TAIL LATENCY MIGHT MATTER MORE THAN YOU THINK

Summary from the TLDR newsletter

Tail latency, or high-percentile latency, refers to high latencies that clients see fairly infrequently. Modern architectures tend to have a lot of components, so these rare instances of latency can still have a large impact. This article looks at the different ways tail latency can affect projects. Developers should be aware of service latency and consider monitoring common customer or client use cases for their end-to-end latency experience.
