DataWorks MySQL Writer脚本开发介绍是什么？

脚本配置示例如下，使用脚本模式开发的详情请参见通过脚本模式配置任务。{"type":"job","version":"2.0",//版本号。"steps":[{"stepType":"stream","parameter":{},"name":"Reader","category":"reader"},{"stepType":"mysql",//插件名。"parameter":{"postSql":[],//导入后的准备语句。"datasource":"",//数据源。"column":[//列名。"id","value"],"writeMode":"insert",//写入模式，您可以设置为insert、replace或update。"batchSize":1024,//一次性批量提交的记录数大小。"table":"",//表名。"preSql":["delete from XXX;" //导入前的准备语句。]},"name":"Writer","category":"writer"}],"setting":{"errorLimit":{//错误记录数。"record":"0"},"speed":{"throttle":true,//当throttle值为flase时，mbps参数不生效，表示不限流；当throttle值为true时,表示限流。"concurrent":1, //作业并发数。"mbps":"12"//限流}},"order":{"hops":[{"from":"Reader","to":"Writer"}]}} https://help.aliyun.com/document_detail/137763.html，此回答整理自钉群“DataWorks交流群(答疑@机器人)”
