Motivation
The
ExtensibleLoadManagerImplbehavior is not the same as the old LB, the old LB’s ownership will be empty when the broker starts.When
ExtensibleLoadManagerImplstarts, it may have some owners will be loaded into table view, and those ownerships will not trigger the bundle ownership listener, which may cause some issues, for example, the kop relies on the load event to load the offset topics.Modifications
Notify bundle ownership listener
onLoadevent when ServiceUnitState starts.Documentation
