Netflix’s Distributed Counter Abstraction

Netflix's Distributed Counter Abstraction, leveraging the TimeSeries Abstraction for scalable and low-latency distributed counting, tackles the challenges of real-time count accuracy and infrastructure cost management, with configurable "Best-Effort" or "Eventually Consistent" modes, supported by EVCache, idempotency keys, and a sophisticated rollup aggregation process to balance performance, accuracy, and resource allocation, processing close to 75K requests per second globally.
