cassandra驱动是否有类似SocketOptions.DEFAULT_READ_TIMEOUT_MILLIS的写超时的参数？

我们在初始化连接的时候，没有retry策略，在初始化和cassandra集群的连接时，设置socketOption如下：

SocketOptions socketOptions = new SocketOptions();
socketOptions.setKeepAlive(configuration.isKeepAlive());
socketOptions.setConnectTimeoutMillis(configuration.getConnectTimeoutMillis());
socketOptions.setReadTimeoutMillis(configuration.getReadTimeoutMillis());

ReadTimeoutMillis这个设置是有效的。我们测试的过程是

1、建立和cassandra集群的连接

2、中断cassandra驱动所在的客户端和集群的网络，发生读取的请求

3、在ReadTimeoutMillis设置的超时时间左右会有超时的异常。

但是我没有找到类似 WriteTimeoutMillis的参数，当我们在中断网络之后，发生写入请求，这个超时时间有变化，一般在20s~30s之间。

我想知道有没有类似ReadTimeoutMillis的 WriteTimeoutMillis参数，可以再socketOption里面设置？

是的，它确实。 较旧的Java driver版本使用DEFAULT_CONNECT_TIMEOUT_MILLIS进行写入请求。

Yes, it does. The older versions of the Java driver use DEFAULT_CONNECT_TIMEOUT_MILLIS for write requests. Cheers!

我现在使用的cassandra驱动是 cassandra-driver-core-3.6.0-shaded.jar。

请问DEFAULT_CONNECT_TIMEOUT_MILLIS 是否也是作为这个版本的写入操作的超时呢？

是的，它确实。请参阅Java driver 3.6 SocketOptions API文档。

Yes, it does. See the Java driver 3.6 SocketOptions API doc. Cheers!
