Book Seller External Fan-Out Broker Service
4/5This distributed systems design interview question from Databricks asks you to architect an external fan-out broker service that queries dozens of third-party APIs concurrently to find the best price for customers. You will need to address high-scale concurrency, asynchronous communication, timeout handling, and fallback pricing logic within a robust architecture. The scenario evaluates your capability to build resilient systems that depend on external, unreliable services. The full architectural breakdown and expert solution require a subscription.
