RateLimitJ
A Java library for rate limiting, assembled using extensible storage and application framework adaptors. The library's interfaces support thread-safe sync, async, and reactive usage patterns.
Modules
RateLimitJ provides the following stable plugable modules:
Features
- Uses an efficient approximated sliding window algorithm for rate limiting
- Multiple limit rules per instance
Binaries/Download
Binaries and dependency information for Maven, Ivy, Gradle and others can be found at Maven Central.
Example for Maven:
<dependency>
<groupId>es.moki.ratelimitj</groupId>
<artifactId>ratelimitj-redis</artifactId>
<version>${ratelimitj-redis.version}</version>
</dependency>Prerequisite
- RateLimitJ requires Java 8
Roadmap
| Feature | Status |
|---|---|
| Redis sliding window rate limiter | production |
| Dropwizard integration - Bundle | production |
| In-memory sliding window rate limiter | stable |
| In-memory concurrent rate limiter | beta |
| Rate limiting toggles (dark launch) for framework integration | beta |
| Hazelcast sliding window rate limiter | beta/dev |
| Redis concurrent rate limiter | dev/active |
| Enhanced metrics logging | back log |
| Whitelisting & blacklisting of keys | back log |
| Rate limit HTTP header responses | back log |
| Async in-memory rate limit buffer/cache (inspired by Google's SRE book) | back log |
| Spring integration | back log |
Building
RateLimitJ is built with Gradle and requires docker to spin up Redis for the Redis module.
To build:
$ git clone https://github.com/mokies/ratelimitj.git
$ cd ratelimij/
$ ./gradlew
