You can use the post-merge-review option with the Merge clustering method. If a search returns any accepted match records, the post-merge-review option merges all the clusters that have accepted match records and flags the merged cluster. Use Informatica Data Director to manually review the details of the flagged cluster. You can split the merged cluster or retain it as a single cluster.
For example, you have a record with John as the name in cluster 1 and another record with Samuel as the name in cluster 2. Add a record with John Samuel as the name to the source table.
During synchronization, the record of John in cluster 1 matches the record of John Samuel and the records have an accepted score between them. The Merge method adds the record of John Samuel to cluster 1. The record of John Samuel in cluster 1 matches the record of Samuel in cluster 2 and the records have an accepted score between them. The Merge method merges cluster 2 with cluster 1, and the post-merge-review option flags cluster 1. Use Informatica Data Director to manually review the details of cluster 1.
