Otavio Rodolfo Piske commented on CAMEL-20357:
----------------------------------------------
Long story short: there was a change in behavior for the throttle EIP which is
more impactful that we originally thought. We are discussing that implications
of that change and what we can do to align the previous expectation / fix
behavior / etc.
> camel-core - throttle EIP doesn't work as expected when it's in a loopDoWhile

> Key: CAMEL-20357
> URL: https://issues.apache.org/jira/browse/CAMEL-20357
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 4.3.0
> Reporter: Papa John
> Assignee: Rhuan Rocha
> Priority: Minor
>
> I just upgraded my project to Apache Camel 4.3.0, and my code stop to work as
> expected.
> It seems there was some changes to the `throttle EIP` – it's now throttling
> based on the number of concurrent exchanges.
> My route uses a {{`{*}loopDoWhile{*}`}} to loop an exchange over and over, so
> in a sense, the concurrent exchange should always be zero (and the inflight
> exchange is actually zero).
> However, my loop will stop when it reached the max number of concurrent
> exchanges I set for the thottler.
> For example, in the following code, the loop will stop at 10th iteration. It
> seems the new changes didn't put loop DSL into consideration...
> {code:java}
> import org.apache.camel.builder.RouteBuilder;public class Test extends
> RouteBuilder { @Override
> public void configure() throws Exception { // Write your routes
> here, for example:
> from("timer:java?delay=1000&repeatCount=1")
> .loopDoWhile(constant(true)).breakOnShutdown()
> .throttle(10)
> .setBody()
> .simple("Hello Camel from ${routeId}")
> .log("${body}");
> }
> } {code}
