Ben O'Day updated CAMEL-3009:
-----------------------------
Attachment: camel-quartz-skip-missed-jobs-patch.txt
I've been looking into this a bit. I thought I could simply use Quartz's
misfire modes (via "trigger.misfireInstruction" parameter) to get the desired
behavior, but I couldn't get it to work for this case (I'll log this
separately).
So, here is a first pass at adding support for this. I added a parameter to
the Quartz endpoint definition called "skipMissedJobs". When set to "true",
the endpoint is configured to only execute the last missed run of a job (prior
runs are skipped entirely)...
Some more investigation/advanced tests are necessary. I've attached a
preliminary patch for comments before taking it any further...
> Add option to quartz consumer to ignore jobs being triggered due restarting

> Quartz scheduler may by default try to catch up if a quartz consumer has been
> stopped for a while.
> Then when its started it may trigger a series of jobs due they were supposed
> to be triggered if the consumer has been always running.
> We should make it easy to configure an option to tell Camel to ignore those
> jobs.
> For example if you have a trigger to run every 5th second. And you pause a
> consumer for 2 hours. You may not want quartz to fire 12 * 60 * 2 jobs when
> its started to catch up for those 2 hours.
> Quartz itself may have an option you can configure on the job but it may not
> be obviously how to do this.
