/**
* Test large cached tables by setting up a cached table of 100000 records
* or more and a much smaller memory table with about 1/100th rows used.
* Populate both tables so that an indexed column of the cached table has a
* foreign key reference to the main table.
*
* This database can be used to demonstrate efficient queries to retrieve
* the data from the cached table.
*
* 1.7.1 insert timings for 100000 rows, cache scale 12:
* simple table, no extra index: 52 s
* with index on lastname only: 56 s
* with index on zip only: 211 s
* foreign key, referential_integrity true: 216 s
*
* The above have improved a lot in 1.7.2
*
* This test now incorporates the defunct TestTextTables
