Camel 3.18.3
Yes, I am talking about the onCompletion method of the AggregationStrategy.
So when I define the Splitter, I do define the AggregationStrategy class, and
in this class it should be possible that the method onCompletion is called.
But where I can define the options to the AggregationStrategy, I mean the
completionSize, completionInterval or completionTimeout?
