Papa John updated CAMEL-20357:
------------------------------
Description:
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}
