[CHORE] why UpdateRouteTable add UnchangedTriggers

[bxjg1987]

UpdateRouteTable.HandleAsync(WorkflowTriggersIndexed notification, CancellationToken cancellationToken)
await routeTableUpdater.AddRoutesAsync(notification.IndexedWorkflowTriggers.UnchangedTriggers, cancellationToken);

but why add UnchangedTriggers?

Good question. When the application starts, it needs to populate the RouteTable with existing triggers. Otherwise, the route table would remain empty until the user publishes HTTP workflows. Leep in mind that the RoutTable is an in-memory lookup and does not have its own persistence,
