Match Output Properties

Match Output Properties

The Match Output view includes properties that specify the cache memory behavior, the match score threshold, and the match scores that appear in the transformation output.
You can also use the match output properties to specify how the transformation adds match score values to the output records.
After you select a match output type, configure the following properties:
Cache Directory
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.
Cache Size
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.
If you enter a value of 65536 or higher, the transformation reads the value in bytes. If you enter a lower value, the transformation reads the value in megabytes.
Threshold
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.
Scoring Method
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.
If you add the driver score to the records, you increase the mapping run time. The mapping waits until all clusters are complete before it adds the driver score values to the records.
