> Querying against large scale database is a good way to test Impala. However,
> it is impractical to do in single node development machine.
> Frontend testing does not actually run the test query in backend executor and
> can benefit from simulated large scale test cases. This can be done by either
> instrumenting the CatalogD metadata loading code or the COMPUTE STATS query
> to multiply numRows, numNull, numTrues, and numFalses to a scale constant. We
> can start by hacking TpcdsCpuCostPlannerTest to simulate 1TB TPC-DS query
> planning.
