Data Vault’s biggest selling point is that it tracks history perfectly. Its biggest drawback is that querying that history (using LoadDate and LoadEndDate) requires writing complex, performance-heavy queries. Testing if your Data Vault actually matches the source at a specific point in time is incredibly difficult.
What to add: Automated "As-Of" Reconciliation. A feature that automatically samples a source table from a week ago, queries the generated Data Vault using an AS OF point-in-time logic, and runs a automated diff to prove the Vault is structurally accurate.
Why it lowers frustration: It gives data architects immediate, mathematical certainty that their Data Vault isn't silently dropping history or duplicating rows.
