Hello, We use NiFi in cluster mode in Kubernetes via a StatefulSet. Sometimes, we need to restart the cluster, so the StatefulSet restarts one pod at a time. In this scenario, will a given node attempt to process all "in-flight" FlowFiles to drain the queues as much as possible before shutting down?
I know it's probably impossible to have a completely graceful offload in these cases, but since the process still receives a termination signal and has some time before it must stop, it could try to prevent FlowFiles from staying in the system for too long, but I don't know if there are any mechanisms to handle this in NiFi. Regards, Alexis.
