Configuration DSLs for Spring Boot

Project mention: What's New in Spring Framework 6.1 | news.ycombinator.com | 2023-08-16

The point isn't that one should reinvent the way that Tomcat is started, but that Spring Boot (by default) is using action at a distance and runtime reflection which have serious downsides if you want to understand what's actually going on because you're a) new to the technology, or b) have to debug some weird edge case.
The alternative is using explicit, reflection-less code - which you can do even with Spring, although it's experimental: https://github.com/spring-projects-experimental/spring-fu

sirix

SirixDB is an an embeddable, bitemporal, append-only database system and event store, storing immutable lightweight snapshots. It keeps the full history of each resource. Every commit stores a space-efficient snapshot through structural sharing. It is log-structured and never overwrites data. SirixDB uses a novel page-level versioning approach.

Project mention: Show HN: Integer Map Data Structure | news.ycombinator.com | 2024-01-24

We're using a similar trie structure as the main document (node) index in SirixDB[1]. Lately, I got some inspiration for different page-sizes based on the ART and HAMT basically for the rightmost inner pages (as the node-IDs are generated by a simple sequence generator and thus also all inner pages (we call them IndirectPage) except for the rightmost are fully occupied (the tree height is adapted dynamically depending on the size of the stored data. Currently, always 1024 references are stored to indirect child pages, but I'll experiment with smaller sized, as the inner nodes are simply copied for each new revision, whereas the leaf pages storing the actual data are versioned themselfes with a novel sliding snapshot algorithm.
You can simply compute from a unique nodeId each data is assigned (64bit) the page and reference to traverse on each level in the trie through some bit shifting.
