/**
 * 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
 *
 * @version 1.7.2
 * @since 1.7.0
