Replaying match rule without having to change how I load source data

Here is our current situation:

Our xDM implementation has been running smoothly for several months
We recently created a new high-scoring match rule and improved our survivorship rules
We have match groups with goldens created under earlier lower-scoring match rules. These groups are overmatched, with poor survivorship outcomes.
When our source data changes and the middleware loads it to Semarchy and submits the Semarchy consolidation job with the updated masters, We want the updated masters to be re-grouped into smaller match groups, dis-associating from the old overmatched groups.

What is the best way to do this? Can we do it by changing config settings such as the matcher to avoid having to code new source data loaders.

Hello Ulises,

Not knowing all of your context, I will only provide insights based on my understanding of your situation.

It sounds to me that the preferred way, would be to replay matching on your MDM following the configuration of those new rules (matching and survivorship).

This way, any new data would match according to the new rules on the redefined groups (following the replay).

Here is the documentation link on how to replay matching: https://www.semarchy.com/doc/semarchy-xdm/xdm/latest/Integrate/manage-duplicates-with-sql.html#_replay_matching

Hope this helps.

Good luck
