[jira] [Created] (FLINK-24391) flink-json formats should support an option to extract the raw message into a column

Shengnan YU created FLINK-24391:
-----------------------------------

             Summary: flink-json formats should support an option to extract the raw message into a column
                 Key: FLINK-24391
                 URL: https://issues.apache.org/jira/browse/FLINK-24391
             Project: Flink
          Issue Type: Improvement
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
    Affects Versions: 1.13.2
            Reporter: Shengnan YU


Sometimes we only need to extra some columns of the json message for indexing but the whole raw message as another column for stroage. Especially in the case that source data's schema is not exactly the same.
