Is there a limit on it and is the limit configurable?

There is a hard limit of 145 active execution contexts on a Cluster. This is to ensure the cluster is not overloaded with too many parallel threads starving for resources.

The limit is not configurable. If there are more than 145 parallel jobs to be executed, its strongly recommended to create a new cluster

Is it depend on the cluster size? If yes, what is the appropriate cluster configuration we are talking here.
