Leaky buckets provide a clock-like model for software admission control
The piece connects leaky-bucket admission control to water clocks, where a steady outflow measures time and regulates when work can proceed. The model gives engineers a useful way to reason about gating actions when resources or priorities are constrained.
- What
- Leaky buckets are admission-control mechanisms that meter or queue incoming software work.
- How
- Work is accepted when bucket capacity allows; the bucket drains at a time-based rate, independent of task completion.
- Why it matters
- Meter-style buckets can reject work before execution to help keep systems healthy, including queries competing for database resources.
