Fan Fiction

As real-time systems become the backbone of modern products, the way we design and operate data infrastructure is evolving fast. In this meetup, we’re bringing together experts from Riskified, Confluent, and Wix to show how Apache Flink and Apache Kafka power the next generation of streaming architectures—from resilient, fault-tolerant pipelines and reusable data products to AI-driven decisioning at massive scale. Whether you’re a data engineer, platform builder, or AI-curious developer, this evening will give you practical patterns and fresh ways to think about real-time systems. **Agenda:** 18:00 - 18:30 - Mingling, drinks, and snacks 18:30 - 19:00 - Supercharge Your FlinkSQL Job: Use a Hybrid API Approach to Achieve Perfection - Gal Krispel, Senior Data Platform Engineer at Riskified 19:00 - 19:30 - From Data Mess to Data Products: Unlocking Real‑Time Value with Data Streaming - Ohad Israeli, Senior Solutions Engineer Team Leader at Confluent 19:30 - 20:15 - AI vs. Karen: Building Real-Time Sentiment Analysis Pipelines at Scale - Josef Goldstein, Head of R&D, Big Data Platform at Wix.com 20:15 - More drinks and mingling The talks will be delivered in Hebrew. \-\-\-\-\-\-\-\-\-\-\-\- **// Supercharge Your FlinkSQL Job: Use a Hybrid API Approach to Achieve Perfection - Gal Krispel, Senior Data Platform Engineer at Riskified** Apache Flink’s SQL interface almost sounds like a dream: write standard SQL - get a full-blown streaming app. However, dreams and reality rarely align, and FlinkSQL achieved a questionable level of production readiness. In this session, we’ll explore the known upsides and downsides of FlinkSQL. From the enormous velocity and traction FlinkSQL can create in your organization, to sleepless nights of manual state interventions and unexpected data type inference. The good news is, there are ways to bypass obstacles and tap the most out of FlinkSQL’s benefits by using a Hybrid Flink API approach. We’ll examine the architecture of a fault-tolerant FlinkSQL job (using DLQ), bypass inherent FlinkSQL’s data-type limitations, and finally, show how we can set up our job to handle a massive load. Finally, we’ll also share step-by-step code examples of how to achieve it. ***About the speaker:*** Gal Krispel is a Data Platform Engineer at Riskified, specializing in streaming technologies such as Apache Kafka and Apache Flink. He focuses on building scalable, real-time data pipelines that power Riskified’s core products.

[LinkedIn](https://www.linkedin.com/in/gal-krispel/) **// From Data Mess to Data Products: Unlocking Real‑Time Value with Data Streaming - Ohad Israeli, Senior Solutions Engineer Team Leader at Confluent** This talk shows how organizations can move from brittle, point‑to‑point integrations to a data streaming “central nervous system” that powers reusable, trustworthy data products across both operational and analytical estates. We’ll cover the Stream–Connect–Govern–Process blueprint, pragmatic pipeline patterns into warehouses like Snowflake, and real‑world use cases from fraud detection to personalization—highlighting how reusable data products slash time‑to‑value and operating cost while improving data quality and freshness. Attendees will leave with a practical framework to standardize schemas, materialize real‑time pipelines, and reuse domain data products to accelerate AI/ML and analytics initiatives. ***About the speaker:*** Ohad Israeli is a Senior Solutions Engineer Team Leader at Confluent with 20+ years of experience in data architectures. He helps high‑growth tech teams turn streaming data into measurable outcomes using Confluent. His focus is real‑time, event‑driven architectures, faster paths to production, and reliability at scale. [LinkedIn](https://www.linkedin.com/in/israeliohad/) **// AI vs. Karen: Building Real-Time Sentiment Analysis Pipelines at Scale - Josef Goldstein, Head of R&D, Big Data Platform at Wix** We’ve all heard that “the customer is always right". But let’s be honest, some customers are just impossible to please. What if we could detect them before they turn into ALL-CAPS review bombers, in real-time? In this talk, we’ll walk through how to build AI-powered streaming pipelines using Apache Kafka and Apache Flink that can detect frustrated users and respond in real time at massive scale. We’ll explore how to embed AI models directly into data streams for live inference, discuss the trade-offs between using Large Language Models (LLMs) and Small Language Models (SLMs), and tackle the real-world challenges of latency, scale, and cost optimization in streaming AI architectures. Finally, we’ll demo a live end-to-end example, from data ingestion to AI scoring and visualization, that you can later run on your own setup. ***About the speaker:*** The data and culture guy. Currently leading the Big Data Platform R&D at Wix. Yossi has over 15 years of experience building data intensive SaaS applications and growing the awesome teams that make them. He believes that the secret sauce for creating sustainable complex systems is good design practices, effective communication between people, and automating everything. In his day to day he works tirelessly on building the culture necessary to support these values and propagate them to others, one pep-talk at a time.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? 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: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

You can also join the meeting by Conference Call at (518) 263-8851.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
