Java Spring Cassandra超时查询“从system_schema.tables中选择*”在PT2S后超时

我使用SpringBoot2.4.4和SpringDataCassandra依赖项连接到Cassandra数据库。在应用程序启动期间，我在使用VPN时遇到DriverTimeout错误

我已经看过了所有类似的堆栈溢出问题，没有一个对我有用。我在弹簧靴上交叉张贴了相同的问题

我使用了下面的配置属性-

spring.data.cassandra.contact-points=xxxxxx
spring.data.cassandra.username=xxxx
spring.data.cassandra.password=xxxxx
spring.data.cassandra.keyspace-name=xxxx
spring.data.cassandra.port=9042
spring.data.cassandra.schema-action=NONE
spring.data.cassandra.local-datacenter=mydc
spring.data.cassandra.connection.connect-timeout=PT10S
spring.data.cassandra.connection.init-query-timeout=PT20S
spring.data.cassandra.request.timeout=PT10S

我还在application.properties中添加了DataStax属性，以检查它们是否可以从那里获取

datastax-java-driver.basic.request.timeout = 10 seconds
datastax-java-driver.advanced.connection.init-query-timeout = 10 seconds
datastax-java-driver.advanced.control-connection.timeout = 10 seconds

下面是我在帖子中建议使用的配置-

但我还是犯了同样的错误

Caused by: com.datastax.oss.driver.api.core.DriverTimeoutException: query 'SELECT * FROM system_schema.tables' timed out after PT2S

我还尝试了不同的方法，比如创建自定义CqlSessionFactoryBean，并以编程方式提供所有要覆盖的DataStax属性-

@EnableCassandraRepositories
public class CassandraConfig extends AbstractCassandraConfiguration { 

    @Bean(name = "session")
        @Primary
        public CqlSessionFactoryBean cassandraSession() {
            CqlSessionFactoryBean factory = new CqlSessionFactoryBean();
            factory.setUsername(userName);
            factory.setPassword(password);
            factory.setPort(port);
            factory.setKeyspaceName(keyspaceName);
            factory.setContactPoints(contactPoints);
            factory.setLocalDatacenter(dataCenter);
            factory.setSessionBuilderConfigurer(getSessionBuilderConfigurer()); // my session builder configurer 
            return factory;
        }
    // And provided my own SessionBuilder Configurer like below
    
    protected SessionBuilderConfigurer getSessionBuilderConfigurer() {
        return new SessionBuilderConfigurer() {
    
            @Override
            public CqlSessionBuilder configure(CqlSessionBuilder cqlSessionBuilder) {
                ProgrammaticDriverConfigLoaderBuilder config = DriverConfigLoader.programmaticBuilder()
                        .withDuration(DefaultDriverOption.CONNECTION_INIT_QUERY_TIMEOUT, Duration.ofSeconds(30))
                        .withBoolean(DefaultDriverOption.RECONNECT_ON_INIT, true)
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofSeconds(30))
                        .withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT, Duration.ofSeconds(20));
                return cqlSessionBuilder.withAuthCredentials(userName, password).withConfigLoader(config.build());
            }
        };
      }
}

同样的错误也不起作用。此外，我还排除了Cassandra自动配置类，如StackOverflow上建议的

我还尝试自定义自定义会话生成器，如下面所示，以查看是否可以工作-

@Bean
public CqlSessionBuilderCustomizer cqlSessionBuilderCustomizer() {
        return cqlSessionBuilder -> cqlSessionBuilder.withAuthCredentials(userName, password)
                .withConfigLoader(DriverConfigLoader.programmaticBuilder()
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofMillis(15000))
                        .withDuration(DefaultDriverOption.CONNECTION_INIT_QUERY_TIMEOUT, Duration.ofSeconds(30))
                        .withBoolean(DefaultDriverOption.RECONNECT_ON_INIT, true)
                        .withDuration(DefaultDriverOption.REQUEST_TIMEOUT, Duration.ofSeconds(30))
                        .withDuration(DefaultDriverOption.CONTROL_CONNECTION_TIMEOUT, Duration.ofSeconds(20)).build());
    }

还是不走运

不仅如此，我还按照建议添加了application.conf文件，将其放在类路径上，即使该文件在犯语法错误后被解析，我也知道它正在被读取。它不起作用

application.conf-

datastax-java-driver {
 basic.request.timeout = 10 seconds
 advanced.connection.init-query-timeout = 10 seconds
 advanced.control-connection.timeout = 10 seconds
}

