Loyalty Points with Entity Workflows in Temporal

This post details the application of the Actor Model abstraction using Temporal Workflows for managing loyalty points. It describes how each customer is represented by a dedicated Workflow (entity workflow) that maintains state (points balance, tier status) in memory. Purchases are handled via Signals, redemptions via Updates (with validation), and balance display via Queries. This approach eliminates the need for cron jobs and database locking, ensuring real-time consistency and durability for customer loyalty accounts.
