Antoine Pitrou commented on ARROW-3298:
---------------------------------------
What complicates things a bit is that there are several different versions of
Murmur (murmur2, murmur3, 32-bit-hash-producing, 64-bit-hash-producing) and
also potentially several different implementations of each (with different
performance characteristics).
So some review of current usage accross the codebase (Arrow, Plasma, Parquet,
Gandiva) is needed. [~fsaintjacques]
> [C++] Move murmur3 hash implementation to arrow/util
