Filter Optimizations

Filter Optimizations

Filter optimization increases performance by reducing the number of rows that pass through the mapping. The Data Integration Service can apply the early selection optimization or push-into optimization.
When the Data Integration Service applies a filter optimization method, it moves a filter as close to the source as possible in a mapping. If the Data Integration Service cannot move a filter before a transformation in a mapping, it might be able to push the filter logic into a transformation.
