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.

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.

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

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.

The Ten Rules of Schema Growth
Datahike [0] provides similar functionality to datomic and is open source. It lacks some features however that Datomic does have [1].

Is Datomic right for my use case?
You can also consider other durable Datalog options like datahike or datalevin which can work either as lib (SQLite style) or in a client-server setup; if you want to play with bi-temporality XTDB is a rock solid option with very good support and documentation.

Max Datom: Interactive Datomic Tutorial
Oh really interesting. I didn't know about that. I was actually going threw the old Mendat code base and was considering using that.
I would really like a pure Rust version of Datomic for embed use cases.
There is all also Datahike, that is going in that direction too. It is maintained and actively developed.

Show HN: Matrix-CRDT – real-time collaborative apps using Matrix as backend
Having an Datomic like store backed by something like this.
https://github.com/replikativ/datahike
Is an Open Source variant of Datomic.
Lambdaforge wants to eventually have this work with CRDTs.
Using the Matrix ecosystem for this is quite interesting as it solves many problems for you already.

Ask HN: Why are relational DBs are the standard instead of graph-based DBs?
Unlike some other commenters, I agree that graph models are usually a better fit for most data than relational models. There's been some interesting work in recent years developing this idea: in the Clojure world there's Datomic, XTDB, and a host of competitors, all of which build on work from Semantic Web/SPARQL/triplestores and logic programming. Some are even intended to be used as primary datastores: they support some amount of schema and constraints, have well-defined consistency and ACID guarantees, etc. This makes them unlike graph databases like Neo4J and others, which fill an architectural role more like Elasticsearch as a read-optimization tool. Here's an interesting talk making a case for triple-based databases.
