Determines the number of threads that the transformation uses at run time.

The Match transformation uses a single execution instance in field match analysis. You can edit the number of execution instances when you configure the transformation for identity match analysis.

Determines whether the transformation applies the comparison algorithm in a match strategy to pairs of identical records in the input data.

When the transformation finds a pair of identical records, the algorithm does not need to analyze the levels of similarity between the records. The transformation can pass the records directly to the output stage without additional analysis. To configure the transformation to pass the identical records directly to the output stage, select Filter Exact Match. When the input data contains many identical rows, the comparison algorithm performs fewer calculations, and the mapping runs faster.

Select the option when the input data contains many identical rows. Do not select the option if the input data does not contain many identical rows, as the transformation might run more slowly.

Amount of detail that appears in the log for this transformation. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.
