v0.9.0

0.9.0 (2022-08-30)

New Features:

• Added support for displaying source code as comments in the generated scripts when registering UDFs.
  This feature is turned on by default. To turn it off, pass the new keyword argument source_code_display as False when calling register() or @udf().
• Added support for calling table functions from DataFrame.select(), DataFrame.with_column() and DataFrame.with_columns() which now take parameters of type table_function.TableFunctionCall for columns.
• Added keyword argument overwrite to session.write_pandas() to allow overwriting contents of a Snowflake table with that of a Pandas DataFrame.
• Added keyword argument column_order to df.write.save_as_table() to specify the matching rules when inserting data into table in append mode.
• Added method FileOperation.put_stream() to upload local files to a stage via file stream.
• Added methods TableFunctionCall.alias() and TableFunctionCall.as_() to allow aliasing the names of columns that come from the output of table function joins.
• Added function get_active_session() in module snowflake.snowpark.context to get the current active Snowpark session.

Bug Fixes:

• Fixed a bug in which batch insert should not raise an error when statement_params is not passed to the function.
• Fixed a bug in which column names should be quoted when session.create_dataframe() is called with dicts and a given schema.
• Fixed a bug in which creation of table should be skipped if the table already exists and is in append mode when calling df.write.save_as_table().
• Fixed a bug in which third-party packages with underscores cannot be added when registering UDFs.

Improvements:

• Improved function function.uniform() to infer the types of inputs max_ and min_ and cast the limits to IntegerType or FloatType correspondingly.
