    The factories were never public API and have been introduced in the last 
release. The sources were publicly documented:

> 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.
