<p>smartchart已实现大部分常用的数据源连接, 对于其它的, 您也可以使用python数据源进行处理
但是使用python数据源有一定的缺陷, 需要在dataset上写python代码, 不能复用
对于一些带连接信息的还需要重复写入
所以你还可以使用自定义数据源</p>

</h4>
<ul>
<li>未内置的数据源, 如需要使用sparkSQL, ES等</li>
<li>标准处理满足不了要求, 需要对数据进行预处理的情况</li>
<li>需要刷新时触发预警等自定义动作</li>
<li>需要自定义写入方法, 个性化查询需求, 甚至是实时爬取数据</li>

</h4>
<ul>
<li>首先你需要新建一个python脚本文件, 如diy_conn.py</li>
