Pavel Tupitsyn updated IGNITE-17994:
------------------------------------
Description:
HashCalculator converts BigDecimal and BigInteger to double to compute hash.
Under the hood this involves weird and complicated logic - bit magic for
BigInteger, string conversion for BigDecimal.
This logic is too hard to replicate in non-Java clients.
I propose to use toByteArray() instead to compute the hash. Byte
representation of those types is used in BinaryTuple already, so clients know
how to work with that.
> Use toByteArray for colocation hash of BigDecimal and BigInteger
