IBM StreamSets Control Hub works with Transformer to design pipelines and to execute Transformer pipelines on Apache Spark, an open-source cluster-computing framework.

You can enable a Transformer job for pipeline failover for some cluster types. Enable pipeline failover to prevent Spark applications from failing due to an unexpected Transformer shutdown.

A job tag identifies similar jobs or job templates. Use job tags to easily search and filter jobs and job templates when viewing them in the Jobs view. For example, you might want to group jobs by the origin system or by the test or production environment.

Each scheduled task has one time zone that applies to all the times configured for the task. By default, the time zone is UTC.

The Report Definitions view allows you to define a custom data delivery report that provides data processing metrics for a given job or topology. For example, you can use reports to view the number of records that were processed by a job or topology the previous day.

To generate your data delivery report, do one of the following:

To view a data delivery report, click the name of the report in the Report Definitions view. The details of the report display. Then click Show Reports.

By default, events are disabled for organizations. An organization administrator can enable events to trigger subscriptions for the organization.

A subscription is triggered by a Control Hub event. You can create a subscription for a single event type.

After an event triggers a subscription, the subscription performs an action - such as using a webhook to send an HTTP request to an external system or sending an email.

Create a subscription to listen for Control Hub events and then complete an action when those events occur.

If a subscription doesn't complete the expected action, your organization administrator can view the subscription audit entries to help troubleshoot the issue.

When you export objects that use connections or objects with dependent objects that use connections, Control Hub exports the connection metadata only. The metadata includes the connection ID, name, and type. Control Hub does not export the connection credentials or other configured values.

Control Hub authenticates and authorizes user accounts to secure the integrity of your organization and data.

Control Hub provides several types of roles that allow you to customize the tasks that users can perform.

Permissions determine the access level that users have on objects. When permission enforcement is enabled for your organization, you can share and grant permissions on objects.

Completing Control Hub tasks requires a combination of roles and permissions. The following sections list the requirements to complete common Control Hub tasks.

As a user with the Organization Administrator role, you can use the Administration view to review and manage the organization configuration, to monitor active user sessions, and to view audit entries for your organization.
