final class PhabricatorMetronome
Phorge Technical Documentation ()

Tick at a given frequency with a specifiable offset.

One use case for this is to flatten out load spikes caused by periodic service calls. Give each host a metronome that ticks at the same frequency, but with different offsets. Then, have hosts make service calls only after their metronome ticks. This spreads service calls out evenly more quickly and more predictably than adding random jitter.
