on GitHub

0.11.0 (2022-09-28)

Behavior Changes:

• Session.add_packages() now raises ValueError when the version of a package cannot be found in Snowflake Anaconda channel. Previously, Session.add_packages() succeeded, and a SnowparkSQLException exception was raised later in the UDF/SP registration step.

New Features:

• Added method FileOperation.get_stream() to support downloading stage files as stream.
• Added support in functions.ntiles() to accept int argument.
• Added the following aliases:
  • functions.call_function() for functions.call_builtin().
  • functions.function() for functions.builtin().
  • DataFrame.order_by() for DataFrame.sort()
  • DataFrame.orderBy() for DataFrame.sort()
• Improved DataFrame.cache_result() to return a more accurate Table class instead of a DataFrame class.
• Added support to allow session as the first argument when calling StoredProcedure.

Improvements:

• Improved nested query generation by flattening queries when applicable.
  • This improvement could be enabled by setting Session.sql_simplifier_enabled = True.
  • DataFrame.select(), DataFrame.with_column(), DataFrame.drop() and other select-related APIs have more flattened SQLs.
  • DataFrame.union(), DataFrame.union_all(), DataFrame.except_(), DataFrame.intersect(), DataFrame.union_by_name() have flattened SQLs generated when multiple set operators are chained.
• Improved type annotations for async job APIs.

Bug Fixes:

• Fixed a bug in which Table.update(), Table.delete(), Table.merge() try to reference a temp table that does not exist.
