yuanlihan opened a new issue #1681: Extract data from data source with nested structure
URL: https://github.com/apache/incubator-doris/issues/1681
 
 
   **Currently, Doris is not well-supported for nested data parsing in data ingestion**
   Users may need to load data sources, like JSON/Parquet files, with nested structure.
   
   Now we can extract data from JSON string by column mapping using function `get_json_string` with specified `jsonpath`.
   
   It is quite useful to have a general way to extract data from nested structure. For example, we can read all non-primitive fields from different data sources as JSON string(or some general structure) first, then extract data by `jsonpath` at the stage of column mapping.
