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.

Join us on Sunday, June 28th, for our weekly morning run to get your day started on the right foot! We are gathering at our regular haunt, Café Belga, and we can't wait to see you there—whether you're a first-timer with the Brussels Runners Meetup or a familiar face. What to Expect: Distance: \~13 km Pace: \~6 min/km Mixed Terrain: A great combination of dirt paths, forest trails, and some road sections. Scenic Views: Enjoy the local beauty as we traverse diverse landscapes starting right from Place Flagey. Good Company: Run with like-minded individuals and make new friends. Post-Run Coffee: We'll wrap things up right where we started for an optional gathering, refreshments, and camaraderie at Café Belga. Bag drop : No See you all on June 28th outside Belga! Let's hit the trails.

We will follow the GR 126 from Lustin to Namur, a route along the Meuse Valley, packed with steep forested climbs, stunning river viewpoints, and a historical finish passing Namur's Citadel - and maybe a stop for a drink or ice-cream, depending on the train schedule. There is rain forecasted for the afternoon, but that should not stop us from hiking :) The number of participants is limited to 15, so please manage your registration responsibly: only sign up if you really intend to come and cancel as soon as you know you can’t (this also goes for people on the waiting list!). We will try to keep close to an average moving speed of 5km/h. We will walk both on paved and unpaved roads. I’ve not tested this track beforehand, so it’s possible that there are some mistakes in the planning (i.e. it may become longer ;-). ●●You can find the gpx track here: https://loc.wiki/t/270911426?wa=sc ●●Meeting point: We meet at 8.10 in Brussels Central station next to the main stairs. Our train (IC 2108 to Luxembourg) leaves from platform 3 at 08.20. We have a connecting train in Namur and arrive to Lustin at 10.05. ●● Trains back to Brussels: direct trains from Namur are every hour at XX.16. ●● Train ticket: One way ticket to Lustin is 9.60€ or 5.80€ with train+. One way ticket from Namur is 8.00€ or 4.80€ with train+. Return ticket to Lustin should also be ok. ●● Specifics: Distance: ± 22 km Elevation gain: 400 m Net walking time: ± 5 h Weather forecast: sunny and hot, with some rain forecasted in the afternoon. In the unlikely case of too bad weather, I may cancel a hike, even few hours before the event. If this must happen, I will of course update the Meetup website and send out an email to those registered. So it is important to have access to either the Meetup website and/or your emails. ●● What to bring: * Plenty of water for the heat + pack your own lunch/snacks * Comfortable hiking shoes and clothes * Sun and bug protection (Sunscreen, hat, tick repellent, etc) * Raingear * Small money for drinks/ice-cream ●● Basic rules: Please RSVP only if you really intend to come. And if your plans change, update your RSVP asap, even hours before the walk. This is basic courtesy towards others. Repeated late cancellations are not well considered (at all). No-shows are even worse. Do not show up for a hike unless you are on the “going” list. ●● Acknowledgement of member responsibility and release of liability: You are responsible for yourself and should be fit enough if you want to take part. As the participation in the events is strictly voluntary and you freely choose to join, it is the responsibility of individuals participating to ensure that they are fit enough and have adequate coverage to protect themselves. By signing up for this event, you agree to release the organisers from any responsibility and liability.

We do cycles of 4-6 weeks, with a progressive intensity, and the last session is lighter. Program: 15’ warm up **To be defined** Cool down to get back to the starting point… or more S=All out sprint RF = Run fast, at MAS (Maximum aerobic speed) CF = Run comfortably fast (1h threshold) J = Jog, recuperation Notes: It should take about one hour in total, as the cool down will end when we reach back to the meeting point. It's NOT required to have an activity tracker or smart watch to be able to follow the program, as I'll be giving signals with a whistle. For the "run" part, you can follow your own pace and we'll be regrouping in the "jog" part. Intervals training is not advised for total beginners. To have an idea, the average pace at the warm up is around 5'45"/km-6'/km so this pace should feel very comfortable ***Acknowledgement of member responsibility and release of liability.*** By signing up for this event, you agree to release the organizers from any responsibility and liability in all claims. As the participation is strictly voluntary and you freely choose to join, it is the responsibility of individuals participating to ensure that they are fit enough and have adequate coverage to protect themselves.

Hi everyone. Boulder session at Arkose. They have airco to help with the heatwave.
