Work Description: Hannah-Jiang commented on pull request #8799:
[WIP][BEAM-6693] replace mmh3 with default hash function
URL: https://github.com/apache/beam/pull/8799
Replace mmh3 with default python hash function, because it's not reasonable
to bring this inconvenience to production with only a little bit improvement
with estimation for a loose estimation algorithm.
