Hello Lorrin!
Claus explain this in his book Camel in Action (

following examples:
http://code.google.com/p/camelinaction/source/browse/#svn/trunk/chapter8/aggregator/src/test/java/camelinact
When using .split and .aggregate, what determines whether the aggregation is
performed across the messages that were split out from a single original
exchange vs. across messages that might have come from multiple original
exchanges?
I think the examples at http://camel.apache.org/splitter.html
