There is one reader thread and multiple writer threads. Each writer thread is writing a bunch of rows, then it does COMMIT the transaction. The writer threads are writing between 500 and 100.000 records, depending on the number of columns which are transferred ( 500 for more then 50 columns, 100.000 for 1- 2 columns ).
