On a GridGain cluster, you sometimes want to execute your jobs on only a subset of the nodes available: those nodes meeting a given condition. Let’s say some nodes run an expensive piece of thirdparty software that is (fortunately) only needed for a couple of tasks. At another time, the jobs should be executed on a different subset, or maybe on all nodes of the cluster.
