Defining high availability In general terms, high availability refers to the continuous operation of a system with little to no interruption to end users in the event of hardware or software failures, power outages, or other disruptions. If a primary server fails, a backup server can take over and continue to serve requests.

More specifically, we’re going to talk about storage and UI differences, which are the ones that most often cause confusion to developers when writing Flutter code that they want to be cross-platform. Running Different Code On Different Platforms. In this article, we’re going to see some of those differences and how to overcome them.

SQL Server relies on Forced-Unit-Access (Fua) I/O subsystem capabilities to provide data durability, detailed in the following documents: SQL Server 2000 I/O Basic and SQL Server I/O Basics, Chapter 2. Device level flushing may have an impact on your I/O caching, read ahead or other behaviors of the storage system. Device Flush.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? It’s much easier to reach performance goals when the code base is fresh or is just being refactored.

Is it worth exploring tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, server push, clients hints, HTTP/2, service workers and — oh my — edge workers? How do we actually know where we stand in terms of performance, and what our performance bottlenecks exactly are?

And suddenly, before you know it, the code base gets a little bit overweight and fragmented , third-party scripts have to load just a little bit earlier, and shiny new dynamic content finds its way into the DOM through the backdoors of fourth-party scripts and their uninvited guests.

This isn’t true (more on that in a follow-up post), and sites which are built this way implicitly require more script in each document (e.g., The server sends it as a stream of bytes and when the browser encounters each of the sub-resources referenced in the document, it requests them. for router components).

More importantly, if this works out well, this could lead to a radical improvement in performance by leveraging hardware trends such as GPUs and TPUs. They demonstrated that neural nets based learned index outperforms cache-optimized B-Tree index by up to 70% in speed while saving an order-of-magnitude in memory. Learned indexes.

This uses hardware, typically a crystal oscillator, that produces ticks at a very high constant rate regardless of processor speed, power settings, or anything of that nature. Total elapsed time is 933ms with 6,673ms of CPU time with a warm cache. SQL Server uses the high-precision QueryPerformanceCounter API to capture timing data.

Some examples of the latter are heavily cached websites, as well as single-page apps that periodically fetch small updates via APIs and other protocols such as DNS-over-QUIC. Some options for doing this are described in the IETF’s proposed document. We can also expect QUIC-specific hardware to become available.
