Web25 Feb 2024 · For instance, your latency objective could be expressed as: “I would like to get 99th percentile end-to-end latency of 50 ms from Kafka.”. This adds to your availability, durability, and throughput goals. Achieving high durability and high throughput have known latency trade-offs. The challenge is to scale an application for throughput ... Weblag behind others. Since the latency of such massively parallel programs depends on the slowest process, enormous run-time variations often lead to signicant performance degradation. This effect is known as the tail latency problem (a.k.a. the tail-at-scale effect) and is a dominant bottleneck in interactive web applica-tions [14, 4, 1, 8, 11].
