In an interview with Volvo, they asked about nested json files. Thanks for including this topic and a very defined explanation.

When we try to read multi line json we have to provide .option("multiLine","true"), otherwise it fails with AnalysisException. Why is this not needed for nested json. it works with out this "multiline" option. Can you please tell why?

Hi Manish, Thank you for the videos , its really helpful, One small question, for csv file reading corrupt data we had to create our schema with _corrupt_record column, however for json , how come it is not needed

One of the reasons: JSON is a semi-structured data format, meaning it allows for nested data structures and varied schemas. When reading JSON files, Spark uses a schema inference mechanism that can accommodate this flexibility. If it encounters a record that doesn't conform to the expected structure, it can easily isolate the entire record as a corrupt entry and store it in the _corrupt_record column. CSV files are structured data formats that expect a uniform schema across all rows. If a CSV record deviates from this structure (e.g., missing fields, extra fields, or improperly formatted data), Spark cannot automatically infer how to handle the corruption without an explicit schema definition. This is why you need to define your schema, including a _corrupt_record column if you want to catch those corrupt records.
