表格存储datax迁移数据支持含有自增主键的表吗？

基本材料：同一台机器，安装了MySQL8，两个库：nacos 和 datax-demo，在nacos库新建一个视图v_datax_role_user；在datax-demo新建一个表t_datax_role_user；【注：使用的都是root用户】job.json内容为：{ "job": {  "setting": {   "speed": {    "channel": 3   },   "errorLimit": {    "record": 0,    "percentage": 0.02   }  },  "content": [   {    "reader": {     "name": "mysqlreader",     "parameter": {      "username": "nacos",      "password": "nacos",      "connection": [       {        "querySql": [         "SELECT username, password, enabled, role FROM v_datax_role_user;"        ],        "jdbcUrl": [         "jdbc:mysql://127.0.0.1:3306/nacos?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true"        ]       }      ]     }    },    "writer": {     "name": "mysqlwriter",     "parameter": {      "writeMode": "insert",      "username": "root",      "password": "root",      "column": [       "username",       "password",       "enabled",       "role"      ],      "preSql": [       "delete from t_datax_role_user"      ],      "connection": [       {        "jdbcUrl": "jdbc:mysql://127.0.0.1:3306/datax-demo?useUnicode=true&characterEncoding=utf8&serverTimezoneGMT%2B8&useSSL=true&rewriteBatchedStatements=true",        "table": [         "t_datax_role_user"        ]       }      ]     }    }   }  ] }}打算将nacos 的users和role同步到 datax-demo库的t_datax_role_user，报异常了。具体错误信息为：经DataX智能分析,该任务最可能的错误原因是:com.alibaba.datax.common.exception.DataXException: Code:[MYSQLErrCode-02], Description:[数据库服务的IP地址或者Port错误，请检查填写的IP地址和Port或者联系DBA确认IP地址和Port是否正确。如果是同步中心用户请联系DBA确认idb上录入的IP和PORT信息和数据库的当前实际信息是一致的].  -  具体错误信息为：com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

请问，我用dataworks集成资源归集150w左右的数据，5分钟完事，用开源的datax归集，现在得一个多小时，之前用开源的datax归集才5分钟就完事了，请问有人对写入odps的引擎做了限制吗？

问一下，我在shell脚本配置datax相关信息，datax下有个启动文件datax.py 这个文件路径是这个嘛？

datax拉取maxcompute数据，获取不到最新几天分区，这个是有分区数量限制的吗

您好，有个Dataphin从MySQL到ODPS同步报错的问题需要看下 Uid：1192266191409506 问题描述：客户ODPS以及MySQL数据源测试网络都正常，但是在进行同步中却报DataX无法连接对应的数据库，可能原因是：1) 配置的ip/port/database/jdbc错误，无法连接。2) 配置的username/password错误，鉴权失败。请和DBA确认该数据库的连接信息是否正确。

datawork datax 使用公共资源链接 ecs自建的数据但是不同是为啥？ ecs安全组也加了dataworks公共资源的网络白名单了

DataWorks正在执行的datax任务需要怎么kill掉？

请问odps有没有对开源的datax写入进行限流啊？
