Hi

The timeout check is happening after your have added the exchange, so if =
you take 5 seconds to add the exchange, then Camel will check the =
timeout on next loop (BatchProcessor). So you should be home free, and =
not lose any messages ;)

See the source BatchProcessor.


However the default batch timeout is *only* 1 sec. So you should be fast =
to aggregate ;). I think most people must set a timeout value that fits =
their use-case.

Subject: Aggregator execution and timeout value


Hi all,

I have a question about aggregator behaviour and wish someone would help =
me.

Suppose my aggregationStrategy aggregate function is like that:

Class MyaggregationStrategy implements AggregationStrategy {

public Exchange aggregate(Exchange oldExchange, Exchange newExchange) {

		.. some longer process on oldExchange and newExchange...
	}

	...
}

What happened if during aggregate function execution, because of timeout =
(of
the aggregator) the polling of the endpoint linked to the aggregator
restart?

Did in process modification on oldExchange and/or newExchange are lost?=20

Any help are welcome,
Thanks in advance.
