Documentations

Compatibility issues

• PyODPS now returns struct values as namedtuples for tunnels to keep consistency with UDFs. For most of the cases your code might still work. If it doesn't, try configuring options.struct_as_dict = True.
• From v0.11.5 nullable property of columns is added for transactional tables, and default value for partition columns is False. If you use these column instances in some scenario, for instance, using them as common columns to create tables, non-nullable columns could be created and insertion of null values will result in errors. To ignore nullable flags in columns, try configuring sql.ignore_fields_not_null = True.
