Merge policies

[hrya]

Hi, 

How the merge policies required for the segment. In segment builder there is the merge policies details getting used shown and also while retrieving the segment details using the API payload contains merge policies used which is different everytime, on what basis the merge policies gets selected while the segment is created?

During segment creation, you have the option to explicitly select a merge policy to be used for that segment. This overrides the default merge policy and allows you to choose the appropriate merge policy based on your segmentation requirements.

If no specific merge policy is selected during segment creation, the default merge policy set for your organization will be used. Each organization can have one default merge policy defined for each schema class (e.g. XDM Individual Profile).

Merge policies are rules used by Profile to determine how data will be prioritized and combined into a unified view under certain conditions. When data is ingested from various sources, it often contains information about the same customer but with potential conflicts or inconsistencies.

Merge policies determine how these conflicts are resolved and which data takes precedence when creating a single, unified profile for each customer.

I hope this makes sense.
