Introduced in GitLab 12.4.
Set the number of branches or tags to limit the number of single push events allowed at once. If the number of events is greater than this, GitLab creates bulk push event instead.
For example, if 4 branches are pushed and the limit is currently set to 3, the activity feed displays:
With this feature, when a single push includes a lot of changes (for example, 1,000 branches), only 1 bulk push event is created instead of 1,000 push events. This helps in maintaining good system performance and preventing spam on the activity feed.
This setting can be modified in Admin Area > Settings > Network > Performance Optimization.
This can also be configured via the Application settings API
push_event_activities_limit. The default value is 3, but it can be greater
than or equal 0.
