Specifies the directory to which the Data Integration Service writes temporary data during field match analysis. The Data Integration Service writes temporary files to the directory when the volume of data that the match analysis generates is greater than the available system memory. The Data Integration Service deletes the temporary files after the mapping runs.

You can enter a directory path on the property, or you can use a parameter to identify the directory. Specify a local path on the Data Integration Service machine. The Data Integration Service must be able to write to the directory. The default value is the CacheDir system parameter.

Determines the amount of system memory that the Data Integration Service assigns to field match analysis. The default value is 400,000 bytes.

Before it sorts the data, the Data Integration Service allocates the amount of memory that you specify. If the match analysis generates a greater amount of data, the Data Integration Service writes the excess data to the cache directory. If the match analysis requires more memory than the system memory and the file storage can provide, the mapping fails.

Sets the minimum match score that identifies two records as potential duplicates of each other.

You can assign a parameter to the threshold value. Set a decimal value in the range 0 through 1.

Determines the match score values that appear in the transformation output. Select a scoring method for cluster outputs.

The following table describes the scoring method options:

Scoring Method Option	Description
Both	Adds the link score and the driver score to each record in the cluster.
Link Score	Adds the link score to each record in the cluster. Default option.
Driver Score	Adds the driver score to each record in the cluster.
None	Does not add a match score to any record in the cluster.
