The Match Output view includes options that specify the output data format. You can configure the transformation to write records in clusters or in matched pairs.
Select one of the following match output types:
Best Match
Writes each record in the master data set with the record that represents the best match in the second data set. The match operation selects the record in the second data set that has the highest match score for the master record. If two or more records return the highest score, the match operation selects the first record in the second data set. Best Match writes each pair of records to a single row.
You can select
Best Match
when you configure the transformation for dual-source analysis.
Clusters
Writes clusters that contain sets of records that link to each other with match scores that meet the match threshold. Each record must match at least one other record in the cluster with a score that meets the threshold.
You can select
Clusters
when you configure the transformation for single-source analysis and dual-source analysis.
Matched Pairs
Writes all pairs of records that match each other with a score that meets the match threshold. The transformation writes each pair to a single row and adds the match score for each pair to each row. If a record matches more than one other record, the transformation writes a row for each record pair.
You can select
Matched Pairs
when you configure the transformation for single-source and dual-source analysis.
