[GitHub] [pinot] mneedham opened a new issue, #10549: Choose which fields get flattened by complexType

[via GitHub]

mneedham opened a new issue, #10549:
URL: https://github.com/apache/pinot/issues/10549

   Say we have the following event structure:
   
   ```json
   {
        "...",
        "auditFields": {
                "a": "b",
                "c": "d"
        },
        "results": [
                {
                        "name": "result1",
                        "value": 33.2
                },
                {
                        "name": "result2",
                        "value": 45.6
                }
        ]
   }
   ```
   
   We want to create the following columns:
   
   ```
   results.name
   results.value
   auditFields
   ```
   
   At the moment I don't think that's possible as auditFields will be flattened 
into:
   
   
   ```
   audiFields.a
   auditFields.c
   ```
   
   By this line of code - 
https://github.com/apache/pinot/blob/master/pinot-segment-local/src/main/java/org/apache/pinot/segment/local/recordtransformer/ComplexTypeTransformer.java#L176
   
   Can we make the columns that get flattened configurable, like the fields to 
unnest can be configured?
