             Summary: support hash_fn for Python ApproximateUniqueCombineFn transform
                 Key: BEAM-7525
                 URL: https://issues.apache.org/jira/browse/BEAM-7525

          Issue Type: Task
          Components: sdk-py-core
            Reporter: Hannah Jiang


ApproximateUniqueCombineFn is using default hash function for estimation.

We can pass a hash_fn and overwrite default hash function to support better estimation performance.
