/*
* Stored procedure for ExportBenchmark
*
* 2 tables -- all datatypes with nullable and not nullable variants
*
* Call the SP with DB tables insert count and export tables insert count.
* This allows mixing DB insert to export insert ratio, following the recent
* Flipkart customer case where export rows could exceed DB inserts as much as 10:1.
*
* Since DB inserts and export inserts are parameterized, it's possible to try many
* variations in the test driver.
