Stream Groups

Use stream groups to run, or schedule, two or more streams in sequence.Â
Streams may be grouped if there are dependencies between the streams. A typical example is when one of the streams in a given group must run successfully before subsequent streams can be executed. The stream group feature handles such situations by stopping the run if any stream fails.
Note!
It is recommended to use Notification groups to receive information about failing streams in groups.
Streams must be created, and belong to the same solution before they can be grouped. For information on how to create streams, see Streams. At the end of this documentation, you find screenshot-based examples of stream group actions.Â
Create a stream group
Once you have created a solution with the streams needed, you can group the streams in that solution. To create a stream group, select the streams you want to group and click Create group 
Enter a name for the group in the Stream group name. Drag the stream in the execution order you want it to run.
You can add additional streams into the stream group, by clicking Add streams and selecting the other streams in the solution.
Click Create. A stream group is now created and ready for any of the stream group actions.
Note!
Streams within a stream group cannot be deleted, scheduled or run independently.Â
Stream Group Actions
Once a stream group is created, the following actions can be taken:
Action | Description |
|---|---|
Start | Select start to run the stream group immediately. |
Stop | Select stop to immediately halt a running stream group. If the stream group is scheduled, it will run at the next specified interval. To permanently stop a scheduled stream, the schedule must be canceled. This action is only visible when a stream group is running. |
Schedule | Select the schedule to specify the interval for when you want the stream group to run. The intervals are selectable on the following basis: Minute, Hour, Day, Week, and Month. |
Cancel schedule | Select Cancel schedule to delete the schedule for the stream group. When you confirm to cancel the schedule, the schedule is deleted. This action cannot be undone. If the schedule has started, all streams run before the schedule is canceled. This action is only visible when the stream group is scheduled. |
Edit | Select edit to make changes to a stream group. You can change the name of the group and re-order the streams. Note! If a stream group is scheduled, the streams can not be re-ordered. Cancel the schedule to re-order the streams. |
Ungroup | Select ungroup to move all streams from the stream group, return the individual stream to the Streams View, and delete the stream group. This action cannot be undone. |
Stream Actions
When a stream is a part of a group, the following actions can be taken:
Action | Description |
|---|---|
View stream | View the stream in the stream editor. See Stream Editor for more information. |
Edit | Select edit to make changes to a stream. You can change the name and logic, that is the desired result, of the stream. You can edit a stream in a group at any time, even when the stream group has a scheduled run. See Stream Editor for more information on stream editing. |
Log | Select view log to get details of the events generated for every run of the stream. See Logs for more information about view logs. |
Audit | Select to view the audit data. See Audit Log for more information. |
Set notifications | Select set notifications to inform a pre-defined mailing group about stream events or issues that interrupt the stream group run. For more information about notifications, see Notification groups. |
Rename | Rename the stream. |
Export | This will open up the Export Stream modal used to copy down the content of the given stream. You can either copy the contents using the Copy to Clipboard button or download the stream content in a JSON file format. |
Examples
When a stream group is created, the initial actions are the following: Start, Schedule, Edit, and Ungroup. Once a group is scheduled and started, three more actions are available: Stop, View schedule, and Cancel schedule.
When the Schedule option is selected, you can choose the interval between runs.
Once the interval is chosen, click Save settings to save the settings.
Click Publish in the confirmation dialog to activate the schedule.
If you want to cancel the schedule, click Cancel schedule, and confirm by clicking Ok in the confirmation dialog.Â
You can stop the stream group run by selecting Stop.
