public class GroupMetadataUpdateEvent extends BackgroundEvent
This event is sent by the consumer's network thread to the application thread so that when the user calls the Consumer.groupMetadata() API, the information is up-to-date. The information for the current state of the group member is managed on the consumer network thread and thus requires this interplay between threads.
