Hosted By
JG Meillaud, Community Leader
Hello,
I’m an independent Atlassian consultant working full-time for France Télévisions (French public broadcast organisation). I love running this little in-house Jira shop.
I’ve been managing projects and implementing collaboration tools since in 2012 and the Atlassian products and events have been instrumental in my career.
I think the job has evolved a lot in this time, from implementing pretty much anything following exotic requirements, to the art of challenging needs and crafting smart and simple solutions while continuously cleaning up our mistakes of the past! Feel free to reach out if you want to chat about that :)
Outside of work, I’m quite outdoorsy, I love hiking, sailing and rock climbing, but also quite into board games.

🚀 **In this session:**
* What *Agentic AI* really is (and how it differs from LLMs)
* How LLMs work under the hood (tokens, embeddings, context)
* When to use fine-tuning, RAG, or prompt engineering
* How MCP connects AI to your data, APIs, and lakehouse
* Key benefits, risks, and real-world considerations
Cut through the hype and understand how AI actually works - and how to use it.
**Next up: Gilles Philippart**
Software Practice Lead at Confluent, Gilles will explore how **Iceberg, Kafka, Flink, and Tableflow** come together—and what that means in the world of AI.
Expect a practical perspective on building scalable, real-time data architectures that power modern AI use cases.

Meetup PostgreSQL Paris -
Au programme :
* "UUID dans PostgreSQL" par [Sebastien Delobel](https://www.linkedin.com/in/sebastiendelobel/)
Dans un monde ou l'uuid devient la norme, nous allons voir ce que l'on peut faire avec cette nouvelle version de l'uuid.
* "Utiliser un opérateur k8S pour PostgreSQL (Cloudnative-pg) et migrer 300 de nos instances de production" par [Thomas Boussekey](https://www.linkedin.com/in/thomasboussekey/)
Mirakl est une licorne e-commerce française proposant des solutions SAAS autour des marketplaces depuis 2012. PostgreSQL et les solutions cloud sont parmi les piliers de notre infrastructure technique.
Il y a quelques mois\, nous avons décidé de challenger notre infrastructure technique en hébergeant PostgreSQL sur des machines virtuelles cloud\. Cela nous a conduit à migrer notre base de données vers Kubernetes en utilisant un opérateur PostgreSQL\. Nous avons opté pour \[cloudnative\-pg\]\(https://cloudnative\-pg\.io/\) \(un projet open source incubé par la CNCF\)\.
Dans cette présentation, je présenterai succinctement l'infrastructure précédente et l'opérateur cloudnative-pg. Nous exposerons ensuite les principales caractéristiques de cet opérateur. La présentation se conclura par une description du processus de migration de l'ancienne stack, puis l'upgrade de version majeure de Pg12 à Pg17.
Par contrainte de **sécurité**, merci de vous inscrire avec vos **noms**, **prénoms et entreprise**, et de le faire avant la date limite.
Merci à L'atelier de nous accueillir
Rejoignez-nous lors de notre prochaine rencontre du groupe d'utilisateurs PostgreSQL à Paris pour un atelier sur la maîtrise du développement SQL avec PostgreSQL. Que vous soyez débutant ou expert en gestion de bases de données, cet événement est parfait pour tous ceux qui cherchent à améliorer leurs compétences en développement et en optimisation de bases de données. Notre conférencier expérimenté couvrira des sujets allant des bases de données aux techniques SQL avancées, tous axés sur PostgreSQL.
Ce meetup proposera des clés pratiques pour vous aider à approfondir le développement d'une base de données à l'aide de PostgreSQL. Ne manquez pas cette opportunité de réseauter avec des personnes partageant les mêmes idées, de partager vos connaissances et d'apprendre de précieuses informations auprès d'experts dans le domaine. Que vous travailliez sur vos propres projets ou que vous souhaitiez simplement développer vos compétences en bases de données, cet événement vous fournira les outils et les connaissances dont vous avez besoin pour réussir. Rejoignez-nous pour une soirée d'apprentissage, de collaboration et de plaisir lors de la rencontre du groupe d'utilisateurs PostgreSQL à Paris.
Meetup ElasticFR #103 - La Home Sweet Company
🎤 Envie de proposer un sujet pour un prochain évènement ? N'hésite pas à venir en parler sur https://ela.st/cfp-elasticfr. 🙏🏼
**Agenda**
* Ouverture des portes
* Update sur Elastic (5 minutes)
* Talk1: La carcasse et sous le capot : Agent Building sans filtre par Aziz Imgharne (20 minutes)
* Talk2: Tri contextuel et haute cardinalité : l'approche par sparse vectors avec Elasticsearch par François Gaillard (20 minutes)
* Talk3: Sécuriser les migrations Elasticsearch : alias swap, rollback et reindex sans perte de données par Said Bouigherdaine (10 minutes)
* Food & drinks
**La carcasse et sous le capot : Agent Building sans filtre**
*Par Aziz Imgharne, EAfterWork*
On décortique comment construire des agents IA Prod Ready et quand basculer vers des agents spécialisés. On finit par l’essentiel pour la prod : observabilité, tests, évals et fiabilité.
**Tri contextuel et haute cardinalité : l'approche par sparse vectors avec Elasticsearch**
*Par François Gaillard, ADEO*
Dans l'e-commerce à grande échelle, le tri contextuel traditionnel est un véritable défi en termes de performance. Chez ADEO, nous gérons le catalogue Leroy Merlin qui compte plus de 5 millions de produits et plus de 700 000 contextes de requête. Les solutions classiques (qui induisent une mapping explosion ou des nested objects) ne permettaient tout simplement pas de passer à l’échelle.
Les approches de ranking à deux étages écartent souvent des produits performants lors de la phase de retrieval (sélection large), avant même qu'ils n'atteignent le moteur de tri. Il nous fallait intégrer ces signaux contextuels dès la première étape.
Au cours de cette présentation, nous montrerons comment nous avons traité chaque contexte de requête comme une dimension unique au sein d’un sparse_vector Elasticsearch. En utilisant un vecteur de requête avec une unique composante non nulle, le produit scalaire se transforme en une simple lecture de données (feature lookup) ultra-rapide. Nous avons ainsi transformé une opération de similarité complexe en une extraction de score simple et performante.
Nous partagerons nos résultats (obtenus sur un catalogue d'un million de produits) ainsi que les compromis identifiés.
**Sécuriser les migrations Elasticsearch : alias swap, rollback et reindex sans perte de données**
*Par Said Bouigherdaine, LexisNexis*
Toute équipe qui fait tourner Elasticsearch en production finit tôt ou tard par se heurter au même problème : un changement de mapping est appliqué, la réindexation échoue en cours de route, et le cluster se retrouve bloqué dans un état à moitié migré que personne ne sait comment rattraper.
Les bases SQL ont Flyway. Les clusters de recherche, eux, se débrouillent avec des scripts curl et des messages Slack.
Cette présentation détaille les patterns qui permettent de sécuriser les migrations de schéma Elasticsearch en production — migrations versionnées, bascule d’alias avec retour arrière, pièges de la réindexation asynchrone, verrous distribués — le tout illustré avec le CLI open-source [ScaledSearch](https://github.com/saidbouig/scaledsearch).

Columbus Arduino Raspberry Pi Enthusiasts (CARPE) (Check Location)
Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration!
This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired.
**New to electronics or curious about tinkering?**
You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building.
While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**Abstract**
*Customize the IDE: Building Extensions for Visual Studio Code*
Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs.
In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling.
The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options.

Columbus Code & Coffee 87 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
