             Summary: Allow specification of non-heap memory size
                 Key: APEXCORE-500
                 URL: https://issues.apache.org/jira/browse/APEXCORE-500
             Project: Apache Apex Core
          Issue Type: Improvement
            Reporter: Pramod Immaneni
            Assignee: Pramod Immaneni


Currently there are two mechanisms affecting the non-heap size none of which are direct. By default, it is 0.25 of the container size but max size limited to 1GB. The other way is when the heap memory is explicitly specified to a fixed value the remaining memory is available for non-heap. 

If a specific size is desired for non-heap that is greater than the default then they today the heap size has to be specified for each container. This size could change from container to container based on the operator it contains and the user has to calculate and set these heap sizes. Instead, it will be easier to have an option to directly specify one non-heap size.
