The Hazelcast Module support (RateLimiter)[] interfaces.

Usage

Basic Synchronous Example

    import com.hazelcast.core.Hazelcast;
    import es.moki.ratelimitj.core.LimitRule;

    Hazelcast hz = Hazelcast.newHazelcastInstance();
    Set<RequestLimitRule> rules = Collections.singleton(RequestLimitRule.of(Duration.ofMinutes(1), 50)); // 50 request per minute, per key
    RequestRateLimiter requestRateLimiter = new HazelcastSlidingWindowRequestRateLimiter(hz, rules);
    
    boolean overLimit = requestRateLimiter.overLimit("ip:127.0.0.2");
