All Implemented Interfaces:

ServiceStatus.ServiceStatusCallback

Enclosing class:

ServiceStatus

public static class ServiceStatus.RealtimeConsumptionCatchupServiceStatusCallback
extends Object
implements ServiceStatus.ServiceStatusCallback

Service status callback that checks whether realtime consumption has caught up An offset based consumption status checker is being added in two phases. First phase adds the new status checker, but it doesn't apply its output. Instead it only logs its behavior. When the behavior is analysed and approved for different tables with different consumption rates, we can safely use the new status checker. (Another approach would be to define a new config and disable it by default. Since this feature is not urgent, we decided to not define yet another config and go with this two phase approach)
