Not having transactions didn't mean you couldn't implement a lock!
This is how we implement a lock mechanism in Elasticsearch inside Kestra.

At Kestra, the workflow orchestration and scheduling platform I work for, we have two repository implementations: JDBC (with support for H2, MySQL, and Postgres) and Elasticsearch. In JDBC, locking a record for processing is fairly easy: 1. SELECT FOR UPDATE ... WHERE ... will place a lock on the record(s) 2. We process the record(s)

TIL that you can create indices concurrently in Postgres using `CREATE INDEX CONCURRENTLY ` and in MySQL by using `, ALGORITHM=INPLACE, LOCK=NONE`.

Les vidéos de Cloud Nord 2025 sont en ligne 🎉
Notre monteur fou (moi 😭) a fini d'uploader toutes les vidéos captées le 23 octobre dernier.
C'est pas parfait, mais c'est pas si mal pour du contenu enregistré depuis un coin de table 😅
Tout est sur Youtube : https://www.youtube.com/playlist?list=PLVQhat0Bx0WB-fhbbQ0bQkhfTLAZIU2IU
"Post-Quantum Hybrid Key Exchange for TLS 1.3" is now a JEP Candidate! This feature will protect Java applications using TLS and the javax.net.ssl APIs from future quantum computing attacks.
After a few small contributions to Langchain4J, I finally made my first substantial contribution: a Docker MCP transport, which allows for securely running an MCP server inside an isolated container without relying on an external process.
