Without build optimizations (incremental builds, caching, we will get to those soon) this will eventually become unmanageable as well — think about going through all images in a website: resizing, deleting, and/or creating new files over and over again. It is not possible to ship code incrementally.

Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged. Table-valued functions use a table variable, which can be used to cache and replay results in suitable circumstances. Spools are the least costly way to cache partial results.

Have we optimized enough with tree-shaking, scope hoisting, code-splitting, and all the fancy loading patterns with intersection observer, progressive hydration, clients hints, HTTP/3, 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.

If the web font isn’t available then, we fall back to the fallback font, but the next page navigation (or a reload of this page) will use the font — as it should have finished downloading now. The amount of code isn’t huge, but it still feels like a little bit more effort than it should be. When Can We Start Using This?

The general idea is to cache and replay results, saving repeated executions of inner-side operators wherever possible. When a spool is able to replay cached results, this is known as a rewind. You may find it helpful to think of a spool rebind as a cache miss, and a rewind as a cache hit. Lazy Table Spool.

It’s widely accepted that self-hosted fonts are the fastest option: same origin means reduced network negotiation, predictable URLs mean we can preload , self-hosted means we can set our own cache-control. There a lot of techniques combined here, but the resulting code is still slim and maintainable enough that it should’t pose a problem.

Total elapsed time is 933ms with 6,673ms of CPU time with a warm cache. The stopwatch starts when SQL Server enters the code for an operator from its parent, and stops (but does not reset) when that code leaves the operator to return control back to the parent (not to a child). Let’s be precise about what we’re measuring here.

An SSG offers a middle ground between a complex yet modular CMS solution and a simple yet involved hand-coded HTML site. Due to strong templating support, a website managed by SSG can be truly modular.
