Changelog JSON Format

WARNING: The CDC format changelog-json is deprecated since Flink CDC version 2.2. The CDC format changelog-json was introduced at the point that Flink didn’t offer any CDC format. Currently, Flink offers several well-maintained CDC formats i.e.Debezium CDC, MAXWELL CDC, CANAL CDC, we recommend user to use above CDC formats.

Compatibility Note

User can still obtain and use the deprecated changelog-json format from older Flink CDC version e.g. flink-format-changelog-json-2.1.1.jar.
