> Currently our {{DeserializationSchema}} has supported to emit multi messages
> for one input record. There is some cases that the json data is not a json
> object in top level, for example:
> {code:SQL}
> CREATE TABLE source (
> col1 int,
> col2 varchar
> ) WITH (
> ...
> 'format' = 'json'
> )
> {code}
> With following data.
> {code:json}
> [
> {"col1": 1, "col2": "hello"},
> {"col1": 2, "col2": "flink"}
> ]
> {code}
