*** Bug 61148 has been marked as a duplicate of this bug. ***

It'd be nice to be able to register a job to execute after a certain amount of
time. My particular use case revolves around Elasticsearch's refresh interval:
once you push something to it you have to wait a second before you can query
that new data. Since we use Elasticsearch to count links we'd like to be sure
that updates that we just performed have hit the index.

Merging the bug I just filed with this one as they are pretty much the same. I will, though, bump the priority because my use case is not hypothetical.

Looks like JobQueueRedis supports a "jobReleaseTimestamp" timestamp. I'll play with it.

OK, so three things:

1. You have to turn it on even if you are using the redis job queue: $wgJobTypeConf['default'] = array( 'class' => 'JobQueueRedis', 'order' => 'fifo', 'redisServer' => 'localhost', 'checkDelay' => true, 'redisConfig' => array( 'password' => $wgRedisPassword, ), );

2. If you try to use 'jobReleaseTimestamp' when it isn't on you'll get an error. So if you want to optionally use it, you need something like this:

$jobQueueGroup = JobQueueGroup::singleton();
$jobQueue = $jobQueueGroup->get( 'cirrusSearchLinksUpdateSecondary' );
if ( $jobQueue->delayedJobsEnabled() ) {

		$params[ 'jobReleaseTimestamp' ] = time() + 60;

}

3. WMF doesn't have this on right now. I wonder why.
