I need to get the count of process instances that meet a certain filter. The number may be a few thousand. Is there an api call that can return just the count? I am using queryProcessInstances() with a threshold of 1000 items at a time in a utility script, and I need a way to know how many there are so I can loop thru the appropriote number of times.

You certainly can with 3.6 there are new methods against the Execution Service. For each query there is now a ...ResultSize() method that can be called. For instance:

Code:

queryActivityInstanceNotifications(...)
queryActivityInstanceNotificationsResultSize()

Prior to 3.6 there is no way to do this directly with the API
