Real-time stream processing to perform live activity tracking, data cleansing, metrics generation, and more. You can eliminate the latency issues caused by cold starts — an increase in normal response time when a new instance receives its first request — by using edge-optimized functions that run code closer to users and other projects.

An application programming interface (API) is a set of definitions and protocols for building and integrating application software that enables your product to communicate with other products and services. When monitoring, it’s important to track metrics that describe the vital aspects of an application’s performance.

Another great insight here (which reminds me of discussions of system latency) is that ‘average’ performance (i.e., expectation) is often an insufficient metric, and the system needs to perform well for all task instances. Often the reward function is multi-dimensional and needs to balance multiple sub-goals.

The RDTSCP instruction is partially ordered — it will not execute until all prior instructions in program order have executed. This partial ordering can help expose the execution time of long-latency instructions (such as memory accesses or mispredicted branches) that occur shortly before the final value of the TSC is read using RDTSCP.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”.
