> Need to create infrastructure to calculate hash code for colocation key.
> Apache Ignite uses partitioning by a hash function. The hash function should
> have relatively even distribution. Because of it we can’t use primitive and
> very fast commutative hash functions (e.g. based on XOR). So the hash
> function should respect the order of fields that are included into the
> affinity key.
> It should be taken into account that the code for hash code calculation
> should be accessible from thin clients.
