[jira] [Updated] (HAMA-568) Add faster synchronized collections for
message queues
[ https://issues.apache.org/jira/browse/HAMA-568?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mayank Mishra updated HAMA-568:
-------------------------------
Attachment: HAMA-568_2.patch
Added Map to map non synchronized to synchronized one (for only localQueueForNextIteration). DiskQueue and MemoryQueue still using SingleLockQueue, whereas SortMessageQueue is using PriorityBlockingQueue internally.

> Currently the synchronized messaging (accessed concurrently via RPC) is done with a single mutex object. See org.apache.hama.bsp.message.SynchronizedQueue.
> This can be improved for memory queue by adding the ConcurrentLinkedQueue from Java since it has higher throughput.
> Needless to say, we should add some custom synchronized version of a queue, maybe through a factory class in the normal version.
