**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.

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.

🙋🏻‍♂️ **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.

We’re going to have a nice outside full-body workout, 🏋🏻‍♀️ controlled by a fitness coach Yuliia, who is also a World Grappling Silver Medalist (martial arts), so take a good mood and wear the sports clothes!

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.

You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches!

Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life. Mission: grow, support, and provide community for atheists in Central Ohio. Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
