Execution of a flow before NR shutdown? I thought I saw a forum thread on this? But I can't seem to find it, so maybe this is not possible currently?
Since I am running a primary and secondary NR setup, not a cluster, no transparent fail-over type of thing. Just stop and start of services as applicable.
It would be nice to implement the graceful fail-over and recovery logic in NR as much as possible. But could just do it external to NR, since the non-graceful control will be external to NR anyway.
