Workgen can manage a dynamic set of tables by creating/deleting tables to stay within a specific database size:

• As long as the database size has not reached the specified higher limit, Workgen creates tables.
• When the database is greater than the higher limit in size, Workgen starts dropping tables until the lower limit has been reached.

This ticket should address the first scenario as it may cause the database to have "too many files": if the workload does not select any of the newly created files or does very slow operations, Workgen will keep creating files.
