| Stage | Description |
|---|---|
| Best of Breed | This stage selects a best-of-breed record from the duplicates cluster by selecting a template record, then using that record to build a composite record that becomes the survivor record. |
| Candidate Finder | This stage finds candidate records that will form the set of potential matches that the Transactional Match stage will evaluate. Candidate Finder is used with Transactional Match. |
| Duplicate Synchronization | This stage allows you to specify fields from a collection of records to copy (post) to the corresponding fields of all records in the collection. |
| Filter | This stage allows you to specify the criteria that records must satisfy to be retained or removed from a collection of duplicate records, either for further processing downstream or for your output file. |
| Group Key Generator | This stage uses a group strategy to create group keys and transitively merge selected fields. |
| Interflow Match | This stage identifies matches between similar data records across multiple input streams. |
| Intraflow Match | This stage identifies matches between similar data records within a single input stream. |
| Match Key Generator | This stage creates a non-unique key shared by all like records. You have the option of grouping records that share the same key for comparison. |
| Transactional Match | This stage matches suspect transactions against a database using the Candidate Finder Stage to query and return potential candidate records. |
| Write to Search Index | This stage enables you to create a full-text index based on the data that the stage is accepting for processing. You can retain data in a dedicated search index to improve response times when searching the Candidate Finder. |
