Do TTL for profiles affect CJA stitching?

[JaniceAk]

Hi,

I'm wondering if a TTL (time to live) for specific type of events within profiles in AEP (leveraged by both Audience Manager and CJA) affect what events are being used to stitch identities for CJA? Wondering if, when a TTL is established for profile events from a dataset, and it eliminates events from the dataset in profiles that would be needed as reference for stitching-- past that TTL time range-- would it indeed affect graph-based stitching in CJA? I.e. even though X days ago someone's ID got stitched w primary ID in their profile, once the TTL hits after that X days then the stitching reference goes away.

Or, does the TTL does not affect how graph-based stitching is done for CJA, and it only affects the events that appear for a profile when building an audience in Audience Manager?

Hi @JaniceAk 

The TTL setting applies to how long certain profile events or attributes are retained in AEP and Audience Manager for audience evaluation. Once the TTL period expires, those events no longer appear in the profile for segmentation or activation purposes.

However, this does not undo or break identity stitching in CJA. When an identity link is first established (for example, when a device ID is stitched to a primary customer ID), that relationship is stored in the identity graph. The identity graph maintains those connections independently of TTL rules, so even if the original event that created the link is no longer visible in the profile, the stitching itself remains intact for analysis in CJA.

In short, TTL affects what you see and use when building audiences in AEP or Audience Manager, but it does not retroactively impact the way CJA resolves identities once they’ve been stitched.
