Bump snowflake-snowpark-python from 1.26.0 to 1.30.0 in /python-wrapper

[dependabot]

Bumps snowflake-snowpark-python from 1.26.0 to 1.30.0.

Release notes

Sourced from snowflake-snowpark-python's releases.

Release

1.30.0 (2024-03-27)

Snowpark Python API Updates

New Features

• Added Support for relaxed consistency and ordering guarantees in Dataframe.to_snowpark_pandas by introducing the new parameter relaxed_ordering.
• DataFrameReader.dbapi (PrPr) now accepts a list of strings for the session_init_statement parameter, allowing multiple SQL statements to be executed during session initialization.

Improvements

• Improved query generation for Dataframe.stat.sample_by to generate a single flat query that scales well with large fractions dictionary compared to older method of creating a UNION ALL subquery for each key in fractions. To enable this feature, set session.conf.set("use_simplified_query_generation", True).
• Improved performance of DataFrameReader.dbapi by enable vectorized option when copy parquet file into table.
• Improved query generation for DataFrame.random_split in the following ways. They can be enabled by setting session.conf.set("use_simplified_query_generation", True):
  • Removed the need to cache_result in the internal implementation of the input dataframe resulting in a pure lazy dataframe operation.
  • The seed argument now behaves as expected with repeatable results across multiple calls and sessions.
• DataFrame.fillna and DataFrame.replace now both support fitting int and float into Decimal columns if include_decimal is set to True.
• Added documentation for the following UDF and stored procedure functions in files.py as a result of their General Availability.
  • SnowflakeFile.write
  • SnowflakeFile.writelines
  • SnowflakeFile.writeable
• Minor documentation changes for SnowflakeFile and SnowflakeFile.open()

Bug Fixes

• Fixed a bug for the following functions that raised errors .cast() is applied to their output
  • from_json
  • size

Snowpark Local Testing Updates

Bug Fixes

• Fixed a bug in aggregation that caused empty groups to still produce rows.
• Fixed a bug in Dataframe.except_ that would cause rows to be incorrectly dropped.
• Fixed a bug that caused to_timestamp to fail when casting filtered columns.

Snowpark pandas API Updates

New Features

• Added support for list values in Series.str.__getitem__ (Series.str[...]).
• Added support for pd.Grouper objects in group by operations. When freq is specified, the default values of the sort, closed, label, and convention arguments are supported; origin is supported when it is start or start_day.
• Added support for relaxed consistency and ordering guarantees in pd.read_snowflake for both named data sources (e.g., tables and views) and query data sources by introducing the new parameter relaxed_ordering.

Improvements

• Raise a warning whenever QUOTED_IDENTIFIERS_IGNORE_CASE is found to be set, ask user to unset it.
• Improved how a missing index_label in DataFrame.to_snowflake and Series.to_snowflake is handled when index=True. Instead of raising a ValueError, system-defined labels are used for the index columns.
