Ritchie updated ARROW-10554:
----------------------------
Description:
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 (aHash seems to be very fast) as default for Schema (and maybe other
locations in crate).
Arrow currently defaults to the default HashMap and HashSet. This uses a
cryptographic hasher, which I believe isn't needed most of the time. This extra
security has quite some performance overhead.

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.
