Singapore User Group - April 16 2026
2026-04-16 18:30 - 20:30 (America/Los_Angeles)
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!
7:00 PM – 8:00 PM — What’s New, What’s Next: OpenSearch Community Meetup
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.

Retrieve. Remember. Reason - with Women of Search - Berlin - June 9 2026
2026-06-09 18:00 - 21:30 (Europe/Berlin)
An evening of search, memory & agents – brought to you by Women of Search at Berlin Buzzwords
About the Event
​Berlin Buzzwords week is our favourite time of year – and this year, we’re making it count.
​Women of Search is bringing together the community for an evening of sharp talks, honest conversations, and great company – right in the heart of Berlin (Thank you Haystack!).
​The theme? Retrieve. Remember. Reason. – three verbs that map neatly onto where our field is right now: from search and retrieval, to memory and context, to agents that actually reason and act.
​We’re thrilled to be joined by three brilliant partner communities shaping this space:
​🔍 OpenSearch – on the retrieval layer that makes everything else possible
🧠 Cognee – on memory, knowledge graphs, and what AI systems need to remember
🌾 Haystack – on orchestration, agents, and putting it all together in production
​Three short talks. Real practitioners. No fluff.
​Followed by networking, drinks, and the kind of conversations that don’t happen in conference halls.
​Who is this for?
​Women of Search started as a community for women in search – and we’re evolving. If you work in search, AI, agents, retrieval, NLP, or anything in between, this evening is for you. Women and allies warmly welcome.