我还将Spring引导版本切换到2.5.0.M3，以查看属性文件是否正常工作。我已经把我的项目推进了

使现代化 根据评论，我正在粘贴我的整个堆栈跟踪。而且，这种情况并非总是发生，有时有效，有时无效。我需要覆盖从PT2S到PT10S的超时或其他

当驱动程序没有从协调器节点获得回复时，将抛出DriverTimeoutException。它使用2秒的基本请求超时默认值：

datastax-java-driver {
  basic.request {
    timeout = 2 seconds

超时时间为2秒这一事实意味着没有任何覆盖被拾取，但我还没有完全弄清楚原因

更重要的是，读或写超时异常是另一种错误，当没有足够的副本响应以满足所需的一致性级别时，会发生这种异常-在这两种情况中，协调器都会向驱动程序回复异常

根据我的经验，DriverTimeoutException是由无响应节点和/或b重载协调器引起的

---

如果应用程序正在运行一个昂贵的查询，这可能是协调器没有及时响应的原因。在这种情况下，您需要解决的问题不是覆盖不起作用，因为在Cassandra术语中，2秒对于应用程序请求来说是永恒的-您需要确保您的集群没有过载，而这正是您需要解决的问题。干杯

所以我在这里看到了两种可能性

这个问题最有趣的部分。。。 …是SELECT语句：

SELECT * FROM system_schema.tables

system_模式的键空间定义如下：

这是简单拓扑还是网络拓扑？如果是这样的话，那可能会导致超时，特别是

我认为，system_模式键空间对于较新版本的Cassandra 2.2+来说是新的。您是否可能正在使用旧版本？ 基本上，确保system_模式设置了相应的默认复制。另外，请确保使用已知可用于您的Cassandra版本的Spring Data Cassandra版本

---

此外，我建议您在没有Spring数据的情况下尝试此功能。我很好奇，看看这与仅仅使用纯DS Java驱动程序之间是否有什么区别。

我在这里回答我自己的问题，以完成这一点，并让其他人知道我是如何解决这个特定问题的

我使用的是Spring Boot 2.4.5。当我升级到2.3+以后的版本时，我开始面临这个超时问题

根据我在这个问题上的经验，以下是我的发现

不管您在application.properties或application.conf中提供了什么超时，它们都会以某种方式被spring引导覆盖，或者可能会从DataStax驱动程序中选择默认值

甚至在SpringBoot官方项目中也产生了一个问题来处理这个问题。检查后来在2.5.0.M1版本中得到了修复

当我将此作为VM参数传递时，我的问题得到了解决

 $java -Ddatastax-java-driver.basic.request.timeout="15 seconds" application.jar

我通过了其他参数，如advanced.control-connection.timeout，因为有人建议我在不同的论坛上使用，但这对我不起作用。检查参考手册中的其他配置参数

我只在本地收到这个错误，所以我在EclipseVM参数中传递了这个错误，然后我再也没有看到这个错误了

此外，如果我将此时间减少到7-8秒，有时我会再次看到该错误。似乎不管您传递了什么超时值，异常消息都是硬编码的。这是我的观察

---

尝试创建一个bean，如下所示，然后尝试：

  @Bean
    public DriverConfigLoaderBuilderCustomizer defaultProfile(){
        return builder -> builder.withString(DefaultDriverOption.METADATA_SCHEMA_REQUEST_TIMEOUT, "3 seconds").build();
    }

或

您配置了spring.data.cassandra。

---

connection.init query timeout=PT20S，但错误消息提到PT2S。这是打字错误吗？您是否排除了网络问题，即检查与nc或类似设备的连接？我会在应用程序运行时，在超时发生之前检查netstat-nt输出。超时的完整堆栈跟踪是什么？从错误消息中不清楚超时发生的时间。这可能是您试图解决问题的副作用，但在当前的形式下，您的项目主要是配置Cassandra本身。这意味着Spring Boot的自动配置在很大程度上已经退出。因此，除非您在自己的代码中使用spring.data.cassandra.*属性，否则您设置的任何属性都不会产生任何效果。您是否能够从运行代码的计算机连接到cassandra？@Rajeev我面临着完全相同的问题。想检查您是否尝试直接使用datastax Java driver 4.5+&如果是，它对您有用吗？谢谢，Erick，我已经阅读了您提供的所有文档和建议。但问题是我无法控制Cassandra节点使其响应，为了使其工作，我必须增加请求超时。我没有其他选择。谢谢你的回答。@Rajeev，Erick是对的。延长超时时间并没有什么好处。@Aaron，是的。我对此毫无疑问，但我在本地笔记本电脑上使用VPN，这对我和我的团队来说会发生很多次。此外，当应用程序的负载增加时，我们将应用程序扩展到n个吊舱。如果Cassandra忙于向已经运行的吊舱提供大量请求，那么如果Cassandra在2秒内无法响应，则新的吊舱启动可能会失败，我试图增加至少5秒来避免这种情况。我使用的是Cassandra 3.11。如果我尝试重新启动应用程序，它只会在启动时失败10次中的7次。一旦连接起来，一切都会好起来。“我在试着看看是否能避免启动失败。”拉吉耶夫说。也许在没有Spring数据的情况下试试这个，看看结果是否有什么不同？好的，我会照你说的做。谢谢，Aaron。请花点时间学习这里的代码格式化工具-我们使用Markdown。编辑器中提供了联机帮助。
