-------------------------------
Summary: [Rust] Default to non-cryptographic hash function?
Key: ARROW-10554
URL: https://issues.apache.org/jira/browse/ARROW-10554
Project: Apache Arrow
Issue Type: Wish
Reporter: Ritchie
THis isn't a major issue/ or even one at all.
I was wondering how guys are looking towards using a non-cryptographic hash
function (as SeaHash or Fnv) as default for Schema (and maybe other locations
in crate).
Arrow currently defaults to the default HashMap and HashSet. This uses a
cryptographic hasher to guard you against DOS-attacks, which I believe isn't
needed most of the time. This extra security has some performance overhead.
