AEP technical foundation question event

[Michael_Soprano]

Hi, 

Why the second answer is correct? It is because the id of the event is not unique?

Yes. Only 1 record will be available in profile with a given _id. Second record won’t be processed to profile.

Hi @Michael_Soprano  - In the AEP experience, an event's _id serves as its unique identifier. It is not possible to store multiple events with the same _id in the profile storage. If an event is ingested with an _id that already exists, it will not be added to the profile store. Consequently, the number of events associated with a profile will remain one. It's important to note that events sharing the same _id will still be ingested into the data lake. You can view all events with the same _id by running a query on the dataset. However, only the first event bearing that _id will be stored in the profile store.

Thanks,
