Examples of ThreadInsert

org.apache.derbyTesting.system.oe.load.ThreadInsert

Multi-threaded version of SimpleInsert. A number of threads execute the INSERT statements (each with their own connection). All the rows for a given warehouse are executed by one thread. The threads each get a warehouse to complete and then insert all the rows. Then they loop back to get the next warehouse. Warehouses are assigned to threads in a first come first served fashion. The main thread also inserts the ITEM table.
By default the number of threads is the number of cpus on the machine, unless the scale to be loaded is larger than the number of threads. Then the number of threads will be equal to the scale. If the scale is one or the number of threads is one then the load is just like SimpleInsert.
The number of threads can be set but if it it larger than the scale then the number of threads will be equal to the scale.
It is assumed that foreign key constraints are created after the load.
