Ignore "old" events on Operator startup

[agardnerIT]

Is it possible to NOT receive events for events older than the startup time. I don't want to "replay" any old events.

The best solution I've come up with so far is:

if event['type'] is None:
  print("Old event. Do not process")
  return

Kopf passes the events from Kubernetes to handlers as is. People might rely on that.

If you do not need some events, you can add the when= callback filter with the condition from your code snippet, and these events will be invisible to handlers (even no logs will be issued).

To wrap this up, based on the above feedback, I implemented it like this:

@kopf.on.event(
    'pods',
    annotations={"tracepusher/ignore": kopf.ABSENT},
    when=kopf.all_([is_new_event, is_pod_spawned_by_job, has_no_finalizers]))
def on_update_pod(event, spec, name, namespace, logger, **kwargs):
