Doorman is a Go-based gRPC service for global distributed client-side rate limiting, letting clients voluntarily limit their use of shared resources like databases or APIs. It apportions capacity fairly via configurable algorithms, granting time-limited leases and using etcd as a distributed lock manager for high availability.

Use cases

• rate limit clients accessing a shared database across the globe
• distribute API quota fairly among many client applications
• prevent a gRPC service from being overwhelmed by its callers
• coordinate client-side throttling with leases and refresh intervals
• apportion capacity of a shared resource based on fairness algorithms

When to choose

• you need cooperative, globally coordinated client-side rate limiting
• your clients can honour capacity grants and refresh leases
• you already run etcd or a distributed lock manager
• you want configurable fairness algorithms for capacity apportionment

When to avoid

• you need to enforce limits against misbehaving clients (Doorman is cooperative only)
• you want simple per-instance rate limiting without a distributed setup
• you need a actively developed project with recent releases
• you cannot operate a gRPC service and distributed lock manager
