    Description

      Quoting from Slack thread -

      Hudi connector is not great at reading values from the deeply nested objects. Historically we've got a table where one field has around 5000 nested fields, so the user that only tries to read a few fields quickly runs out of RAM because apparently the whole object is being read into memory.

      Hudi connector needs to implement `HiveMetadata#applyProjection` to support projection for nested fields.
