关于FlinkSQL的相关问题:1、请问使用Flink1.90版本的sql实现从Kafka读取数据,统计,输出数据到Kafka,数据格式是以csv形式的,kafka的format那块请问怎么写?
报错如下:
Caused by: org.apache.flink.table.api.ValidationException: Could not map the schema field 'fruit' to a field from source. Please specify the source field from which it can be derived.
请问format那块该怎么写才对? 谢谢!
