FAQ

1、mysql只支持mysql5.7以上

2、com.streamsets.pipeline.api.base.OnRecordErrorException: TEXT_GENERATOR_01 - Record 'mysql-bin.000001:3800' is missing field /text
    at com.streamsets.pipeline.stage.destination.kafka.KafkaTarget.writeOneMessagePerRecord(KafkaTarget.java:255)

这个错误就是kafka设置为Text导致，因为从mysql抽取的数据为json格式。如：

{"BinLogFilename":"mysql-bin.000001","Type":"UPDATE","Table":"weblog","ServerId":2,"BinLogPosition":6408,"Database":"test","OldData":{"args":"123","id":10,"method":"12df34","create_time":1625251291000,"url":"name1qw0","ip":"123"},"Data":{"args":"123","id":10,"method":"12df34","create_time":1625251291000,"url":"name3423qw0","ip":"123"},"Timestamp":1626261330000,"Offset":"mysql-bin.000001:6408"}

3、mysql驱动一定要正确，这个看日志，如果显示
