Summary: Investigate XXH3
Key: IMPALA-14729
URL: https://issues.apache.org/jira/browse/IMPALA-14729
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Reporter: Zoltán Borók-Nagy
At the time of writing, XXH3 is considered to be the "best hash algorithm" in
terms of speed, quality, and it works well on different input sizes.
It has 64-bit and 128-bit variants.
We should asses the Impala code, and see if we should replace
* Murmur
* FNV
* FastHash
* ? CRC
Related tickets are
* IMPALA-2281
* IMPALA-3255
Those all pre-date XXH3 which was initially released in 2019/2020.
