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 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.
- datahike for reagent SPA?

Open source Datomic?

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.

What is Lightning Memory Mapped Database (LMDB)?
I may have jumped the gun for the list of programming languages, because I found the list right before you sent this. I am currently on the github readme for node. https://github.com/Venemo/node-lmdb. I really appreciate it. Thank you for all the other knowledge too. Hopefully I can figure this out and utilize it.
-
Looking for something like NeDB
If you're up for something interesting, here is a Node adapter for LMDB, or Lightning Memory-Mapped Database, the backing store used by modern OpenLDAP: https://github.com/Venemo/node-lmdb
-
Clojure Datalog Databases
Perhaps this same approach could be resurrected in conjunction with something like https://github.com/Venemo/node-lmdb (which has synchronous APIs...to avoid rewriting DataScript to be async!)
What are some alternatives?
