Use stream groups to run, or schedule, two or more streams in sequence. 

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. 

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 Create group.png .
