I'm not sure what you mean exactly. If you don't want to sort
messages, you can use the default queue instead of SortedMessageQueue.

If you are talking about Graph package and ListVerticesInfo, it's my
temporary solution to fix a bug of memory-based vertices storage,
ListVerticesInfo[1]. Loaded vertices and Messages among graph task
processors, must be sorted to reduce memory consumption and GC
overheads (See https://issues.apache.org/jira/browse/HAMA-704).  If
you want to improve the memory-based vertices storage, Please feel
free to open the ticket on JIRA system.

of ArrayList?
