Putting back event for reprocessing after a specific amount of time

[csviri]

We should allow users to put back events for reprocessing, this will allow periodic checking / polling with a very generic way.

[csviri]

We will cover this functionality within this issue:
https://github.com/ContainerSolutions/java-operator-sdk/issues/179

Is the proposal here related to extending the UpdateControl class so that we could specify a time after which the event would be handled again?

Similarly to this: https://godoc.org/sigs.k8s.io/controller-runtime/pkg/reconcile#Result ?

[csviri]

@goldmann basically yes, the issue mentioned before will cover this, but with a slightly different approach.
In the first milestone we will just provide support for that, in next iterations, hopefully also nicer APIs.

@csviri Great, this is something I'm really interested in! I'll take a look at the PR.

@goldmann it's a quibe big PR, covering a lot. Will write a post that will serve as a introduction / documentation to it. Also feel free to jump on discord and ask question if needed.
