**Date:** 12 March 2026 **Time:** 5:00 PM – 8:00 PM CET **Location:** [Bolt HQ](https://maps.app.goo.gl/L1wd9xND6SeM4Y1u6) Join Bolt and TiDB for an exclusive in-person meetup where we pull back the curtain on scaling massive production workloads. Discover how Bolt leverages TiDB’s distributed power to navigate hyper-growth, and get a first look at how TiDB X is redefining the category with AI-native capabilities. We’ll dive deep into real-world use cases, debate cloud architecture, and show you why the future of the database isn’t just “distributed” — it’s highly intelligent, scalable, and unified. ## What’s on the agenda? * **The AI-Native Frontier:** Get an exclusive look at TiDB X, an AI-native database platform designed to unify OLTP, OLAP, and vector data, auto-tune performance, and simplify the development of LLM-powered applications. * **The Bolt Blueprint:** Find out how Bolt utilizes TiDB in production to sustain high-velocity workloads that maintain “five-nines” of reliability. ## Is this meetup for you? If you’re building, managing, or breaking systems at scale, you belong here: * **The Builders**: Backend, platform, and infrastructure engineers looking for a next-gen data stack. * **The Architects:** Database engineers and SREs tired of manual sharding and “re-sharding” nightmares. * **The Visionaries:** Technical leaders and AI engineers ready to integrate LLMs with enterprise-grade data. * **The Optimizers:** Anyone who believes “runaway costs” shouldn’t be the price of innovation. If you’re looking to level up your infrastructure or just curious about how AI is fundamentally changing database internals, come grab a seat and join the conversation.

🙋🏻‍♂️ **Recommended:** check the group description first - it explains our approach and what we focus on You can check out the main online events [here](https://www.meetup.com/online-astrology/?eventOrigin=your_groups) ⬅️ We work **live with natal charts** and explore astrology as a **practical, living system** \- not fortune\-telling or “5\-minute answers” to "*where is my money, partner or purpose"*. This is a focused chart reading where we look at **how a person is actually structured**, where their energy flows easily - and where tension, imbalance or unused potential lives. **What we do** • balance of elements (fire, earth, air, water) - what’s dominant and what’s lacking • strong planets and key aspects - core traits, intensity, recurring patterns • active houses - life areas your energy mostly spins around • leading life scenarios - social, creative, informational, standalone, etc. Using this foundation, we explore: * how aligned a person already is with their chart * where inner conflicts and shadows are located * how to translate chart insight into **real-life action**, so the chart starts unfolding on a higher octave. **How this differs from "interpretative astrology"** We don’t read *planets in signs, one by one* to draw a set of disconnected descriptions. That approach often creates more confusion the deeper you go. Here, the chart is treated as **one coherent organism** \- with structure\, hierarchy and internal logic\. **The format** • meet and greet • live chart reading & discussion • friendly, respectful atmosphere • open both to beginners and astrologers - questions and observations are welcome **How to prepare** Please send your **date, time and place of birth** in advance so I can prepare the chart. Come with real-life questions, for example: • What helps me restore energy? • Where do I lose focus or motivation? • What environments support me best? Come curious - leave with insight. 🏠Place: Reval Cafe Müürivahe.

To all locals, expats, and visitors in Tallinn, welcome! My wife and I are delighted to invite you to study the Word of God with us every Friday at 5:30 p.m. in a casual setting, accompanied by coffee and tea. We believe the Bible is entirely true, and we strive to live by its teachings. We also believe that the love of God is so powerful that it can touch hearts and heal what's broken in all of us. Let's study Christianity together to help you find answers to questions like: * What is the meaning of life? * How do I deal with difficult situations? * Who is God, and what is the Trinity? * How can Jesus Christ help me? * How can I forgive and treat others with love? Please join us or reach out if you have any questions! The meetups are in English.

**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 **Abstract** TBD **YouTube Link** TBA

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.
