Design Heroku Connect vs API integration for Postgres sync
Real World Scenario
Team needs Salesforce data in Postgres for custom mobile app offline cache debating Heroku Connect vs nightly API export.

• Polling-based sync latency minutes not milliseconds—set expectations
• API export better for one-way analytics copy without bi-directional needs
• Connect handles bulk mapping; custom conflict resolution still required
• Heroku app colocated reducing latency to Postgres
• Monitor Connect sync status and failed row logs
• Compliance: Postgres data residency and encryption requirements
