[jira] [Created] (AURORA-1839) Improve SlotSizeCounter's memory footprint

Mehrdad Nurolahzade created AURORA-1839:
-------------------------------------------

             Summary: Improve SlotSizeCounter's memory footprint
                 Key: AURORA-1839
                 URL: https://issues.apache.org/jira/browse/AURORA-1839
             Project: Aurora
          Issue Type: Task
          Components: Efficiency
            Reporter: Mehrdad Nurolahzade
            Priority: Minor


{{SlotSizeCounter}} categorizes and counts the number of empty slots in the cluster using resources offers received from Mesos in order to exposes stats on them. Its current implementation is inefficient and generates lots of GC overhead (for example, due to unnecessary string concatenations) in large clusters with thousands of outstanding offers.
