Hadoop

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.

We will share further details as soon as a new date is confirmed. Thank you for your understanding. **"We all agreed"... did we, though? Or did we just stop arguing?** This month we open the facilitator's toolbox and test, hands-on, several techniques for building real consensus: prioritizing, gauging support with Kaner's Gradients of Agreement, getting to the true source of disagreement. You won't watch a presentation - you'll be part of the group, we'll test the tools together and reflect on what kind of situations they are best used. Come ready to disagree productively. Led by [Sylvain Vezolles](https://www.linkedin.com/in/sylvainvezolles34d13d93d/), who brings his passion for theater to this interactive workshop, participants will be challenged to rethink how they connect, listen, adapt, and influence.

Hi everyone, This coffee morning event is @MIR Concept Coffee Store! Saturday, 27 June 2026, from 10:00 - 13:00. MIR opened its doors 4 years ago, right off Place Jourdan. Doriana, the owner, is a super nice host, and is excited to have our group as her café. The café is very beautiful and has great coffee, and many yummy food options. Their Instagram channel: https://www.instagram.com/mirconceptstore/ **The address is:** MIR Concept Coffee Store Rue Gray 4A 1040 Etterbeek *** 1. The **prime time** of the event is **10:30 - 12:30**. That's when most people will be there. 2. When you enter the gallery, it's either on the right-hand side or left-hand side of its hallway, depending which entrance you take. 3. If you intend **to join past 12:00** (high noon), then there is no need to register. Just come and join! 4. **DON'T forget to cancel** if you can't join! 5. **Please, be respectful towards each other during the event. (And after ;))** **As always, feel free to follow us on INSTAGRAM!** [https://instagram.com/weekendmorningcoffee?igshid=OGQ5ZDc2ODk2ZA==](https://instagram.com/weekendmorningcoffee?igshid=OGQ5ZDc2ODk2ZA==) **THE STRUCTURE of THE EVENT:** * I will post the event on Saturday/Sunday evening for the following Saturday. * I send out a reminder to everyone on Friday. * There is sometimes a waiting list. * In case RSVP is closed (once there are 10-15 people on the waiting list), I might reopen it on Friday, depending on the number of cancellations in the meantime. * **For everyone on the waiting,** please check your status and messages on Friday evening the latest. I message everyone on the waiting list on Friday. * **Please, move to "not going" AS SOON AS you know that you can't come anymore, that includes everyone who is on the waiting list.** **IMPORTANT:** * **Please, be respectful towards each other during the event. (And after ;))** * When you register yourself, be careful not to register accidentally a +1 guest (unless you bring a guest). It happens very often. * If you have any questions then, message me. *** **A MESSAGE FOR NEWCOMERS:** *In the three years of hosting this coffee group, I have met many people who struggle with anxieties when coming to an event for the first time. Sometimes, it took them more than one attempt before being able to join.* *Occasionally, people reach out to me before the event, and I have always been grateful for that as it offers the opportunity to communicate with each other and to find the best and most gentle way for that person to join the group.* *I would like to encourage everyone who struggles with this to contact me before. It would really be too bad if you can't join us, as it mostly gets better the second or third time you come.* *In addition to that, if you arrive and notice any signs of nervousness or fear, you can always let me know right then.* **THANK YOU AND SEE YOU ALL ON Saturday!**

Let's meet to write ! Schedule : 11:00 - 11:30 am : Presentation tour. Share briefly with the group about your project and your "goal of the day". 11:30 - 13:30 : Let's write ! 13:30 : Conclusion tour. Did you achieve your goal of the day ? See you soon !

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.
