Using the collected statistical metrics, we can establish a latency SLI (Service Level Indicator) and set up a latency SLO (Service Level Objective) based on Google SRE practices. We can compute the percentage of requests that fall under a time-bucket criterion, e.g., less than 200 ms. For instance, we need them to calculate percentiles, e.g., 90p, 99p, etc. Statistical metrics such as histograms and summaries are essential and complex at the same time. One of the challenges when using Kotlin coroutines is their observability, such as measuring execution time, recording latency buckets, and publishing statistical metrics. Consequently, threads can run in either concurrent or parallel ways. On the other hand, threads are based on the concept of preemptive multitasking that involves interrupts, a scheduler, and an operating system. Thus, they don't depend on a scheduler and operating system. Other coroutines can then use it to start/continue their execution. Coroutines are lightweight cooperative multitasking, often referred to as ' lightweight threads.' They yield control upon suspension. Coroutines themselves have been around since the 1960s. Kotlin coroutines are cooperative subroutines that can suspend and resume their execution at any suspension point (awaiting a result). routines is one of the asynchronous (and concurrency) libraries in Kotlin for writing asynchronous, non-blocking code. ![]()
