Fluree DB - A datomic like database that I just discovered
How does it compare to, say grakn (renamed https://vaticle.com/, I think?), or draph (https://dgraph.io/), or Ontotext's GraphDB (https://www.ontotext.com/products/graphdb/), or Datomic?

Firebase is Dead: What is the Perfect Database in 2022?
Edge database looks pretty freakin awesome. It basically seems to re-write SQL and Graph databases together to create some new-ish programming language. It takes care of all the problems GraphQL has, and seems to be built separately but on top of postgres. It is really something unique, beautiful, and powerful. They don't have a security layer yet or a cloud hosting environment, but both are in the works. However, postgres still suffers from the scalable problems we all know. If you like unique fetching and strong typing, also check out TypeDB. It doesn't make its own list number because there is not cloud version, middleware, etc. However, worth checking out.

Ask HN: Why are relational DBs are the standard instead of graph-based DBs?
If you find yourself limited by triplestores, there's also a new growing area of development in knowledge engines, which allow edges-of-edges, entailed relations, hypergraph relations, and more of the power you'd get from full logic programming. TypeDB (recently renamed from Grakn) is an example of that type of database.

How Roche Discovered Novel Potential Gene Targets with TypeDB
In the story to follow, David presents how his team at Roche was able to identify potential novel targets that were not identified by Open Targets as highly ranked. This was made possible with TypeDB, which his team used to store the relevant data and then find underlying biological evidence for those new targets.

Need Graph Db Recommendations Lightweight Neo4j
Give the open-source Grakn a look as well (full transparency: I work there), it is an abstraction over a built in-house hypergraph storage engine and persisted layer using RocksDB. It's a logical database with a reasoning engine at the database level. https://github.com/graknlabs/grakn

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.
