DataWorks中MySQL Reader脚本开发介绍是什么？

使用脚本开发的详情请参见通过脚本模式配置任务。本文为您提供单库单表和分库分表的配置示例：配置单库单表 {"type":"job","version":"2.0",//版本号。"steps":[{"stepType":"mysql",//插件名。"parameter":{"column":[//列名。"id"],"connection":[{ "querySql":["select a,b from join1 c join join2 d on c.id = d.id;"], //使用字符串的形式，将querySql写在connection中。"datasource":"",//数据源。"table":[//表名，即使只有一张表，也必须以[]的数组形式书写。"xxx"]}],"where":"",//过滤条件。"splitPk":"",//切分键。"encoding":"UTF-8"//编码格式。},"name":"Reader","category":"reader"},{"stepType":"stream","parameter":{},"name":"Writer","category":"writer"}],"setting":{"errorLimit":{"record":"0"//错误记录数。},"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"}]}}配置分库分表说明 分库分表是指在MySQL Reader端可以选择多个MySQL数据表，且表结构保持一致。{"type": "job","version": "1.0","configuration": {"reader": {"plugin": "mysql","parameter": {"connection": [{"table": ["tbl1","tbl2","tbl3"],"datasource": "datasourceName1"},{"table": ["tbl4","tbl5","tbl6"]," https://help.aliyun.com/document_detail/137725.html，此回答整理自钉群“DataWorks交流群(答疑@机器人)”
