Design a high-level architecture for a low-latency, high-frequency trading platform. Specifically address how you will handle the CAP theorem (Consistency, Availability, Partition Tolerance). 1) Choose which two properties you prioritize and justify why for this specific domain. 2) Detail the data replication strategy. 3) Explain how the system handles network partitions to ensure data integrity or fast failover. 4) Describe the mechanism for message queue durability to prevent loss of trade orders.
