GitHub user Susmit07 edited a discussion: Pekko Connector Fault Tolerance 
Processing

Hi Team,

I tested this functionality


- Prepare 2000 files in a test location local inside the pod
- Deploy the app on Kubernetes with multiple pods using the Cluster Singleton 
setup. Ensure that only one pod is processing files at a time. (which we 
achieved)
- While the first pod is processing files, kill the pod to simulate failure.
- Monitor the logs of the next pod that takes over. It should resume processing 
from the last processed file.

But actually its processing from the first one again, in other words no offset 
is maintained.

Does pekko out of the box supports exactly once or we need to maintain the 
state in a  PersistentVolumes  / DB like a key value store along with Pekko 
Persistence module

Awaiting response
