Innovabit.DotNet.Interceptors.RateLimiting.Redis

Redis store for Innovabit.DotNet.Interceptors.RateLimiting.Abstractions: the allowance is shared, so [RateLimit(PermitLimit = 100)] means a hundred calls across your whole service, not a hundred per instance.

Usage

services.AddSingleton<IConnectionMultiplexer>(_ => ConnectionMultiplexer.Connect("localhost:6379"));

services
    .AddInterceptors()
    .AddRedisRateLimiter();                              // or .AddRedisRateLimiter("localhost:6379")

services.AddInterceptors().AddRedisRateLimiter(o =>
{
    o.KeyPrefix = "contoso:rl:";   // keep two applications on one Redis out of each other's counters
    o.FailOpen = false;            // refuse rather than let calls through when Redis is unreachable
});

How it counts

A fixed window: one counter per partition per window, with the window's start baked into the key. INCR and the expiry happen in a single Lua script, so they are one round trip and one atomic step — two calls would leave a key without a TTL whenever the process died in between, and that allowance would never reset. A new window starts with a fresh key and the old one expires on its own, so there is no reset step and nothing to clean up.

A fixed window is the cheapest correct-enough choice. Its known edge is the boundary: a caller can spend the whole allowance at the end of one window and again at the start of the next, so twice the limit can pass within a window's length. A sliding-log or token-bucket limiter avoids that at the cost of storing every timestamp; if the boundary matters more than the cost, write a store that does.

When Redis is unreachable

By default the call goes through. A rate limiter exists to protect you from too much traffic, and taking the service down entirely because the limiter is unavailable trades a degraded service for no service at all.

Set FailOpen = false when the limit is a contractual quota rather than self-protection, and exceeding it is worse than refusing the call.
