Say I have a
that deploys as a WAR and is deployed to multiple nodes. I deploy it to multiple nodes for high availability. The app uses Quartz to schedule certain jobs being kicked off. Let's say one of these jobs should only be ran once a day.
If I have the app deployed to 5 nodes, it will get ran 5 times a day, once on each node.
Do any mechanisms exist to orchestrate certain jobs things that should only run once in a distributed/clustered environment, and not by each app instance in the cluster?
I did find this article
but it seems to be a solution that is limited to one node:
Never run clustering on separate machines, unless their clocks are synchronized using some form of time-sync service...
