> I think `schema` option is excess for ES Source, So, can we comment `schema` is deprecated in code and document? @EricJoy2048 Yes, in fact, I think **source** is sufficient...

> Thanks @CosmosNi for update, could you follow the suggestion of @EricJoy2048 to mark schema config in ES source as deprecated? Both in doc and code. @Hisoka-X mark schema config...

@Hisoka-X I have a problem，There are no array types in es，so when source include an array type,The engine will not be able to fight for the job.It is not up...

@Hisoka-X i add a label (array_column) to handle es array type,PTAL,thanks.
