Examples of AggregateProcessor

org.apache.camel.processor.aggregate.AggregateProcessor
.apache.org/aggregator2.html">Aggregator pattern where a batch of messages are processed (up to a maximum amount or until some timeout is reached) and messages for the same correlation key are combined together using some kind of {@link AggregationStrategy}(by default the latest message is used) to compress many message exchanges into a smaller number of exchanges.
A good example of this is stock market data; you may be receiving 30,000 messages/second and you may want to throttle it right down so that multiple messages for the same stock are combined (or just the latest message is used and older prices are discarded). Another idea is to combine line item messages together into a single invoice message.
