Hadoop

Dear Community, Another month with two great talks in the agenda. This time we are meeting at our home **NLND Berlin**, with one talk covering AWS AgentCore while the second one about Redshift Data sharing. =================================================== 18:30 - Warming up and networking chat 18:45 - Intro by AWS UG Berlin & NLND 19:00 - 19:40 - **Gamei Chin & Milad Rezaeighale // The Diabetes Sweet Spot: Using AWS AgentCore to Empower Data-driven Lifestyle Decisions** This session is about building production-ready agentic workflows with Amazon Bedrock AgentCore—from running agents securely at scale on a managed Runtime, to exposing and orchestrating tools via AgentCore Gateway (including MCP-based tooling), adding different types of memory for context and personalization, and enforcing security and governance with Identity and Policy for controlled tool access. It ends with a live demo of a practical use case: an agentic app for glucose monitoring, showing the end-to-end workflow and monitoring in action. 19:40 - 20:00 - Networking break with food, snacks and drinks 20:00 - 20:40 - **Jirka Hubacek // Breaking Down Monolithic Redshift Using Data Shares** As data platforms scale, managing competing workloads in Amazon Redshift becomes increasingly challenging. Traditional WLM (Workload Management) often isn’t enough to effectively prioritize traffic — you end up facing a classic “chicken and egg” problem: should ETL pipelines or client-facing queries get priority? With the introduction of Redshift Data Sharing, there’s now a more flexible approach — you can create multiple Redshift instances that consume data from a shared source, isolating workloads without duplicating storage. 20:40 - 20:45 - Closing & Final Remarks =================================================== **Very Important: There is no "waitlist" for our regular sessions.** However, there are limited seats available. If you want to make sure you can attend: Register yourself with your "full name" here at meetup.com Arrive on time - seats are first come, first serve. As soon as there are seats available, you are welcome to join with your registration.

**KI x Nachhaltigkeit: Wer baut mit?** **Arbeitstreffen in Berlin** Ich organisiere ein kleines, fokussiertes Treffen für Menschen, die sich bereits intensiver mit KI im Nachhaltigkeitsmanagement in Unternehmen beschäftigen und Interesse haben, daraus konkrete Anwendungen gemeinsam weiterzuentwickeln. Nach einem kurzen Kennenlernen schauen wir auf konkrete Anwendungsfälle aus der Praxis und diskutieren, ob und in welcher Form Zusammenarbeit sinnvoll sein kann. Eine Moderatorin begleitet den Austausch. **Für wen?** Für Menschen mit praktischer Erfahrung an der Schnittstelle von KI und Nachhaltigkeitsmanagement in Unternehmen — zum Beispiel in Nachhaltigkeitsmanagement, Beratung, Datenarbeit, Automatisierung oder Tool- bzw. Produktentwicklung — und mit Interesse daran, Dinge gemeinsam umzusetzen. Bringt gern einen konkreten Use Case, eine Fragestellung oder eine Idee aus eurer Praxis mit. *** **English** **AI x Sustainability: Who Wants to Build Together?** **Working Session in Berlin** I’m organizing a small, focused gathering for people who are already working more deeply at the intersection of AI and corporate sustainability management and are interested in developing concrete applications together. After a short introduction, we’ll look at practical use cases and discuss whether, and in what form, collaboration could make sense. The session will be supported by a moderator. **Who is this for?** For people with practical experience at the intersection of AI and corporate sustainability management — for example in sustainability management, consulting, data work, automation, or tool or product development — and an interest in building things together. Feel free to bring a concrete use case, question, or idea from your own practice.

Estuarine Mapping ist ein mächtiges Werkzeug aus dem Cynefin-Ökosystem, um strategische Entscheidungen in komplexen Umfeldern zu navigieren – aber wie sieht das konkret aus, wenn man es zum ersten Mal in einer Organisation einsetzt? Wir haben Estuarine Mapping selbst durchgeführt und dabei wertvolle Einblicke gewonnen: Was hat gut funktioniert? Wo sind wir an unsere Grenzen gestoßen? Und welche Fragen haben sich erst im Prozess aufgetan? Beim diesem Meetup teilen wir unsere Erfahrungen aus der Praxis – ungeschönt und ehrlich. Kein perfekter Case Study, sondern ein offener ACHTUNG: Anmeldung über das [Meetup der CyCoBe](https://www.meetup.com/cynefin-community-berlin/events/313817652/?utm_medium=referral&utm_campaign=share-btn_savedevents_share_modal&utm_source=link&utm_version=v2&member_id=206720451) Austausch über das, was wir gelernt haben und was uns noch beschäftigt. Was dich erwartet: * Ein kurzer Einblick in unsere Estuarine-Mapping-Session und den Kontext * Konkrete Learnings und Herausforderungen, die wir mitgenommen haben * Offene Diskussion: Wie geht ihr mit ähnlichen Situationen um? * Raum für Fragen, Ideen und gemeinsames Weiterdenken Ob du Estuarine Mapping bereits kennst oder erst neugierig geworden bist – komm vorbei.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
