Publishing options

After adding your Kafka topic and creating an option, you can publish your option to a set of gateway groups which will make it available in the catalog.

All the published options are displayed in the Event Endpoint Management catalog as event endpoints, along with event source name, tags, and status information. The event source owner can edit or delete their options after publishing them, as described in managing options.

Application developers can then discover available event endpoints and subscribe to them directly or request access if approval is required.

Before you begin

A gateway is required to publish an option. Ensure that you have at least one gateway group associated with your Event Manager instance. For more information, see managing gateways.

Publishing options

To publish an option to the catalog, complete the following steps:

Note: The controls within an option cannot be edited or deleted after the option is published.

  1. Log in to the Event Endpoint Management UI by using your login credentials.
  2. In the navigation pane, click Manage topics. A list of event sources is displayed.
  3. Select the event source that you want to publish an option from.
  4. Click the Options tab.
  5. For the option that you want to publish, click Publish.

  6. In the Publish option dialog, select a gateway group from the available options.

    Note:

    • When only one gateway is available, it is selected by default. If you have multiple gateways, you can choose a gateway group from the available options.
    • Some controls require a supported gateway. For example, you can only add the quota enforcement control to gateways that are version 11.3.0 and later. If you attempt to publish an option to a gateway that does not support specific controls, a notification is displayed to inform you that this action is not possible.
  7. Click Publish.
  8. To cancel changes, click Cancel.

Viewing published options

After the option is published, application developers can discover and learn more about the corresponding event endpoint in the Event Endpoint Management catalog.

To view the option within the Event Endpoint Management catalog, complete the following steps:

  1. Log in to the Event Endpoint Management UI by using your login credentials.
  2. In the navigation pane, click Catalog.
  3. Select the event source that the option belongs to from the list.
  4. Select the event endpoint card that with the published option name at the top.

After you select an event endpoint, you can view the description and event information. Based on this information, you can subscribe to the event endpoint to get access, or request access if an approval control is enabled on this event endpoint. You can also export an event endpoint as an AsyncAPI document.
