+ +* **column** + + * 描述：目的表需要写入数据的字段,字段之间用英文逗号分隔。例如: "column": ["id", "name", "age"]。如果要依次写入全部列，使用`*`表示, 例如: `"column": ["*"]`。 + + **column配置项必须指定，不能留空！** + + 注意：1、我们强烈不推荐你这样配置，因为当你目的表字段个数、类型等有改动时，你的任务可能运行不正确或者失败 + 2、 column 不能配置任何常量值 + + * 必选：是

+ + * 所有选项：insert/replace/update
+ + * 默认值：replace
+ +* **batchSize** + + * 描述：一次性批量提交的记录数大小，该值可以极大减少DataX与 Adb MySQL 的网络交互次数，并提升整体吞吐量。但是该值设置过大可能会造成DataX运行进程OOM情况。
