Using Kinesis streams to receive system messages

You can configure an AppInstance to receive data in the form of a stream. For example, a stream can include messages, sub-channel events, and channel events.

As part of that, we support the CREATE_SUB_CHANNEL and DELETE_SUB_CHANNEL events. They indicate when a sub-channel was created or deleted as part of membership balancing. For more information about receiving data streams, refer to Streaming messaging data.
