If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Our distributed tracing infrastructure is grouped into three sections: tracer library instrumentation, stream processing, and storage.

Back in 2017 the engineering team at Facebook had a problem. The initial version of Delos went into production after eight months using a ZooKeeper-backed Loglet implementation, and then four months later it was swapped out for a new custom-built NativeLoglet that gave a 10x improvement in end-to-end latency. Every little helps!

Today marks the 10 year anniversary of Amazon's Dynamo whitepaper , a milestone that made me reflect on how much innovation has occurred in the area of databases over the last decade and a good reminder on why taking a customer obsessed approach to solving hard problems can have lasting impact beyond your original expectations.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The Moto G4 , for example. Here begins our 2021 adventure. Hard Reset.

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. Both of these Intel processors are special bespoke models that are not in the Intel ARK database. Since then, Microsoft has changed the naming of this series to Lsv2. Memory (GiB).

Chrome has missed several APIs for 3+ years: Storage Access API. WebGL 2 launched for other platforms on Chrome and Firefox in 2017. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. Where Chrome Has Lagged. The underlying graphics capabilities from OpenGL ES 3.0

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Depending on how much dynamic data you have, you might be able to "outsource" some part of the content to a static site generator , pushing it to a CDN and serving a static version from it, thus avoiding database requests.
