20  * The hash code generation is based on the public domain MurmurHash3 from Austin Appleby:
21  * https://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
22  *
23  * We use only the 32 bit variant because the 2 produce different result while
24  * we need to produce the same result regardless of the architecture as
25  * clients can be both 64 or 32 bit at the same time.
