Talk 1: Large Language Models and their role within the current Search & AI ecosystem
Speaker: Afonso Mendes
Talk Summary: This session looks beyond the buzz to question what large language models (LLMs) truly bring to the table, and where their limits lie. We will examine how these models fit within the broader ecosystem of Search and AI tools and how they relate with more traditional systems. From uncovering where LLMs shine to exposing where they do not, the discussion invites a clearer view of their real value in today’s landscape.
Other talks to be submitted soon! If you’d like to join and present at this meet-up, please get in touch with Bernardo or Carlos!

Hacking the Stack: Using OpenSearch Dashboards as an Application Framework
Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of an enterprise-grade risk, compliance, and security platform built entirely on top of OSD. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience.
Join us for a deep dive into the engineering reality of the OpenSearch stack, including:

The Analysis: Why the OpenSearch stack beat out the competition.
The Build, Beyond Visualization: How to implement custom React components to build complex workflows and interactive UIs within OSD.
The Integrations: Integrating Wazuh for agent management and ingesting data at scale.
The “Gotchas”: Honest, real-world lessons on data handling, state management, and what to look out for.

If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!

Hi OpenSearch Community in Singapore,
This is our first networking event for OpenSearch enthusiasts and builders in Singapore. OpenSearch is evolving rapidly, and we’re witnessing significant shifts in how the project approaches everything from AI integration to everyday log management.
Agenda

6:30 PM – 7:00 PM — Networking and Meet & Greet with some Pizzas!

Speakers – Michael Supangkat and Farid Baharuddin

What We’ll Cover
We’ll open with highlights from the OpenSearch 3.5 release — features you can start using today. These include the Prometheus Discover experience, which enables you to visualize metric data from Prometheus data sources directly alongside your logs and traces, as well as new support for agentic conversation memory, making it significantly easier to manage context and history for LLM-powered applications.
We’ll then take a broader look at the 2026 vision, exploring planned features that signal where the project is headed:

Automated Query Insights — How the engine is moving toward self-healing capabilities by automatically detecting slow query patterns and recommending optimizations.
Interleaved A/B Testing — A closer look at tuning search relevance using live data directly within the engine, eliminating the need for external tooling.

Looking forward to seeing you and learning from each other!

Milan User Group - May 27 2026
2026-05-27 18:30 - 20:30 (Europe/Rome)
Ti è mai capitato di avere tutto sotto controllo… e comunque non capire cosa stava succedendo?
Benvenuto nel mondo moderno: microservizi, eventi, pipeline, e una valanga di dati che promettono chiarezza.
Spoiler: non basta.
Search, observability e open source condividono lo stesso obiettivo: trasformare dati grezzi in qualcosa che abbia senso, e il farlo mentre il sistema cambia, scala, e a volte …si rompe.
Non è (solo) una questione di tool. È capire come leggere, collegare e interpretare quello che abbiamo davanti.
Da qui partiamo.

Have you ever had everything under control… and still not understood what was happening?
Welcome to the modern world: microservices, events, pipelines, and an avalanche of data that promises clarity.
Spoiler: it’s not enough.
Search, observability, and open source share the same goal: transforming raw data into something that makes sense, and doing so while the system changes, scales, and sometimes… breaks.
It’s not (just) a question of tools. It’s understanding how to read, connect, and interpret what we have in front of us.
Let’s start from here.
