Hi, You could definitely try to find formula for heap size, but isnt's it easier just to try out different memory settings and see which works best for you?

In the configuration section, it is mentioned that for "many operators" heap size should be increased. "JVM heap size (in megabytes) for the JobManager. You may have to increase the heap size for the JobManager if you are running very large applications (with many operators), or if you are keeping a long history of them." Is there any recommendation on the heap space required when there are around 200 CEP operators, and close 80 Filter operators? Any other leads on calculating the expected heap space allocation to start the job would be really helpful.
