To conclude the series on using #NDB interpreted code (IC) programs with #RonDB I decided not to write more blog posts but rather two formal research papers, which I presented at The 19th European #Lisp Symposium (#ELS'26), Krakow, 11-12 May 2026. #Dydra

@lisp_mgr I just noticed that I should have called this paper "A Lisp Dialect for RonDB Interpreted Code", as this is specific to #RonDB and will not work with plain #NDBCluster anymore. @RonDB_ai @mikael_ronstrom

My second paper "A Lisp Dialect for NDB Interpreted Code" I'll present at European Lisp Symposium 2026 tomorrow at 16:00 CEST.

This is the third article in a series on using #NDB interpreted code (IC) programs with @RonDB_ai and discusses an example of a very short but still very useful interpreted code program. It describes the actually essential implementation for Dydra.

This is the second article in a series on using #NDB interpreted code (IC) programs with #RonDB and it just tries to work out how accurate the #MySQL documentation still is for its fork RonDB. A question that I had for a long time.

I just added a small new section on native code produced by the Common Lisp compiler, in this case #SBCL for x86-64 on Linux.

[Datagraph GmbH / Dydra.com @dydradata]

This is the first article in a series on using #NDB interpreted code (IC) programs with #RonDB. And how the compiler I wrote for it made the task much simpler. Allowing not only to compile to NDB interpreted code but also to a #Lisp backend for debugging.

Mikael Ronström (@mikael_ronstrom), Head of Data at @Hopsworks AB, published a new blog article on our collaboration: #CommonLisp comes to #RonDB.

Read our new article:
Scaling Dydra with RonDB: Toward a Trillion-Triple Store

What if your #database could remember everything—every edit, every state, every version—across time, while scaling effortlessly beyond the limits of a single machine?

https://t.co/j62zeL3phB

[Datagraph GmbH / Dydra.com @dydradata]

That’s exactly the kind of challenge we’ve been tackling with #Dydra, a revisioned #RDF graph store, and #RonDB, a high-performance, clustered database built for scale.

https://t.co/j62zeL3X79

[Datagraph GmbH / Dydra.com @dydradata]

After more than a year of work, we just released a much enhanced version of our #CommonLisp bindings to the C++ #NDB API of #RonDB.

So, welcome cl-ndbapi for RonDB 24.10!

https://t.co/uw3K2mXV5G

We are currently working on a series of articles, how we use it to scale #Dydra.

[Datagraph GmbH / Dydra.com @dydradata]

If you need #persistence for native #JavaScript applications, guaranteed eventual #consistency for multiple clients and all data stored in #revisioned data repositories, have a look at our JavaScript web client interface to the #Dydra #RDF service:
https://t.co/aZHWXANJEJ

[Datagraph GmbH / Dydra.com @dydradata]

Conflicting changes by multiple clients can be resolved with Conflict-free Replicated Data Types (#CRDT).
#Dydra offers such types, so that data can be replicated and reconciled among multiple clients, as we presented already at the @MEPDaW Workshop 2019: https://t.co/nqsBZeaxRg

[Datagraph GmbH / Dydra.com @dydradata]

Did you know that our #JavaScript web client library can act as a #replication node of the #Dydra graph store?
This means, all changes are automatically pushed to your web client applications (background change notification). See https://t.co/aZHWXANJEJ

[Datagraph GmbH / Dydra.com @dydradata]

@AndriusDauksa @namedgraph @larsga You'll find the #Dydra API documentation at https://t.co/tAkfauHK6F.
Depending on your application, you might also want to use the #JavaScript web client interface to the Dydra #RDF service at https://t.co/aZHWXAOhuh It also supports persistence, #CRDT replication and more.

[Datagraph GmbH / Dydra.com @dydradata]

@AndriusDauksa @namedgraph @larsga you should by now have the access code to create and account on https://t.co/AZBsfGm0Rw. there are two things to consider. first, our service provides just rdf storage so your application hosting must continue where it is. second, the api is primarily http-based.
