我的临时处理方案是在. JsonNode 解析为 RowData 之前, 把 JsonNode 中的 data 和 old 做 lowercase 处理. 但这样会影响性能, 期待有更好的处理方法.

//对 root.data 中的所有字段lowercase处理.
      dataToLowerCase(root.get("data"));
//对 root.old 中的所有字段lowercase处理.
      dataToLowerCase(root.get("old"));

如果我忽略了什么配置项. 也请指出. 谢谢.

The column name in TiDB is case-insensitive.

We use TiDB native client to get columns which will return us a TiTableInfo object, and the column names in TiTableInfo is lowercase. That's why we need to convert the column name to lowercase. If we use mysql driver to get columns names, we can get original column names rather than lowercase. We need some time to think about how to fix it.
