  ****************************************************************
  In some cases, the key contributor for the heap is not the
  sender.  When this happens, only a little amount of data in the
  biggest sender will be discarded for GC (Garbage Collection)
  using the current logic. CDP needs to adjust the heap management
  to prevent this kind of invalid discard of data.
  

Problem conclusion

• CDP v2.1 is updated to enhance the logic of heap management by
  adding a check of whether the sender is the key contributor of
  the heap or not, before discarding the data to enhance the GC
  efficiency of Data Streamer.
