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

Show HN: CozoDB, Hybrid Relational-Graph-Vector DB, the Hippocampus for LLMs
I have been thinking about adding FTS to CozoDB for a long time but resisted the temptation so far. The reason is that text search is language-specific: what works for one language does not work for another. There is simply no way that CozoDB can duplicate the work of a dedicated text search engine for all the languages in the world.
Our current solution is to use mutation callbacks to synchronize texts to a dedicated text search engine. This is language specific: for example, for python: https://github.com/cozodb/pycozo#mutation-callbacks , and for Rust: https://docs.rs/cozo/latest/cozo/struct.Db.html#method.regis...

For folks looking for documentation or getting started-examples, see:
- The tutorial: https://nbviewer.org/github/cozodb/cozo-docs/blob/main/tutor...
- The language documentation: https://cozodb.github.io/current/manual/
- The pycozo library README for some examples on how to run this from inline python: https://github.com/cozodb/pycozo#readme
What are some alternatives?
cozo - A transactional, relational-graph-vector database that uses Datalog for query. The hippocampus for AI!
souffle - Soufflé is a variant of Datalog for tool designers crafting analyses in Horn clauses. Soufflé synthesizes a native parallel C++ program from a logic specification.
sonic - 🦔 Fast, lightweight & schema-less search backend. An alternative to Elasticsearch that runs on a few MBs of RAM.
datascript - Immutable database and Datalog query engine for Clojure, ClojureScript and JS
blog - Some notes on things I find interesting and important.
differential-datalog - DDlog is a programming language for incremental computation. It is well suited for writing programs that continuously update their output in response to input changes. A DDlog programmer does not write incremental algorithms; instead they specify the desired input-output mapping in a declarative manner.
