I didn't see anything posted on this (though I may have missed it). I am
using Camel 2.7.0.
When using aggregate(), is there a default behavior? What I mean by this
is, let say you have the following Route in your RouteBUilder:
from("jms:queue:myQueue").aggregate().process(new
BatchSaveMessagesToDBProcessor());
Would the default behavior of Camel be to just create a List of whatever
objects are in Exchange.getIn().getBody()?
I noticed there are 4 different aggregate() methods:
aggregate()
aggregate(AggregationStrategy)
aggregate(Expression)
aggregate(Expression, AggregationStrategy)
Let's say all you want to do is batch up the messages coming in in order to
do a batch save to the DB; would you need to specify an AggregationStrategy
and/or Expression; or will Camel handle creating a List of what is in the
"In" message body?
What I have noticed is aggregate() and aggregate(AggregationStrategy) have a
different API than aggregate(Expression) and aggregate(Expression,
AggregationStrategy). Why the difference?
Thanks!
