Insert Default Values for Missing JSON Elements in Named Tuple Parsing

Why it matters

This feature solves the problem of JSON input data missing certain elements in named tuples during parsing. It prevents errors and simplifies data ingestion by automatically filling missing tuple elements with their default values, improving robustness and user experience.

How to use it

Enable this feature by setting the setting input_format_json_defaults_for_missing_elements_in_named_tuple to 1 or true. When enabled, missing named tuple elements in JSON input will default to their predefined values instead of causing parsing errors.
