[jboss-jira] [JBoss JIRA] (JGRP-1540) TP: simplified message bundler

TP: simplified message bundler ------------------------------ Key: JGRP-1540 URL: https://issues.jboss.org/browse/JGRP-1540 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.3 Instead of maintaining a hashmap (like for the current bundlers), a simple blocking bounded queue of messages would be used. Whenever we've reached M bytes or N milliseconds have elapsed, a consumer thread processes the queue in the following manner: * First set the queue to a new queue (volatile assignment), reuse a number of queues * Iterate through all messages in the current queue, for each message: ** If the destination is the same as the current destination, write the message to the stream for the current destination ** Else set the current destination to msg.getDest() and create an output stream (similar to writing a message list) *** Stream the current message to the output stream *** If there was a previous destination, close the associated output stream and send the message list Example: * We have messages with the following destinations: A, null, null, B, B, null, A, null, null, null * First we send a message list consisting of 1 message to A * Next we send a message list consisting of 2 messages to the cluster (dest==null) * Then we send a batch of 2 messages to B, 1 to the cluster, 1 to A and 3 to the cluster
