Souffle and Cozo mentioned below already implement the whole of "traditional" datalog.
Percival (https://github.com/ekzhang/percival) has some very nice examples showing how you can interactively write and test rules on top of a datalog interpreter.
Bud (http://bloom-lang.net/bud/) is Hellerstein's proof of concept playground. It has bit-rotted in the past few years, but the examples are readable even if you can't easily get it working.
The complexity can be quite good. You can syntactically determine when you've written linear recursion (equivalent to a for loop) vs not. Otherwise, the complexity is what you'd expect from incremental view maintenance in a normal SQL database. Which is to say O(n^k) with k being the number of relations joined, but usually much, much less with appropriate indexes and skew in the data. All the usual tricks concerning data normalization and indexes from databases apply.
Project mention: Meet RayQL - A Schema and Query Language for Your SQLite Side Projects | dev.to | 2024-04-30That's why I created RayQL, a schema definition and query language for SQLite, built with Rust. The core goal is to provide a compact and familiar syntax that eliminates the need to reinvent the wheel for data validation, allowing you to quickly prototype and build backends without juggling multiple components. With RayQL, everything you need lives in a single executable, which makes it super-easy to get started on your side projects.
Project mention: What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented? | /r/rust | 2023-06-09This is exactly what I needed when implementing xml-mut :D I have used roxmltree instead and manipulated text directly. will try to rewrite it using Xot.
