Module rate_limits 

Admission-based rate limiting for throughput and bandwidth.

This module provides RateLimiter, which enforces configurable limits at three levels of granularity — global, per-usecase, and per-scope — for both request throughput (requests/s) and upload/download bandwidth (bytes/s).

Throughput is enforced using token buckets; bandwidth is estimated with an exponentially weighted moving average (EWMA) updated by a background task every 50 ms. All rate-limit checks are synchronous and non-blocking.

Structs

BandwidthLimits

Bandwidth limits applied at global, per-usecase, and per-scope granularity.

RateLimiter

Combined rate limiter that enforces both bandwidth and throughput limits.

RateLimits

Rate limits for objectstore.

ThroughputLimits

Request throughput limits applied at global, per-usecase, and per-scope granularity.

ThroughputRule

An override rule that applies a specific throughput limit to matching request contexts.
