json_serialization_parse_nested_strings
Values (default in bold)
false, true
Description
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.
