jbapple commented on pull request #143: PARQUET-1609: Specify which xxhash
carefully
URL: https://github.com/apache/parquet-format/pull/143
The hash function "xxhash" is actually a number of different hash
functions including xxHash, XXH64, XXH32, and XXH3. Additionally,
these hash functions accept "seeds", as most modern hash functions do,
including MurmurHash variants.
This patch specifies that the BloomFilter hash function default is
XXH64 with a seed of 0. It omits the confusing note about the ISA and
different variants of xxHash, since XXH64 is apparently
architecture-independent.
Make sure you have checked _all_ steps below.
