1.3.0 (2023-03-28)
New Features
Added support for delimiters parameter in functions.initcap().
Added support for functions.hash() to accept a variable number of input expressions.
Added API Session.conf for getting, setting or checking the mutability of any runtime configuration.
Added support for managing case sensitivity in Row results from DataFrame.collect using case_sensitive parameter.
Added indexer support for snowflake.snowpark.types.StructType.
Added a keyword argument log_on_exception to Dataframe.collect and Dataframe.collect_no_wait to optionally disable error logging for SQL exceptions.
Bug Fixes
Fixed a bug where a DataFrame set operation(DataFrame.substract, DataFrame.union, etc.) being called after another DataFrame set operation and DataFrame.select or DataFrame.with_column throws an exception.
Fixed a bug where chained sort statements are overwritten by the SQL simplifier.
Improvements
Simplified JOIN queries to use constant subquery aliases (SNOWPARK_LEFT, SNOWPARK_RIGHT) by default. Users can disable this at runtime with session.conf.set('use_constant_subquery_alias', False) to use randomly generated alias names instead.
Allowed specifying statement parameters in session.call().
Enabled the uploading of large pandas DataFrames in stored procedures by defaulting to a chunk size of 100,000 rows.
