Hi Will, The community is currently working on improving the Kafka Avro integration for Flink SQL. There's a PR [1]. If you like, you could try it out and give some feedback.
Timo (in CC) has been working Kafka Avro and should be able to help with any specific questions. Best, Fabian [1] https://github.com/apache/flink/pull/6218 2018-07-03 3:02 GMT+02:00 Will Du <will...@gmail.com>: > Hi folks, > I am working on using avro table source mapping to kafka source.
