The indexes in the case where the value uniqueness might be determined by first
bytes become twice as fast (47811 vs 23518 ops/s).

> We need to implement an inlined *BinaryTuple* comparator in a sorted index
> for a B+tree.
> You need to take into account the format of the *BinaryTuple* and the fact
> that it can be truncated.
> As a basis, you can take
> *org.apache.ignite.internal.storage.index.BinaryTupleComparator*.
