Values (default in bold)

false, true


A session configuration that modifies the JSON serialization behavior of ORC, JSON, Ion, and Parquet formatted data. When both json_serialization_parse_nested_strings and json_serialization_enable are true, string values that are stored in complex types (such as, maps, structures, or arrays) are parsed and written inline directly into the result if they are valid JSON. If json_serialization_parse_nested_strings is false, strings within nested complex types are serialized as escaped JSON strings. For more information, see Serializing complex types containing JSON strings.
