ebyhr opened a new pull request, #3574: URL: https://github.com/apache/iceberg-python/pull/3574
# Rationale for this change `apache-datasketches-theta-v1` was already listed as a valid blob type in PuffinBlobMetadata and BlobMetadata, but pyiceberg had no way to read the actual sketch data. This implements deserialization so callers can access NDV estimates stored in statistics Puffin files written by engines like Spark. ## Are these changes tested? Yes. ## Are there any user-facing changes? Yes. New `pyiceberg/table/theta_sketch.py` with ThetaSketch class and `theta_sketches_from_puffin_file` function. New optional dependency `datasketches` under the datasketches extra. -- This is an automated message from the Apache Git Service.
