Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The "missing" graph datatype already exists. It was invented in the '70s
You can without too much work transpile datalog to SQL. SQL does have such strong support that it is useful https://github.com/philzook58/snakelog or perhaps just do it manually https://www.philipzucker.com/tiny-sqlite-datalog/

Show HN: Cozo – new Graph DB with Datalog, embedded like SQLite, written in Rust
Very cool! I love the sqlite install everywhere model.
Could you compare use case with Souffle? https://souffle-lang.github.io/
I'd suggest putting the link to the docs more prominently on the github page
Is the "traditional" datalog `path(x,z) :- edge(x,y), path(y,z).` syntax not pleasant to the modern eye? I've grown to rather like it. Or is there something that syntax can't do?
I've been building a Datalog shim layer in python to bridge across a couple different datalog systems https://github.com/philzook58/snakelog (including a datalog built on top of the python sqlite bindings), so I should look into including yours

Datalog in 100 lines of JavaScript (2022)
Hi pests, I don't think the criticism in the comments gives a full picture.
I wrote about a particular flavor of datalog, in common use today. [1] [2]. The earliest representation I know, which matches the syntax of my essay, was in SICP [3]
There's another, more academic form of datalog, which looks a lot more like prolog. Both have lots of similarities: both systems have a set of facts and rules. Both systems have can take a partially filled fact or rule, and find all matching facts. The more academic flavors of Datalog are useful for general logic, and particularly powerful for recursive questions. The variant I showed is more tailed for database queries.

There is also datascript as a similar option.

What's the use case for relic? Sounds similar to https://github.com/tonsky/datascript ?

This look nice !
Datascript seems to be another Datalog engine (in memory only)

Ergonomic inline SQL as a Python library
Inspired by past work: LINQ, inline-python, crepe, DataScript, Riffle.

Working with large maps
An in-memory database like Datascript may be worth looking into. Otherwise you could take an indexing approach: put all the data into one big map indexed by some unique key, and have a bunch of supplementary indexes that are updated on insertion.
What are some alternatives?
pycozo - The Python client and Jupyter helper for CozoDB
asami - A graph store for Clojure and ClojureScript
cozo - A transactional, relational-graph-vector database that uses Datalog for query. The hippocampus for AI!
datahike - A durable Datalog implementation adaptable for distribution.
datalevin - A simple, fast and versatile Datalog database
10000-markdown-files - 10,000 markdown files. Useful for stress testing note-taking tools.
xtdb - An immutable database for application development and time-travel data compliance, with SQL and XTQL. Developed by @juxt
Apache AGE - Graph database optimized for fast analysis and real-time data processing. It is provided as an extension to PostgreSQL. [Moved to: https://github.com/apache/age]
