> In the last release, we introduced a new module {{flink-formats}}. Currently only {{flink-avro}} is located there but we will add more formats such as {{flink-json}}, {{flink-protobuf}}, and so on. For better separation of concerns we want decouple connectors from formats: e.g., remove {{KafkaAvroTableSource}} and {{KafkaJsonTableSource}}.
> A newly introduced {{FormatFactory}} will use Java service loaders to discovery available formats in the classpath (similar to how file systems are discovered now). A {{Format}} will provide a method for converting {{byte[]}} to target record type.
