Efficient processing of huge amount of data located on the disk is not our
current goal.
We target applications that process small amount of data that all can fit
into RAM.
We believe for such applications SQL/ODBC is not the best choice.

As far as limitations are conserned, there are two kinds of those:

1) The number of records has the same limitation as the number of elements
in std::vector;
2) The number of fields in a tuple is limited by the compiler's ability to
process recursive templates.

All our tests so far were done using very small amounts of data -- we did
not do any stress testing.
At this point we are just trying to propose the concept.
