Does Oracle or AWS allow to configure separate propagation delays for insert/update/delete operations?

Not that I've ever heard of. Why would that be a good thing?

In the past, and I presume going forward, committing DML with the least delay has always been the strength of Oracle's two-phase transaction accuracy. Without knowledge of "upcoming features", then my answer is no.

I am assuming that you are talking about data replication here because you mentioned "propagation delays"

If so then yes it is possible but has a limited scope

For example : If source and target are Oracle and you are still using streams then set up a downstream environment. Replication will be archive based and that is all you going to get for lag. Please note that streams are not supported 11g onwards.

Set up data guard with ARCHIVE based service that again will give scope to introduce delays on the same ground.

If you are using a replication tool for example shareplex then stop the poster for designated time. This approach is little more configurable.

When it comes to Amazon , if using EC2 in my opinion all above should apply but if it is the case of RDS I am not sure if that would be possible.

The average business loses $13.5M per year to ineffective training (per 1,000 employees). Keep ahead of the competition and combine in-person quality with online cost and flexibility by training with Linux Academy.

Incorrect.  It is still supported.  It has been deprecated in 12c but is still supported.

OTHO, cyber-33 did differentiate individual DML operations by their type. The insight about Streams is a good add, but my guess is the intent was to process inserts and deletes and updates at  different throughputs. <shrugs> We're going to have to wait on the author :)
