Hey,
I just wanted to ask the reason for using murmur hash here instead of some other cryptographically strong hash like SHA3 or BLAKE3 or something? Wouldn't using murmur hash affect accuracy of results? I understand that you are optimising for memory instead of CPU so I feel using a cryptographically secure hash will still stay aligned with your goals.
Please advise if my thoughts are correct here. Thanks
