Answer: Enable the Pub/Sub subscription retain-acked-messages flag, Apply Pub/Sub Seek with a specific timestamp
To reprocess Pub/Sub messages from the last two days, enabling the `retain-acked-messages` flag is essential as it allows the subscription to retain acknowledged messages for a certain period, enabling replay with the seek operation. Using `Pub/Sub Seek` with a timestamp is the method to actually reset the subscription's cursor to a given timestamp or snapshot, allowing reprocessing from that point in time. These two actions together ensure the pipeline can access and reprocess the necessary messages.
