Manage Collections
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.
Create a Collection
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.
Change a Collection key
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:
