Adding a Topic

To add a topic:

  1. Click Configuration Management >  Transformation Hub.
  2. On the Transformation Hub Configurations page, click Topics > + Add.
  3. On the Add New Topic dialog, in Topic Name, specify a name for the new topic.
  4. In Topic Type, select the type for the new topic.
Note: For Transformation Hub 3.4 and later users must select the topic type when adding the new topic. This option is disabled for Transformation Hub 3.3 or earlier.
  1. In # of Partitions, specify the number of partitions the topic will have.
  2. In Replication Factor, specify the number of copies that will be made for each partition.
  3. Click Save.
Best Practice: When creating a topic, use a value for replication factor of at least 2. In addition, the number of partitions should be equal to the number of consumers which will be subscribed to the topic (now and in future). If ArcSight Database will be a consumer, the number of partitions should be a multiple of the number of Database nodes.
