Subject [jira] [Commented] (S4-9) Bypass comm layer when target PE is local
Date Sat, 15 Oct 2011 00:58:11 GMT

    [ https://issues.apache.org/jira/browse/S4-9?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13128009#comment-13128009
] 

Leo Neumeyer commented on S4-9:
-------------------------------

Implemented a solution for sending local events. Events sent to the local partition are no
loger sent over the comm layer. If the configuration has a single node, there will be no serialization
and the event is put in the local stream queue directly.

The challenge was to figure out how to make the sender know what its own partition was. For
now, I did this in App but it will have to be moved to Server because this should be a server-level
initialization.

> When the source and target PEs are local we should bypass the comm layer. The event should
be put in the local stream directly. Stream must be able to query a comm layer method such
as isLocal(). If true, the event is put in the local stream queue directly. This is an optimization.
