Customer Workflows in Loyalty Programs with Temporal

This post demonstrates how to implement the Actor Model's core principles (message sending/receiving, state maintenance, actor creation) using Temporal Workflows. It provides a concrete example of a customer loyalty program, detailing the implementation of Signal handlers for 'addPoints' and 'cancelAccount', and the use of `workflow.NewSelector` to manage incoming messages. It also discusses the implications of event history size for long-lived workflows and the use of Continue-As-New.
