This blog is in reference to our previous ones for ‘Innodb Performance Optimizations Basics’ 2007 and 2013. Although there have been many blogs about adjusting MySQL variables for better performance since then, I think this topic deserves a blog update since the last update was a decade ago, and MySQL 5.7

On July 5th 1982, Leslie Lamport (initial LaTeX developer, Microsoft Researcher and winner of the 2013 Turing Award), Robert Shostak and Marshall Pease published a paper named The Byzantine Generals' Problem. Because these are real-time systems, their Byzantine fault tolerance solutions must have very low latency.

You saw the first iteration in April 2013 with the launch of Local Secondary Indexes (LSI). So when we launched in January 2012, we provided simple query functionality that used hash primary keys or composite primary keys (hash + range). Since then, we have been working on adding flexible querying.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Browser release notes and caniuse tables since Blink forked from WebKit in 2013 [7]. have been available in iOS since 2013 with iOS 7.0. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. Browsers sometimes ship new, desirable features simultaneously (e.g.,

Since it is potentially unbounded, we can’t wait—buffer elements—until we have received all data before we act upon it, but need to do so in an incremental fashion—ideally without overwhelming ourselves, or overwhelming those who consume the data we produce or incur a too-high processing latency.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
