**[Christoph Eder](https://www.linkedin.com/in/christoph-eder-0ab776194/)**, Senior IT Consultant at **[EBCONT](https://www.ebcont.com/en)**
**Abstract:** In this talk, we'll show how we developed a flexible enterprise search solution using Elasticsearch — one that not only works in the cloud and with LLMs, but can also run on-premises and be easily combined with different LLMs.

19:00 **Talk #2 Effortless Innovation: Serverless & Stateless with Elastic** **[Matthias Holzgethan](https://www.linkedin.com/in/matthias-holzgethan/)**, Principal Solutions Architect at **Elastic**
**Abstract**: Experience the next evolution of Elastic: a stateless architecture that decouples compute from storage, leveraging blob stores like S3 for seamless persistence. We will show how Elastic’s new design enables dynamic scaling, smart defaults, and a streamlined developer experience—empowering you to run blazing-fast queries on cold storage. We will discuss how Elasticsearch was reimagined for the cloud era and you will see how you can get started with these powerful capabilities today.

19:30 **Networking - Open discussions, Drinks, Snacks**

Invite your friends and RSVP on this page.

We hope to see you there!

**Address:** Recorded Future's office, Hvitfeldtsplatsen 7, 411 20 Göteborg

**Agenda:**
17.30 Doors open, food, networking and drinks
18.00 Building large scale semantic retrieval with Elasticsearch
18.30 Upgrading huge Elasticsearch clusters without downtime

19:45 Networking
20:30 Meetup ends, we will be moving on to a nearby pub to continue the conversations. We encourage all participants to join!

**Talks:**
**Building large scale semantic retrieval with Elasticsearch**
Over the past two years, we at Meltwater have built MIRA, our new insight chat based GenAI agent. The search and retrieval part of MIRA is implemented by a combination of our existing petabyte sized Elasticsearch cluster as well as a brand new, 10s of billions scale 'vector search cluster' powered by Elasticsearch. In this session, we’ll walk through the architecture, the benchmarks and tests that we made, the problems we hit, and the lessons we learned along the way.

*Speakers:* *Sture Svensson and Karl Neyvaldt from Meltwater*

**Upgrading huge Elasticsearch clusters without downtime**
The talk covers our Elasticsearch 7.x to 8.x upgrade journey, key challenges like performance issues from frequent document updates, and lessons learned from upgrading large clusters. Mitigations, code rewrites, timeline, and operational tweaks that ensured data safety and a smooth upgrade.

*Speakers:* *Max Gabrielsson (Lead Software Engineer) and Oskar Montin (Infrastructure Architect ) from Recorded Future*

**Improve your search with intent and improve relevance**
Engage your users and improve the search experience of your application. Provide answers that matter and improve conversion based on the expressed intent in a search query.

*Speaker:* *Peter Steenbergen (GenAI Specialist) from Elastic*

*A big thank you to the host for this evening, Recorded Future!*

In this talk, we’ll cover the capabilities introduced since then that make Elasticsearch (and the rest of the Elastic Stack) a strong choice for going beyond log analysis and classic BM25 search. Topics include dense vectors, sparse vectors, and hybrid search, along with features that improve effectiveness in modern retrieval scenarios.
