Join our next meetup on June 25th! We will have 3 talks and will share some food and drinks while networking **Location:** Infrabel, Rue des Deux Gares 82, 1070 Anderlecht, Belgium **Agenda:** 17:45 : Doors open 18:00 - 18:40 : Drinks and pizza 18:40 - 18:45 : Welcome 18:45 - 19:00 : Elastic @ Infrabel 19:00 - 19:15 : Real life never-seen-before railway project 19:15 - 19:55 : From unknown and raw to real value 19:55 - 20.20 : What’s new in Elastic v9 20:15 : Wrap up **Talks:** **Elastic @ Infrabel** In this presentation, we will explain how Infrabel uses Elastic today and how it supports our current needs. We will briefly outline some future optimizations and the integration of OpenTelemetry to further strengthen and extend our Elastic platform. To showcase how we use Elastic for addressing real business use case, we will demo a never-seen-before application build in collaboration with Elastic Belgium. *Safia Souabi – Big Data Engineer at Infrabel* *Olivier-Désiré Muhimpundu – Big Data Engineer at Infrabel* **Real life never-seen-before railway project** *How Elastic helps ensure the punctuality of rail services by detecting and correlating events in real time to anticipate disruptions, ensure operational continuity and optimise the flow of rail traffic."* *Vanessa Coeurnelle – Cyber Resilience Data Analyst at Infrabel* **From unknown and raw to real value** In this talk, Chris shares how he transformed a legacy log ingestion pipeline into a structured, scalable, and insight-ready ELK-based system. Starting from loosely indexed XML/SOAP logs with minimal configuration, the project required rebuilding the data model to handle multiple message types, complex nested structures, and inconsistent field representations. Without the luxury of a full upfront redesign, Chris adopted an iterative, data-driven approach: combining exploratory analysis with dynamic mapping strategies to progressively shape the data into a usable format. He will discuss how this led to the design of flexible ingestion pipelines, including XML parsing, normalization, and generic handling of heterogeneous payloads. The talk also covers practical techniques for managing sensitive data, reducing storage overhead, and improving query performance—such as selective data retention, hashing and fingerprinting strategies, and the use of data streams. Finally, Chris will touch on how structuring the data effectively enables higher-level capabilities like anomaly detection and automated alerting. This session is aimed at practitioners dealing with messy, real-world data and looking for pragmatic ways to make Elasticsearch pipelines more robust, maintainable, and valuable. **Bios** **Christoph Evers** is a Senior Data Scientist and Data Engineer based in Brussels, with over 15 years of experience in data systems, search technologies, and analytics. He has been working with Elasticsearch since its early days, contributing to the project between 2010 and 2012 and applying it extensively as a search engine, document store, and log ingestion platform. At OpenLex, he designs and builds advanced data solutions for legal research, including full-text search engines, NLP pipelines for entity detection and anonymization, and large-scale analytics systems. His work also includes operating and optimizing ELK-based observability stacks in Linux and Docker environments. Previously, Chris held roles spanning software engineering, data science, and R&D leadership across sectors such as social media analytics, mobility and market research. His experience combines hands-on engineering with business-oriented data applications, delivering scalable systems and actionable insights for both startups and multinational clients. He mainly focuses on search relevance, data observability, and the practical use of ELK in production environments. **Olivier-Désiré Muhimpundu** is a Data Engineer at Infrabel, where he has been working for more than three years on large-scale data platforms and data projects. He holds an engineering degree from University of Mons Faculty of Engineering and a Master's degree in Artificial Intelligence. In his current role, Olivier focuses on designing, operating, and evolving enterprise data platforms based on technologies such as Apache Kafka, Elastic Stack, and Cloudera. His work spans data ingestion, real-time processing, monitoring, observability, and platform engineering in a large-scale railway environment. **Safia Souabi** is a Data Engineer with 6 years of experience at Infrabel in Brussels. With a BSc and MSc in Physics from London, she combines a strong analytical background with expertise in building and operating large-scale data platforms for mission-critical operational and asset data. Experienced with Apache Kafka, Elastic Stack, and the Cloudera ecosystem (Hadoop, Spark, Hive/Impala), she delivers scalable batch/real-time data pipelines and optimized ETL/ELT workflows. She works closely with stakeholders to translate requirements into reliable data products, with a strong focus on data quality, governance, security, performance, and platform resilience.

