✨ This talk was recorded at Lambda Days in June 2024. If you're curious about our upcoming event, check https://lambdadays.org ✨ At some point, a business may reach a stage where app logic should be executed based on specific conditions like location, app version, or user type. For example, you may have to dynamically change discounts to sell leftover stock or limit low-profit requests during peak hours. Each new “crazy” idea from your manager often means coding, understanding needs, and system load with frequent redeployments. From a business perspective, as a manager, you want the ability to control the system's behavior without struggling through endless discussions, tickets, and running a full development cycle. We will design a rule matcher to manage changing conditions in real-time in a user-friendly manner. It will use any app traffic attribute, verify rule validity, and keep rules easy to read and manage. We will leverage the capabilities of Scala and recursion schemes to create a fast and efficient solution that can be integrated into any app. Let's keep in touch!
