AI-Powered Data Analytics Innovation with Vectors, Graphs and Intent
Ready to scale your RAG, AI workloads, and search? Join us Thursday 5th March 2026 on AWS TLV Floor 28 for a content-packed session in collaboration with AWS about using OpenSearch for AI-Powered Data Analytics and modern search methods: Semantic Search, S3 Vectors and GraphRAG.
Please register here: https://aws-experience.com/emea/tel-aviv/event/0c9fcbcd-8629-4e99-b4b0-fbca41b978c4
\* How to go beyond Keyword Search with OpenSearch
\* Modernizing Retrieval with Semantic Search and Query Intent Understanding
\* Hybrid search and Agentic RAG
\* Knowledge Graphs, GraphRAG, and Neuro-Symbolic AI
\* Structured intelligence for GenAI
\* Amazon S3 Vectors for vector search at billion scale
Agenda:
**Beyond Keyword Search - Modernize Retrieval with Semantic Search and Beyond with OpenSearch,** Itamar Syn-Hershko, BigData Boutique
Explore how semantic search transforms information retrieval by understanding meaning and context rather than just matching keywords. Learn how OpenSearch's vector engine enables sub-second semantic search across billions of vectors combined with text-search, powering intelligent applications from recommendation engines to conversational search experiences. We'll also discuss sparse vs dense vector embeddings, using LLMs to derive and leverage query intent, and more.
**Unlocking Structured Intelligence for Generative AI with Knowledge Graphs, GraphRAG and Neuro-Symbolic AI,** Baruch Assif Osoveskiy, AWS
Discover how knowledge graphs enhance Retrieval Augmented Generation (RAG) by providing structured, interconnected information for more accurate and explainable AI responses. Learn how GraphRAG combines the power of graph databases with large language models to deliver contextually rich, grounded answers.
**OpenSearch + Amazon S3 Vectors - Cost-Optimized AI-Ready Storage,** Roi Gamliel, AWS
Learn how Amazon S3 Vectors introduces native vector support at cloud scale, reducing storage and query costs by up to 90% compared to traditional vector databases. Discover how to store billions of vectors with sub-second query performance while leveraging S3's industry-leading durability and scalability.

Columbus Code & Coffee 84 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
**What to Expect at the Intro Circle**
\~\~\~\~\~\~\~\~\~\~\~\~\~
Near the beginning of the event (1:30 pm), we do a standup:
* Organizer announcements, updates, and logistics
Round 1 - (7 secs max):
* Your name
* What you're working on
* What you can help others with
Round 2:
* Community events you wanna plug. If none, that's cool too.
Round 3:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
DoJo (Informal Python Meeting)
**New Dojo Location!**
**Draft Day Columbus**
1130 Dublin Road
Columbus, OH 43215
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

CBusData - Discover the Power of Window Functions
Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems:
* Using running totals
* Performing operations in intervals
* Identifying data gaps and islands
* Performing aggregates without losing detail
Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
Prototype, Play, and Build Workshops (In-Person @GameArena)!!!
This month, we are in-person at GameArena!!! We will also be joined by students and their games from [Shawnee State](https://www.shawnee.edu/game-design-programs)!
\-\-\-
Join us for our our monthly COGG Prototype and Play event @GameArena! Come to play and showcase your games.
We're back in the upper levels of the catwalk mezzanine area. It'll be packed with lots of camaraderie playing your game(s) and other's games on the 2nd floor as well as the 1st floor in the gaming room below the mezzanine.
Light snacks and water provided but you can buy food and drinks at the bar (alcoholic drink ID required).
[https://www.game-arena.co/menu](https://www.game-arena.co/menu)
**Attendees:**
Don't have a game to show? Not a problem! All are welcomed and invited from all ages and backgrounds. The more we can have to play test our games the better!
**Developers:**
Do you have a game that you would like to get critical feedback on? Would you like an excuse to work on a game with other talented artists, programmers, musicians, designers, and writers? Digital, table-top, non-experienced developers, and the like are welcomed! We'll provide signage for your game to help others learn more about your work. Wifi, outlets, tables, and seats (though standing tables also) are available.
Come to the Prototype and Play workshop to collaborate and meet local game developers for an evening of epic and raw game play fun! Play works-in-progress, show off your own game, work with others to add polish to a game, or even lend your talents to other fellow developers.
Can use South Garage at the Gateway with a $5 voucher on your way out.
