Using a Filter Transformation

Using a Filter Transformation

You can use a Filter transformation in the mapping to measure the time it takes to read source data.
Add a Filter transformation after each source qualifier. Set the filter condition to false so that no data is processed passed the Filter transformation. If the time it takes to run the new session remains about the same, you have a source bottleneck.
