In this session, Alexey will take a deep dive into how large language models are trained, fine-tuned, and served, with a focus on the data pipelines and architectures that make it all work. You’ll see live demos of ClickHouse tackling massive AI-scale datasets in real time, along with performance benchmarks that reveal just how far you can push the engine.

In 2021, Alexey came together with two co-founders to build ClickHouse and is focused daily on expanding its capabilities and optimizing performance. His expertise lies in data processing algorithms and high-performance technologies, driving his passion for data and innovation in the field. Ask him about speed, or CI, go on... we dare you! **🎤 Session Details: Speed as a Feature: Markethac's Journey from BigQuery to ClickHouse** Every e-commerce insight starts with a question — but when your data grows faster than your queries can run, the answers stop coming in time. In this session, Adhitya will walk through how Markethac migrated its analytics stack from BigQuery to ClickHouse to meet the real-time demands of Indonesian e-commerce intelligence at scale. You'll get a behind-the-scenes look at the architecture decisions, ingestion pipeline design, and optimizations that made the migration work — along with live demo showing the performance gap between the two engines on real marketplace data. If you're sitting on a growing analytical workload and wondering whether your current warehouse can keep up — this one's for you. **Speaker: Adhitya Cahyadi, Business Director @ Markethac** Adhitya Cahyadi is the Business Director and Chief of Product at Markethac, an e-commerce intelligence platform built for the Indonesian and Southeast Asian market.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. 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 sponsored the Dianetics & Scientology Self-Improvement Center.
