  4. def analyzeInPython(func: PythonFunction, exprs: Seq[Expression], tableArgs: Seq[Boolean]): PythonUDTFAnalyzeResult

    Runs the Python UDTF's analyze static method.

    Runs the Python UDTF's analyze static method.

    When the Python UDTF is defined without a static return type, the analyzer will call this while resolving table-valued functions.

    This expects the Python UDTF to have analyze static method that take arguments:

    - The number and order of arguments are the same as the UDTF inputs - Each argument is an AnalyzeArgument, containing:

    • data_type: DataType
    • value: Any: if the argument is foldable; otherwise None
    • is_table: bool: True if the argument is TABLE

    and that return an AnalyzeResult.

    It serializes/deserializes the data types via JSON, and the values for the case the argument is foldable are pickled.

    AnalysisException with the error class "TABLE_VALUED_FUNCTION_FAILED_TO_ANALYZE_IN_PYTHON" will be thrown when an exception is raised in Python.
