New in version 4.2.0.

Parameters

col1Column or column name: The first TupleSketch column
col2Column or column name: The second TupleSketch column
modeColumn or str, optional: The summary mode: “sum” (default), “min”, “max”, or “alwaysone”

Returns

Column: The binary representation of the intersected TupleSketch.

Examples

>>> from pyspark.sql import functions as sf
>>> df = spark.createDataFrame([(1, 10, 2, 20), (2, 20, 3, 30), (3, 30, 4, 40)], ["key1", "v1", "key2", "v2"])  # noqa
>>> df = df.agg(
