[Phoenix 基本配置]--链接配置选项

背景：

       今天在链接phoenix，使用delete语句删除表内容时，报了如下错误。

查看官方说明，发现需要在获取链接时修改默认的值，避免出现错误。

解决如下：

代码实现
Properties connectionProperties = new Properties();
connectionProperties.setProperty(QueryServices.MAX_MUTATION_SIZE_ATTRIB," 10000000 "); //改变默认的500000
connectionProperties.setProperty(QueryServices.IMMUTABLE_ROWS_ATTRIB," 10000000 "); // 默认是500000
connection = DriverManager.getConnection("jdbc:phoenix:ulvdtlchd01:2181",connectionProperties);

从而引出了org.apache.phoenix.query.QueryServices.java这个类，内容如下：
