Today I created a #Flyway plugin for #neo4j using our #JDBC driver
https://github.com/michael-simons/neo4j-flyway-database
But Michael, aren't you the main author of Neo4j-Migrations?
I sure am and both the latter and the new plugin create the same meta-graph for the migrations and are mostly compatible.

This is really cool and kinda insane—running modern #Perl on the #Java Virtual Machine (#JVM).
Why? Maybe you want the flexibility of Perl scripts in your JVM-based environment (including #Kotlin and #Scala) without shelling out. More reasons here: https://github.com/fglock/PerlOnJava/blob/master/docs/WHY_PERLONJAVA.md
Anything with #XS or #FFI C code has to be ported to Java, mind you. But @fglock has been doing just that, e.g., #DBI support via #JDBC and #JSON via fastjson2.
Boom!
The OpenLink Software #AI Layer (#OPAL) now supports AnthropicAI's #Claude language models.

Remember, query scope is SPARQL, #ODBC, or #JDBC accessible data sources.

2024 endlich noch mal auf der #JAX und werde über #Neo4j #JDBC und einen #RAG Usecase sprechen, den ich ganz cool finde…
Jep, ich bringe eine Liste mit kritischen Leseempfehlungen, nein, ich werd das ganze Zeug nicht hinter unnütz komplizierten Akronymen verstecken und ich freu mich sehr auf Diskussionen:
I wonder if people which switched away from Hibernate to straight JDBC in a Micronaut Data context saw any performance degradation.
I guess this might depend on how Hibernate was being used, but I am about to do this and evaluate performance next week.

I wrote about the new #JDBC #Driver for #Neo4j and sorry, it's on Medium… I cannot fix everything.
There's a bunch of cool stuff innit, among others the #SQL to #Cypher translation we build and the LLM based natural language to Cypher bits by @meistermeier

OK, I have maybe the most Hail Mary question ever asked but it's worth a go. My work day has been plagued by memory issues in the web servers, and the problem was that 3 different @Lob fields in the database were corrupted with the inclusion of repeated sequences of the text below.
The fields were in 3 different client accounts, in a database with no public IP and which needs an SSH key to get to. Also the Lobs were made so large (50meg or thereabouts) they caused severe performance issues. So I don't think we were hacked.
But then, what happened? The objects containing the Lobs were definitely written by our code, but those particular fields were not modified - one was in my own account, and no way was I logging in to corrupt data on a Sunday.
My best guess is that some out of memory condition caused the Lobs to be copied incorrectly? Maybe the JDBC driver got corrupted? I would add code to check for this sort of thing, but it would help if I knew where to look, so any ideas are welcome.
