[Java] Class BrooklynGarbageCollector

java.lang.Object
  brooklyn.management.internal.BrooklynGarbageCollector

public class BrooklynGarbageCollector

Deletes record of old tasks, to prevent space leaks and the eating up of more and more memory. The deletion policy is configurable:

Period - how frequently to look at the existing tasks to delete some, if required
Max tasks per tag - the maximum number of tasks to be kept for a given tag (e.g. for effector calls invoked on a particular entity)
Max task age - the time after which a completed task will be automatically deleted (i.e. any task completed more than maxTaskAge+period milliseconds ago will definitely be deleted.

The default is to check with a period of one minute, to keep at most 100 tasks per tag, and to delete old completed tasks after one day.
