> Please see IGNITE-17318 for partial description of what needs to be achieved.
> I expect that hash index records will have the following structure:
> {code:java}
> [ indexId | partitionId | hash | tuple | rowId ] -> []{code}
> Fixed-length prefix should cover indexId, partitionId and hash value.
> Searching rows effectively becomes a scan, but this is fine.
> Hashing must be performed internally, hash function already presents somewhere in the code.
> Is far as I understand, PK is going to be implemented as a secondary hash index.
