如何为Cassandra创建连接池？

import com.datastax.driver.core.Cluster;
import com.datastax.driver.core.Session;

public class CassandraConnectionPoolExample {
    private static Cluster cluster;
    private static Session session;

    public static void main(String[] args) {
        // 配置连接池参数
        int maxConnections = 10;
        int minIdleConnections = 5;
        int connectTimeoutMillis = 5000;

        // 创建连接池对象
        cluster = Cluster.builder()
                .addContactPoint("cassandra-host")
                .withPort(9042)
                .withCredentials("username", "password")
                .withMaxConnectionsPerHost(maxConnections)
                .withMinIdleConnections(minIdleConnections)
                .withConnectTimeout(connectTimeoutMillis)
                .build();

        // 获取连接
        session = cluster.connect();

        // 执行数据库操作
        // ...

        // 释放连接
        session.close();
        cluster.close();
    }
}
