HammerBackendRedisCluster

A Redis Cluster backend for the Hammer rate-limiter.

Installation

Hammer-backend-redis-cluster can be installed by adding hammer_backend_redis_cluster to your list of dependencies in mix.exs, pointing to the proper GitHub repo:

def deps do
  [{:hammer_backend_redis_cluster, git: "https://github.com/stiang/hammer-backend-redis-cluster.git"},
   {:hammer, "~> 6.0"}]
end

Usage

Configure the :hammer application to use the Redis backend:

config :hammer,
  backend: {Hammer.Backend.RedisCluster, [expiry_ms: 60_000 * 60 * 2,
                                   redix_remastered_config: [host: "localhost",
                                                  port: 6379]]}

(the redix_remastered_config arg is a keyword-list which is passed to RedixCluster, it's also aliased to redis_remastered_config, with an s)

And that's it, calls to Hammer.check_rate/3 and so on will use Redis to store the rate-limit counters.
