Background Processing Behavior
Hi Team,
Hope everyone doing good!
I would like to understand on the below points, please do provide some insights on the same.
1. What if the background nodes which are processing JS Activity, QP activity, Email and File listeners stopped suddenly. What will happen to the data that got stucked in between? How to handle this?
2. What if Kafka server was stopped suddenly ( which in turn pushing the message/pulling the message got stucked). How to handle this scenario?
Thanks,
Vignesh.
