Rate Limit Token Bucket
Per-key token bucket rate limiter.
A MuxCore sidecar module that enforces per-key token-bucket limits via gRPC (Allow / Enabled). Provides the ratelimit / ratelimit.tokenbucket capability.
How It Works
Caller ──→ Allow(key) ──→ ratelimit-tokenbucket ──→ allow / deny
Each key gets its own bucket. Limiting is off until RATELIMIT_ENABLED is set.
Configuration
| Variable | Default | Description |
|---|---|---|
RATELIMIT_RATE |
100 |
Tokens replenished per second |
RATELIMIT_BURST |
200 |
Maximum bucket size |
RATELIMIT_ENABLED |
false |
Enable limiting (true / 1) |
Default gRPC listen address (code default, no env): :9800.
Quick Start
make build
export RATELIMIT_ENABLED=true
./ratelimit-tokenbucket --muxcore-mesh-addr localhost:9090
Capability
