Disallowing concurrent execution of a scheduler on clustered enviornment

We have a clustered environment with some schedulers (configured to run on UTC time), we would like to prevent running the same scheduler concurrently, is it possible to prevent that by disallowing concurrent execution of the related microflow? does this work on clustering?

Take a look at the answers to this question about high avaiolability architecture, in particular the parts about scheduled events.

In short, you should not have all scheduled events enabled on all nodes (as they run independently and are not aware of what another node is doing). You should either have them disabled on one node, or split the load between nodes by specifying where to run individual scheduled events
