RETURNS BYTES
OPTIONS (
  description = '''Computes a sketch that represents the scalar intersection of sketchA and sketchB.
Note that cardinality estimation accuracy, plots, and error tables are the same as the Theta Sketch.
This function only applies to Tuple Sketches with an INT64 summary column.

Param sketchA: the first sketch "A" as BYTES.
Param sketchB: the second sketch "B" as BYTES.
Defaults: seed = 9001.
Returns: a Compact Tuple Sketch as BYTES.
