Temporal's Entity Workflow pattern offers a clean solution for loyalty program management at scale. Instead of relying on shared databases with locking, retry logic, and cron jobs, each customer gets their own dedicated, durable Workflow identified by their customer ID. This workflow holds points balance, tier status, and activity history in memory. Signals handle point accruals, Updates validate and apply redemptions synchronously, and Queries read current state without database access. Tier upgrades happen inline as business logic rather than via nightly batch jobs, and the workflow can run for years while automatically managing internal history limits.
