Github user beyond1920 commented on the issue: https://github.com/apache/flink/pull/3406 @fhueske , thanks for your review. I updated the pr based on your comments. Your suggestion about moving the annotation from TableSource to TableSourceConverter is good, I changed the pr in this way. About not use scanning at all but exactly specify the Converter classes. It can work, too. However, if somebody adds new tableSourceConverters , such as parquetTableSourceConverter or else, users need to change the code or config file to register new added Converters, right? However scanning method can finds all converters automatically. Let me know what's your opinion, thanks.
