datax是阿里巴巴开源的一款数据同步工具,可以用于不同数据源之间的数据同步操作。下面我们将以mysql作为数据源,介绍如何使用datax实现mysql的数据同步。
{"job": {"content": [{"reader": {"name": "mysqlreader","parameter": {"username": "root","password": "123456","column": ["id","name","age"],"splitPK": "","connection": [{"table": ["user"],"jdbcUrl": ["jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8"]}]}},"writer": {"name": "mysqlwriter","parameter": {"username": "root","password": "123456","column": ["id","name","age"],"preSql": [],"postSql": [],"connection": [{"jdbcUrl": "jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8","table": ["user_copy"]}]}}}],"setting": {"speed": {"channel": "3","byte": "1048576"}}}}
以上是datax同步mysql的配置文件,其中读取源是mysql,写入目标也是mysql。需要注意的是,读取和写入的用户名、密码、表名、连接url等项需要与目标数据库的配置一致。配置完毕后,可以通过如下命令启动同步任务:
python datax.py ./mysql_job.json
以上是关于使用datax同步mysql的详细介绍,希望能对读者有所帮助。
