felpasl opened a new issue, #14607:
URL: https://github.com/apache/pinot/issues/14607

   First, I want to express my gratitude for your hard work on the Apache Pinot 
project. It has been an invaluable tool for our data analytics needs, and we 
greatly appreciate the continuous improvements and updates.
   
   However, I have encountered some challenges while trying to ingest JSON data 
that contains arrays. Specifically, I received a `MismatchedInputException when 
attempting to deserialize a value of type 
java.util.HashMap<java.lang.String,java.lang.Object> from an array value (token 
JsonToken.START_ARRAY)`. This issue has made it difficult to work with JSON 
data containing nested arrays effectively.
   
   My kafka message has this payload:
   ``` json
   [{
       "start_time": 1733420042603,
       "route_id": "5d9ece83"
   },
   {
       "start_time": 1733420042603,
       "route_id": "5d9ece83"
   }]
   ```
   
   Feature Request: I would like to request the following features or 
enhancements:
   
   Enhanced Documentation Sample:
   
   - Detailed examples and guidelines for handling JSON data with root arrays 
during ingestion.
   
   Feature Enhancement:
   
   - If not possible Improved support for JSON data containing root arrays.
   
   Best regards.
