Key value that identifies the group to which the record belongs.

Downstream transformations such as the Association transformation can read the group key value.

The identifier of the cluster to which the record belongs. Used in cluster output.

The number of records in the cluster to which a record belongs. When a cluster contains a unique record, the cluster size is 1. Used in cluster output.

A unique row identifier for the record. The Match transformation uses the row identifier to identify the row during the match analysis operations. The identifier might not match the row number in the input data.

The row identifier of the driver record in a cluster. Used in cluster output. The driver record is the record in the cluster with the highest value on the SequenceID input port.

The transformation assigns a driver score in matched pair output and clustered output. In a matched pair, the driver score is the match score between the pair of records. In a cluster, the driver score is the match score between the current record and the driver record in the cluster.

The row identifier of the record that matched with the current record and linked it to the cluster. Used in cluster output.

The match score between two records that results in the creation of a cluster or the addition of a record to a cluster. The LinkID port identifies the record with which the current record shares the link score. Used in cluster output.

An eight-character code that represents the results of the match analysis on an input record. Used in single-source identity analysis when the transformation compares the data source to an index data store.

The transformation populates the first three characters in the code. The transformation can return different characters at each position. The transformation returns 0 for positions four through eight.

When you configure the transformation to generate matched pair output, the transformation creates a PersistenceStatus port and a PersistenceStatus1 port.

A text description of the persistence status code values. Used in single-source identity analysis when the transformation compares the data source to an index data store.

When you configure the transformation to generate matched pair output, the transformation creates a PersistenceStatusDesc port and a PersistenceStatusDesc1 port.
