Pull Request Overview

This PR adds checkpoint handling support for undelivered events in the DQ compute actor. Previously, when an unexpected event undelivery occurred and checkpoints were enabled, the actor would only log the undelivered event. Now, if checkpoints are available, undelivered events are forwarded to the checkpoint handler for proper management.

• Forward undelivered events to the Checkpoints actor when checkpointing is enabled
• Only log unexpected undelivered events when checkpoints are not available