¡Ey, qué tal! ¿Crees que podrías sobrevivir solo con tu español? Vamos a ponerlo a prueba con un cafecito☕️ (o con lo que te dé la gana en el momento, ya sea una bebida o un snack ) Dónde: Leopold PDN. Este café puede ser algo difícil de encontrar, especialmente cuando llueve ️☔️, pero así empieza la aventura, ¿no? No esperes hasta estar completamente perdido—mándame un mensaje antes de empezar a maldecir Google Maps ️. ‼️️Si el clima se porta, picnic en el parque (Cinquantenaire), obvio 🌳🧺 La idea: Pides algo (¡obligatorio! ☝️) y te unes a la mesa. Empezamos con una mini intro y luego hablamos de todo: actividades, viajes, música… Y si tienes ganas, ¡jugamos a algo! Todo en español, así que ¡prepárate para la inmersión! Dependiendo de cuántos seamos, podemos dividirnos por niveles para que todos disfruten al máximo. Juegos: Nada de tableros gigantes que acaben tirando los cafés por toda la mesa. Solo juegos rápidos y divertidos (tipo UNO o Exploding Kittens ). Yo llevaré unos, pero si tienes alguno que te guste, tráelo sin miedo. Eso sí, los juegos con texto, ¡en español! ⏱ Horarios: Empezamos a las 15:00, pero si llegas más tarde, no pasa nada, te unes cuando quieras y te quedas el rato que quieras. ¿Vas a llegar después de las 15:30? Dímelo en el chat para guardarte un lugar. Lista de espera Si estás en la lista de espera pero realmente quieres venir, o si tienes cualquier duda, mándame un mensaje directo... Más info se puede compartir en el chat o por DM —asegúrate de revisar tus mensajes el día antes para no perderte nada crítico . ‍🐈‍⬛ El Código de los Amigos: Nada de formalidades – aquí venimos a divertirnos Respeto y buena onda – si no, ¡¿Los errores?! ¡Nos dan igual! Y si nos cuesta, cambiamos al inglés o mejor: 💃 ¿No puedes venir? Cancela para que alguien en la lista de espera pueda tomar tu lugar Si estás en la lista de espera, no te presentes sin confirmación. ¡Hasta luego!

How do we connect to people? What is so great about being different? Is love selfless? Should we be dreamers or realists? What values are we losing? When are we at our best? Does childhood ever end? Is morality a matter of convenience? What makes a person beautiful? Such questions, and many more, await you Sunday at Sister's Cafe (second floor) . After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations :-).

Dear Illinois Prairie PUG members, Thank you to everyone who attended PG DATA 2026! The conference is over, but our meetups are back, and more Postgres content is coming! Those of you who attended our May meetup are already familiar with our new (hopefully permanent) location. For others, please note that we will meet at **Chicago Innovations, 1 W. Monroe**. This time, we are trying a two-talk format. \- Zach Paden will present the talk **Declarative schema management with pgschema.** \- Anna Bailliekove will present the talk **PostGIS Quick Start** More details on talks and speakers coming soon! *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:40 - Zach. Declarative schema management with pgschema. 6:45 - 7:10 Anna: PostGIS Quick Start 7:10 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing **Speaker**: Zach Paden Zach Paden is a tech lead at Symetra with experience ranging from scrappy startups, consulting, to large regulated enterprises. His work spans data platform, analytics and application development where he’s seen more than his fair share of projects get bogged down or catch on fire due to their schema management practices. **Talk Title:** *Declarative schema management with pgschema* **Talk description** Lots of app devs struggle to understand the concept of versioning database migrations, and managing the history of these migrations can become difficult even with existing tools. Using pgschema you can write pure-sql decoratively and let pgschema derive a series of valid online migrations. **Speaker:** Anna Bailliekova Anna Bailliekova has been moving data around professionally for 15 years. Currently a staff engineer XeoMatrix, she focuses on helping organizations mature their data engineering practice, optimization problems, and geospatial data applications. **Talk title:** PostGIS Quick Start **Talk description** PostgreSQL provides rich support for geospatial computing; using transportation examples, we will take a brief tour of these features for those who want to but have been scared to try. *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. \- You will notice the change in the RSVP form\. \- We are thankful to our hosts and promise to be responsible\. \- We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). \- We do not want to waste food\, so please indicate your dietary preferences\. \- We will not close RSVPs on the morning of the meetup\, but please do your best to RSVP in advance so we can order the appropriate amount of food and drinks\. \- We want to start offering **on-site daycare**.
