> In my case,one kafka topic store multiple table data,for example:
>  \{"id":"121","source":"users","content":{"name":"test01","age":20,"addr":"addr1"}}
>  \{"id":"122","source":"users","content":{"name":"test02","age":23,"addr":"addr2"}}
>  \{"id":"124","source":"users","content":{"name":"test03","age":34,"addr":"addr3"}}
>  \{"id":"124","source":"order","content":{"orderId":"100001","price":34,"addr":"addr1231"}}
>  \{"id":"125","source":"order","content":{"orderId":"100002","price":34,"addr":"addr1232"}}
>  \{"id":"126","source":"order","content":{"orderId":"100003","price":34,"addr":"addr1233"}}
>   
>  I  just want to consume data from  talbe order,flink sql ddl like this:
>  CREATE TABLE order (
>  orderId STRING,
>  age INT,
>  addr STRING
>  )
>  with (
>  'connector'='kafka',
>  'topic'='kafkatopic',
>  'properties.bootstrap.servers'='localhost:9092',
>  'properties.group.id'='testGroup',
>  'scan.startup.mode'='earliest-offset',
>  'format'='json',
>  'path-fliter'='$[?(@.source=="order")]',
>  'path-data'='$.content'
>  );
>   
>  path-fliter and path-data can use  JsonPath ([https://github.com/json-path/JsonPath])
