Q: How can I access the events which triggered the Reconciliation? #

In the v1.* version events were exposed to Reconciler (in v1 called ResourceController). This included events (Create, Update) of the custom resource, but also events produced by Event Sources. After long discussions also with developers of golang version (controller-runtime), we decided to remove access to these events. We already advocated to not use events in the reconciliation logic, since events can be lost. Instead reconcile all the resources on every execution of reconciliation. On first this might sound a little opinionated, but there was a sound agreement between the developers that this is the way to go.

Q: Can I re-schedule a reconciliation, possibly with a specific delay? #

Yes, this can be done using UpdateControl and DeleteControl , see:

  @Override
  public UpdateControl<MyCustomResource> reconcile(
     EventSourceTestCustomResource resource, Context context) {
    ...
    return UpdateControl.patchStatus(resource).rescheduleAfter(10, TimeUnit.SECONDS);
  }

without an update:

  @Override
  public UpdateControl<MyCustomResource> reconcile(
     EventSourceTestCustomResource resource, Context context) {
    ...
    return UpdateControl.<MyCustomResource>noUpdate().rescheduleAfter(10, TimeUnit.SECONDS);
  }

Although you might consider using EventSources, to handle reconciliation triggering in a smarter way.
