Tools to generate large synthetic data sets for testing?
I need to generate large (1TB-3TB) synthetic MySQL datasets for testing, with a number of requirements:

a) custom output formatting (SQL, CSV, fixed-len row, etc)
b) referential integrity support (ie, child tables should reference PK values, no orphans,etc)
c) able to generate multiple tables in parallel
d) preferably able to operate without a GUI and/or manual intervention
e) uses a well defined templating construct for data generation
f) preferably open source

Does anyone out there know of a product that meets at least most of these requirements?

I found a PHP based data generation script ( that is extensible in its output formatting, so it should do everything I need it to do.
