    recently delved into Vector's Adaptive Request Concurrency (ARC) mechanism, which dynamically adjusts request rates based on real-time system metrics. This approach, inspired by TCP congestion control algorithms, optimizes throughput and maintains system stability without relying on static rate limits. Also found another video talking about this method - SREcon23 Americas - Adaptive Concurrency Control for Mixed Analytical Workloads https://youtu.be/-UDeh-kBRbc
