enable_display_name_attribute |
bool
Enable displayName attribute in Avro schema. The Avro specification requires field names to be alphanumeric. By default, in cases when column names do not conform to these requirements (e.g. non-ascii unicode codepoints) and Avro is requested as an output format, the CreateReadSession call will fail. Setting this field to true, populates avro field names with a placeholder value and populates a "displayName" attribute for every avro field with the original column name. |
