Global and Per-Tenant Rate Limiting
A rate limiter must enforce both a global cap and per-tenant caps. Why is a purely local counter insufficient?
Options
- 1Local counters simply cannot count requests accurately on a per-second basis, so they drift under load
- 2Local counters consume far too much durable disk space to be worth keeping on each individual instance
- 3With many instances, local counters let the aggregate exceed the intended global or tenant limit
- 4Local counters cannot be reset once the process has been running for a while without a full restart
