Prerequisites

Section titled “Prerequisites”
  • Warehouse tables modeled and documented (entities, metrics).
  • Destination tool access and field mapping.
  • Data contracts and refresh cadence.

Steps

Section titled “Steps”
  1. Select entities to sync (accounts, users, events, scores); define primary keys.
  2. Build modeled views for each destination schema; add incremental logic.
  3. Configure sync tool (or custom job): mappings, upsert keys, and schedule.
  4. Add field-level validations and row-level change detection.
  5. Set alerts on failures, drift, and freshness breaches.

Validation

Section titled “Validation”
  • Row counts and key coverage match expectations; no PII leaks beyond policy.

Troubleshooting

Section titled “Troubleshooting”
  • Duplicate records: fix keys and dedupe logic.
  • Stale data: adjust schedule or incremental watermark.

Time/Impact

Section titled “Time/Impact”
  • 2–6 hours per entity. Unlocks personalization and activation use cases.
