special delay
Hello, i would like to know if that is possible in Camel to consumer with
an initial delay but not have a delay after every message. If that is not
clear, here is a picture of what is would like:

Hi
Yeah it would be component specific if they have such a delay, for
example timer, quartz, scheduler etc has such thing.
But what you are asking for seems like to start routes delayed. At
this moment this is not supported generic. But as Ralf says you can
use a RoutePolicy and then manually start the route later. Or have
some thread that triggers after X time and start the routes you need
to start later.
What is your use case for such feature btw ?

Hello Joseph,
if the Consumer does not support the delay you can use a RoutePolicy to
defer the actual route start:
from("timer:hello")
.routeId("hello")
.routePolicy(new RoutePolicySupport() {
@Override public void onInit(Route route) {
super.onInit(route); final Runnable starter = () -> {
try {
final int millis =5000; log.info(String.format("Starting route %s after %d milliseconds", route.getId(), millis)); Thread.sleep(millis); startRoute(route); }catch (Exception e) {
handleException(e); }
}; route.getRouteContext().getCamelContext()
.getExecutorServiceManager()
.newThread("DelayRouteStart", starter)
.start(); }
}
)
.noAutoStartup()
.log("Hello from Timer");
Notice that the route needs noAutoStartup().
