Single Threader
The Single Threader step executes a sequence of steps in a single thread, which allows you to tune the performance of your transformations by limiting the number of threads or processors used:
To solve issues in transformations with many steps by reducing the data passing and thread context switching overhead.
To sort data rows in a specific time frame or by a specific number for real-time streaming.
To process chunks of data, pause, and then continue processing after reaching the chunk size.
