Question

我正在检查具有不同数量的主题发布者和订阅者的hazelcast群集的吞吐量。有2个发布者和2个订阅者一切正常。有3个发布商和1个订阅者，我发现订单问题：每个发布商的每100K事件我的订单不匹配2-10个事件。 Hazelcast版本：3.6.1

这是我的配置：

@Bean
public HazelcastInstance hazelcastInstance() {
    Config config = new Config();
    config.getGroupConfig().setName("test").setPassword("test");
    config.setTopicConfigs(getTopicConfigs());
    return Hazelcast.newHazelcastInstance(config);
}

private Map<String, TopicConfig> getTopicConfigs() {
    TopicConfig topicConfig = new TopicConfig(topicName);
    topicConfig.setStatisticsEnabled(false);
    return new HashMap<String, TopicConfig>(){{put(topicName,topicConfig);}};
}

@Profile("out")
@Bean
public ITopic<Event> eventsOutput(HazelcastInstance hazelcastInstance) {
    return hazelcastInstance.getTopic("events");
}

@Profile("in")
@Bean
public ITopic<Event> eventsInput(HazelcastInstance hazelcastInstance) {
    return hazelcastInstance.getTopic("events");
}

以下是日志的一部分：

等...

我可以认为问题出在我的代码中。但是： - 测试代码非常简单，无需任何额外的过程 - 订单不匹配的seq数量非常漂亮且可重复 - 只有当出版商数量从2增加到3时才会重现。

所以我想问题是使用hazelcast配置。看起来我错过了什么。我正在重读hazelcast规范，尝试了一些属性但没有成功。有人可以提示一下这个问题可能是什么来源？

会欣赏任何笔记。提前致谢。
