To configure a session to read a file with a single thread, pass empty data through partitions 2-

n.

To pass empty data, create a file with no data, such as “empty.txt,” and put it in the source file directory. Then, use “empty.txt” as the source file name.

The following table shows the source file name and values when the Integration Service creates one thread to read ProductsA.txt. It reads rows in the file sequentially. After it reads the file, it passes the data to three partitions in the transformation pipeline:

The following table shows the source file name and values when the Integration Service creates two threads. It creates one thread to read ProductsA.txt, and it creates one thread to read ProductsB.txt. It reads the files concurrently, and it reads rows in the files sequentially:

If you use FTP to access source files, you can choose a different connection for each direct file.
