Browse Event Streams and Visualize their Relationships

This tutorial will teach you how to search and filter events, schemas, and applications in Catalog. The following topics are covered in this tutorial:

  1. Browse Published Objects in Catalog
  2. Visualize Object Relationships

Before you Begin

  • To complete these tutorials, you must have a PubSub+ Cloud account. If you haven't already, complete the Accessing PubSub+ Cloud tutorial.
  • Ensure that you have the correct user role and permission in Event Portal. At minimum, you will need the Event Portal Manager permission. For more information, refer to Managing Users, Roles, and Permissions. Note that the Administrator, Event Portal Manager, and Event Portal Viewer user roles will all count towards the Event Portal's maximum user limit.

Browse Published Objects in Catalog

To browse for an event, application or schema in Catalog, do the following:

  1. Log in to your PubSub+ Cloud account.
  2. Click the Catalog card or select Catalog on the left navigation bar.
  3. Select Schemas, Events or Applications tab.
  4. Click on the search field and enter your search term. The system looks for content in all objects of that type (within the metadata or schema, if searching schemas). You can also use the filters to browse for objects based on whether the object type is shared, within a specific application domain, or owned by a particular user. Furthermore, you can filter events based on a Topic Scheme or search for applications based on an Application Class.

Once you've found an application, event, or a schema of interest, you can perform additional tasks such as Visualize Object Relationships.

Visualize Object Relationships

The ability to view relationships is an important feature. For example, a data scientist may know the name of a JSON Schema attribute and could search schemas for that keyword. From there, he can locate the schema of interest and view the events which reference that schema. Furthermore, the user can now decide to consume one of these events, depending on the business context of the event and the problem they are trying to solve.

To visualize object relationships in Catalog, perform the following tasks:

  1. Log in to your PubSub+ Cloud account.
  2. Select the Catalog card or click Catalog on the left navigation bar.
  3. On the top menu, select Schemas, Events or Applications tab.
  4. Click an object of your choice to view its corresponding relationships.
