RocketMq(rockmq-all 4.4.1-SNAPSHOT): 默认压缩大于4K的消息（可配置），压缩算法是zip，默认级别5（可配置），同样也是客户端做解压缩工作，服务端只存储；对于批量消息的压缩，目前并不支持。
摘取DefaultMQProducerImpl.java 部分源码：
private boolean tryToCompressMessage(final Message msg) {
        if (msg instanceof MessageBatch) {
            //batch dose not support compressing right now
            return false;
        }
        byte[] body = msg.getBody();
        if (body != null) {
            if (body.length >= this.defaultMQProducer.getCompressMsgBodyOverHowmuch()) {
                try {
                    byte[] data = UtilAll.compress(body, zipCompressLevel);
                    if (data != null) {
                        msg.setBody(data);
                        return true;
                    }
                } catch (IOException e) {
                    log.error("tryToCompressMessage exception", e);
                    log.warn(msg.toString());
                }
            }
        }

        return false;
    }
