Stream Hosts are grouped into different Collections, which are created and maintained in Data Stream Designer. A Collection can be defined as a category that contains a set of Stream Hosts that run the same Data Streams. Collections are used to prevent you from having to redeploy a Data Stream to multiple Stream Hosts, devices, and assets. When a Data Stream is published for a Collection, the devices themselves can just subscribe to that Collection.
It is recommended that you read the article listed below to improve your understanding of Collections.
Collections are an important concept in the Data Stream Designer. You might have to create a Collection soon after starting to use the Application as they are crucial to the workings of use cases and Streams. A Collection also has to be created before installing a Stream Host as the Stream host is dependent on the information contained in a Collection. To create a Collection, follow the steps below:
Open the Collections page from the left-hand menu.
Click on New.
Choose a name for the new Collection.
You may also include tags if needed by choosing tags from the drop-down that will open as soon as you click on the field or by typing a new value and pressing Enter.
Click Ok.
It might be needed to replace or change the key that is associated with a Collection from time to time. To replace a key with a new one, follow the steps below:
Open the Collections page from the left-hand menu.
Select the Collection from the list.
Click on Revoke Key.
Confirm that you would like to revoke the key. After clicking Revoke, the key will be replaced with a new key.
To remove a Collection, follow the steps below:
Open the Collections page from the left-hand menu.
Select the Collection you would like to remove.
Click on the Delete button.
4. Confirm that you would like to delete the selected Collection.
