CJA stitching methods

[Harveer_SinghGi1]

Hi Team,

Need some help in understanding what is the benefit of using Graph-Based stitching over Field-Based stitching for CJA?

I was under the impression that with graph stitching if user have a linkage between persistent id and transient id in the graph, they don't require to login during the lookback window for stitching to work on the events recorded during that period, stitching should be able to take the persistent id and the transient id namespace and fetch the linked transient id from graph. But the documentation states that user has to authenticate withing the lookback window for both the methods. If that is the case, What is the benefit of graph based stitching over field based stitching? I'm anyway required to record the authentication during the lookback window, I can record my transient id also on the authenticated events and use field based stitching, how is graph based stitching better/different o field based stitching?

Cheers!

The key benefit is that the persistent id and transient id do not need to be present on the exact same record from AEP. You can have a record that links ID1 to ID2 and another record elsewhere that links ID2 to ID3. Then, if you need to look up ID3 from ID1, the Graph based stitching approach can do that, where you would have to manually crosswalk the IDs if you only had field-based stitching (because the two IDs would need to show up in the same dataset). That will work for all records going forward, and the lookback window can use the graph to restate the data with that match.
