Sergey Zhemzhitsky commented on CAMEL-4928:
-------------------------------------------

New _async_ parameter has been added in the included patch.

{code:title=Sample}
from("timer:start?async=true")
    .threads(1, 5)
    .to("bean:very-long-operation")
{code}

So by default the behavior is exactly the same as in the previous version of 
timer and if one want to use asynchronous API _async=true_ parameter should be 
added in the endpoint uri.

The patch also includes _doSuspend_ and _doResume_ methods in the TimerConsumer 
to be able to stop the route faster and to prevent the timer running during 
stopping the route when using async. api.

> It would be great to have timer component support asynchronous API.
> Such a feature can be useful when timer component generates events which must 
> be processed by multiple threads. 
> Current implementation of the timer component makes a blocking call so the 
> usage of thread pools hardly possible to process multiple timer event 
> simultaneously.
