When a session uses a file source, you can configure it to read the source with one thread or with multiple threads. The Integration Service creates one connection to the file source when you configure the session to read with one thread, and it creates multiple concurrent connections to the file source when you configure the session to read with multiple threads.
Use the following types of partitioned file sources:
You can configure a session to read flat file, XML, or COBOL source files.
You can configure a session to use an operating system command to generate source data rows or generate a file list.
When connecting to file sources, you must choose the same connection type for all partitions. You may choose different connection objects as long as each object is of the same type.
To specify single- or multi-threaded reading for flat file sources, configure the source file name property for partitions 2-
. To configure for single-threaded reading, pass empty data through partitions 2-
. To configure for multi-threaded reading, leave the source file name blank for partitions 2-
