是的，Java驱动程序的4.x版本与Cassandra 3.0和3.11集群兼容。
有关详情，请参阅Java驱动程序兼容性矩阵。
在不了解您面临的问题细节的情况下，我最好的猜测是您的集群负载过重，导致超时异常。祝好运！
英文:
Yes, version 4.x of the Java drivers are compatible with Cassandra 3.0 and 3.11 clusters.
For details, see the Java driver compatibility matrix.
Without knowing details of the issue you are facing, my best guess is that your cluster is overloaded leading to the timeout exceptions. Cheers!
