic is an entity that represents a data domain that is published and consumed in
Cloud Integration Hub
. A topic defines the data structure and additional data definitions, such as the data retention period. Multiple applications can publish to the same topic. An application can subscribe to multiple topics.
For example: Create an Accounts topic into which two CRM applications, a current application and a legacy application, publish accounts data. The marketing application and the data warehouse subscribe to the data in the Accounts topic.
