Harvey Yue commented on FLINK-20952:
------------------------------------
Hi, I'm working this feature, currently, I add all json attributes including
debezium, maxwell and canal, also the builder class in JsonOptions. Instead of
implementing which DebeziumJsonOptions, CanalJsonOptions and MaxwellJsonOptions
inherit JsonOptions, when add a new attribute to JsonOptions, we have no need
to touch the builder class in these subclass.
If this solution is ok, I will post a pr.
> Changelog json formats should support inherit options from JSON format

> Recently, we introduced several config options for json format, e.g.
> FLINK-20861. It reveals a potential problem that adding a small config option
> into json may need touch debezium-json, canal-json, maxwell-json formats.
> This is verbose and error-prone. We need an abstract machanism support
> reuable options.
