/**
|
|
* This job is created when sending notifications to the target users. The purpose
|
|
* of this job is to delete older notifications when the number of notifications a
|
|
* user has is more than $wgEchoMaxUpdateCount, it does not make sense to have tons
|
|
* of notifications in the history while users wouldn't bother to click 'load more'
|
|
* like 100 times to see them. What we gain from this is we could run expensive
|
|
* queries otherwise that would requires adding index and data denormalization.
|
|
*
|
|
* The initial job contains multiple users, which will in turn have individual jobs
|
|
* queued for them.
