Extensions: $wgJobBackoffThrottling
Number of times work items of a job type can be run per second.
Introduced in version:1.23.0 (Gerrit change 103190; git #e8cb2073)
Removed in version:still in use
Allowed values:(number >= 0)
Default value:[]



Number of work items of a given job type to perform per second. What exactly a "work item" means is up to the job; it just has to return the number of them in Job::workItemCount(). For example, it could mean the number of pages updated for a job which does batch updates. However, this setting won't limit the number of pages updated in one job run (which is controlled by $wgUpdateRowsPerJob ). Instead, it will throttle new executions of that job type.

Whenever a job of the given type gets executed, no jobs of the same type will be started in the next ( work item count / backoff throttling ) seconds.

This only affects jobs started by maintenance/runJobs.php (as opposed to $wgJobRunRate which only affects job started by web requests).
