Data Lake
Adobe Experience Platform Data Lake
The Data Lake is the queryable history in AEP, where datasets live and what Query Service and Data Distiller work against. The Profile Store, by contrast, is the live view used by audiences, journeys, and activation.
- When it applies
- It is the place for data that will be audited, rebuilt, or analyzed later: the state snapshot a nightly job computes, the history of what each customer was shown, anything someone will query with SQL.
- What it is confused with
- A journey writing to the profile does not land it in the lake. Profile writes from Journey Optimizer go only to the Profile Store, so the field exists instantly for the app and for audiences while staying invisible to Query Service until a batch process lands it.
- Architecture consequence
- The call is made per datum, not by habit: what gets audited or analyzed has to reach the lake, what only segments lives in Profile, and an ephemeral flag that merely branches one node should not be persisted in either.
