Description

@advancedxy

What is the problem the feature request solves?

When implementing BloomFilterMightContain, I noticed the second parameter is usually came from a hash function, such as xxhash64. Comet only support murmur3_hash in the Rust side. We should also support other hash function in Comet.

Describe the potential solution

Add various hash expression support, such as:


  • Md5
  • Sha1
  • Sha2
  • Crc32

This functions may has lower priority
