Release

1.33.0 (2025-06-19)

Snowpark Python API Updates

New Features

• Added support for MySQL in DataFrameWriter.dbapi (PrPr) for both Parquet and UDTF-based ingestion.
• Added support for PostgreSQL in DataFrameReader.dbapi (PrPr) for both Parquet and UDTF-based ingestion.
• Added support for Databricks in DataFrameWriter.dbapi (PrPr) for UDTF-based ingestion.
• Added support to DataFrameReader to enable use of PATTERN when reading files with INFER_SCHEMA enabled.
• Added support for the following AI-powered functions in functions.py:
  • ai_complete
  • ai_similarity
  • ai_summarize_agg (originally summarize_agg)
  • different config options for ai_classify
• Added support for more options when reading XML files with a row tag using rowTag option:
  • Added support for removing namespace prefixes from col names using ignoreNamespace option.
  • Added support for specifying the prefix for the attribute column in the result table using attributePrefix option.
  • Added support for excluding attributes from the XML element using excludeAttributes option.
  • Added support for specifying the column name for the value when there are attributes in an element that has no child elements using valueTag option.
  • Added support for specifying the value to treat as a null value using nullValue option.
  • Added support for specifying the character encoding of the XML file using charset option.
  • Added support for ignoring surrounding whitespace in the XML element using ignoreSurroundingWhitespace option.
• Added support for parameter return_dataframe in Session.call, which can be used to set the return type of the functions to a DataFrame object.
• Added a new argument to Dataframe.describe called strings_include_math_stats that triggers stddev and mean to be calculated for String columns.
• Added support for retrieving Edge.properties when retrieving lineage from DGQL in DataFrame.lineage.trace.
• Added a parameter table_exists to DataFrameWriter.save_as_table that allows specifying if a table already exists. This allows skipping a table lookup that can be expensive.

Bug Fixes

• Fixed a bug in DataFrameReader.dbapi (PrPr) where the create_connection defined as local function was incompatible with multiprocessing.
• Fixed a bug in DataFrameReader.dbapi (PrPr) where databricks TIMESTAMP type was converted to Snowflake TIMESTAMP_NTZ type which should be TIMESTAMP_LTZ type.
• Fixed a bug in DataFrameReader.json where repeated reads with the same reader object would create incorrectly quoted columns.
• Fixed a bug in DataFrame.to_pandas() that would drop column names when converting a dataframe that did not originate from a select statement.
• Fixed a bug that DataFrame.create_or_replace_dynamic_table raises error when the dataframe contains a UDTF and SELECT * in UDTF not being parsed correctly.
• Fixed a bug where casted columns could not be used in the values-clause of in functions.

Improvements

• Improved the error message for Session.write_pandas() and Session.create_dataframe() when the input pandas DataFrame does not have a column.
• Improved DataFrame.select when the arguments contain a table function with output columns that collide with columns of current dataframe. With the improvement, if user provides non-colliding columns in df.select("col1", "col2", table_func(...)) as string arguments, then the query generated by snowpark client will not raise ambiguous column error.
• Improved DataFrameReader.dbapi (PrPr) to use in-memory Parquet-based ingestion for better performance and security.
• Improved DataFrameReader.dbapi (PrPr) to use MATCH_BY_COLUMN_NAME=CASE_SENSITIVE in copy into table operation.

  • ai_complete
  • ai_similarity
  • ai_summarize_agg (originally summarize_agg)
  • different config options for ai_classify
• Added a ttl cache to describe queries. Repeated queries in a 15 second interval will use the cached value rather than requery Snowflake.

Bug Fixes

• Fixed a bug in DataFrameReader.dbapi (PrPr) where the create_connection defined as local function was incompatible with multiprocessing.
• Fixed a bug in DataFrameReader.dbapi (PrPr) where databricks TIMESTAMP type was converted to Snowflake TIMESTAMP_NTZ type which should be TIMESTAMP_LTZ type.

• Added a new argument to Dataframe.describe called strings_include_math_stats that triggers stddev and mean to be calculated for String columns.
• Added debuggability improvements to show a trace of most recent dataframe transformations if an operation leads to a SnowparkSQLException. Enable it using snowflake.snowpark.context.configure_development_features(). This feature also depends on AST collection to be enabled in the session which can be done using session.ast_enabled = True.
• Improved the error message for Session.write_pandas() and Session.create_dataframe() when the input pandas DataFrame does not have a column.
• Added support for retrieving Edge.properties when retrieving lineage from DGQL in DataFrame.lineage.trace.
