java - Astyanax 不遵守配置的套接字超时

Question

这是我的设置:

• 4 个节点 Cassandra 1.2.19
• Astyanax 1.56.49

我正在设置配置

AstyanaxContext<Keyspace> context = new AstyanaxContext.Builder()
    .forCluster(service.getClusterName())
    .forKeyspace(service.getKeySpaceName())
    .withAstyanaxConfiguration(new AstyanaxConfigurationImpl()
         .setDiscoveryType(NodeDiscoveryType.NONE)
         .setCqlVersion("3.0.0")
         .setDefaultReadConsistencyLevel(consistencyLevel.getAstyanaxValue())
         .setDefaultWriteConsistencyLevel(consistencyLevel.getAstyanaxValue())
    )
    .withConnectionPoolConfiguration(new ConnectionPoolConfigurationImpl("b2bConnectionPool")
         .setPort(service.getPort())
         .setMaxConnsPerHost(5)
         .setSeeds(StringUtils.join(hosts, ","))
         // increase default timeout for heavy operations (milliseconds)
         .setSocketTimeout(15000)
         .setSSLConnectionContext(sslContext)
         .setAuthenticationCredentials(credentials)
    )
    .withConnectionPoolMonitor(new CountingConnectionPoolMonitor())
    .buildKeyspace(ThriftFamilyFactory.getInstance());

现在有一个可重现的查询需要很长时间，最后抛出一个OperationTimeoutException:

com.netflix.astyanax.connectionpool.exceptions.OperationTimeoutException: OperationTimeoutException: [host=myhost(myip):13260, latency=10001(40007), attempts=4]TimedOutException()

异常消息显示“latency=10001”，我认为这应该是配置为 15000 毫秒的套接字超时，但显然不是。如何增加 astyanax 中查询操作的超时时间？

Answer 1

在尝试查询具有更大数据的节点时，我遇到了类似的超时异常。我在 cassandra.yaml 中修改了这 4 个值，它解决了所有超时错误。

协调器应等待读操作完成多长时间read_request_timeout_in_ms: 15000

协调器应等待 seq 或索引扫描完成多长时间range_request_timeout_in_ms: 30000

协调器应等待写入完成多长时间write_request_timeout_in_ms: 30000

协调器应等待计数器写入完成多长时间counter_write_request_timeout_in_ms: 15000

注意:您需要在集群中的所有节点中执行此操作，并且还需要在所有节点中重新启动 Cassandra。
