updateStreamGroup

Updates the configuration settings for an Amazon GameLift Streams stream group resource. You can change the description, the set of locations, and the requested capacity of a stream group per location. If you want to change the stream class, create a new stream group.

Stream capacity represents the number of concurrent streams that can be active at a time. You set stream capacity per location, per stream group. There are two types of capacity, always-on and on-demand:

• Always-on: The streaming capacity that is allocated and ready to handle stream requests without delay. You pay for this capacity whether it's in use or not. Best for quickest time from streaming request to streaming session.

• On-demand: The streaming capacity that Amazon GameLift Streams can allocate in response to stream requests, and then de-allocate when the session has terminated. This offers a cost control measure at the expense of a greater startup time (typically under 5 minutes).

To update a stream group, specify the stream group's Amazon Resource Name (ARN) and provide the new values. If the request is successful, Amazon GameLift Streams returns the complete updated metadata for the stream group.
