(MemSQL CTO here) You're right, MemSQL doesn't support foreign keys as of yet, but none of these benchmarks require foreign key support. Two of them (TPC-H and TPC-DS) are a set of complex SELECT queries where foreign keys are not relevant at all. TPC-C is a write heavy benchmark, but the specification doesn't require foreign keys to be maintained (the data model does indicate the foreign key relationships though)[1]. These are unofficial benchmark results (not independently verified by TPC), so our interpretation of the specs may not be 100% correct, but I think we got it right as far as foreign keys are concerned.
