Viewing Match Performance Analysis Data

Viewing Match Performance Analysis Data

You can view statistical data on the record groups that the mapping reads as input data.
To view the data, right-click the Match transformation in the mapping canvas and select
Match Performance Analysis
.
Before you run the analysis, validate the mapping that contains the transformation.
Match performance analysis displays data for the following properties:
Property
Description
Source
The number of input data rows.
Last run
The date and time of the analysis.
Total number of discovered groups
The number of groups defined for the data set, based on the selected group key value.
Throughput (records per minute)
Variable value that estimates the speed of the match analysis. You set this value. Use the value to estimate the time required to run the match analysis.
Estimated time to match records
The time taken to analyze all records in the data set, based on the Match transformation configuration.
Total number of pairs generated
The number of comparisons that the transformation must perform, based on the number of input data rows and the number of groups.
Minimum group size
Variable value that indicates the minimum number of records a group can contain. You set this value. Use the value to verify that the mapping will create groups of a usable size.
The minimum group size value does not determine the size of the groups created when the mapping runs.
Number of groups below minimum threshold
The number of groups that contain fewer records than the minimum group size value.
If many groups are below the minimum group size, you might need to edit the transformation and select a different group key.
Maximum group size
Variable value that indicates the maximum number of records a group can contain. You set this value for the performance analysis. Use the value to verify that the mapping will create groups of a usable size.
The value does not determine the size of the groups created when the mapping runs.
Number of groups above maximum threshold
The number of groups that contain more records than the maximum group size value.
If many groups are above the maximum group size, you might need to edit the transformation and select a different group key.
