- 优点：
支持任意时间的延迟消息
任意延迟消息不到期不会删除
rocketmq原有的所有优点
- 缺点：
commitlog、comsumequeue文件空间浪费
不支持DLedger 模式
rocketmq原有的所有缺点
- 可配置项：
//任意延迟消息属性配置
//commitLog路径
anyDelayStorePathCommitLog =G:\\BaiduNetdiskWorkspace\\temp\\rocketmq\\dataDir\\dataDir\\anydelaycommitlog
//消息队列存储路径
anyDelaystorePathConsumeQueue =G:\\BaiduNetdiskWorkspace\\temp\\rocketmq\\dataDir\\dataDir\\anydelayconsumequeue
//任意延迟消息保留时间，指的是到达延迟时间后再经过多少天才删除
anyDelayfileReservedTime = 48
- 使用方法：
//注：跟message.setDelayTimeLevel();冲突
Message message = new Message("my_topic", "Hello RocketMQ".getBytes());
//指定11秒后到期
message.setDelayTimeStamp(11000);
//or 指定11秒后到期
//message.setFixTimeStamp(System.currentTimeMillis()+11000);
Apache RocketMQ is a distributed messaging and streaming platform with low latency, high performance and reliability, trillion-level capacity and flexible scalability.
It offers a variety of features:
- Messaging patterns including publish/subscribe, request/reply and streaming
- Financial grade transactional message
- Built-in fault tolerance and high availability configuration options base on DLedger
- A variety of cross language clients, such as Java, C/C++, Python, Go, Node.js
- Pluggable transport protocols, such as TCP, SSL, AIO
- Built-in message tracing capability, also support opentracing
- Versatile big-data and streaming ecosytem integration
- Message retroactivity by time or offset
- Reliable FIFO and strict ordered messaging in the same queue
- Efficient pull and push consumption model
- Million-level message accumulation capacity in a single queue
- Multiple messaging protocols like JMS and OpenMessaging
- Flexible distributed scale-out deployment architecture
- Lightning-fast batch message exchange system
- Various message filter mechanics such as SQL and Tag
- Docker images for isolated testing and cloud isolated clusters
- Feature-rich administrative dashboard for configuration, metrics and monitoring
- Authentication and authorization
- Free open source connectors, for both sources and sinks
