Compatibility Issues

  • As new Schema object level is introduced, it is now discouraged to use schema for table schemas and warnings will be produced. Try using table_schema instead when you code with the new version.
  • Attributes like creation_time now uses local time instead of UTC time for consistency with other datetime attributes by default. Switch to old behavior by setting options.use_legacy_parsedate = True.
  • Attribute last_modified_time on tables and partitions now renamed into last_data_modified_time for clarity. Warnings might be produced with old attribute names.
