Match Mapping Performance

Match Mapping Performance

You can preview the data factors that determine the performance of the Match transformation before you run the mapping that contains the transformation. You can verify that the system has the resources to run the mapping. You can also verify that you configured the transformation correctly to measure the levels of similarity in the input data.
Use the
Match Performance Analysis
option to verify that the system has the required resources. Use the
Match Cluster Analysis
option to verify that the mapping can accurately measure the levels of similarity in the input data.
Run match performance analysis and match cluster analysis on any Match transformation that reads a single data source. Run match performance analysis on any Match transformation that performs dual-source field match analysis. Do not run match performance analysis or match cluster analysis on an identity match strategy that connects to index tables.

Drill-down on Match Performance Analysis

You can drill down on the match analysis data to view the record pairs that meet or exceed the match threshold. Double-click a record in the
view, and use the Data Viewer to view the records that match the record that you select. The Data Viewer displays the data for each pair of records on a single row. The row contains the row identifier of each record in the pair.

Drill-down on Match Cluster Analysis

You can drill down on the cluster analysis data to view the records in each cluster. Double-click a cluster in the
view and read the data in the Data Viewer. The Data Viewer displays one cluster at a time. The cluster data includes the score options that you selected, such as the driver score, link score, driver identifier, or link identifier.

Match Transformation Logging

When you run a mapping that uses a Match transformation, the Developer tool log tracks the number of comparison calculations that the mapping performs. To view the log data, select the
Show Log
option in the Data Viewer.
The mapping updates the log every 100,000 calculations.
