Mystery

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.

Join us as we get the New Year started with one of the best films of the year: THE SECRET AGENT! This political thriller from Brazil is set in 1977 where a man flees from a mysterious past and returns to his hometown but soon finds the city is far from being the refuge he seeks. Here’s a description, trailer and plan for this event: DESCRIPTION: In 1977, a former professor flees from a mysterious past and returns to his hometown of Recife in search of peace. He soon realizes that the city is far from being the refuge he seeks.

TRAILER: https://www.youtube.com/watch?v=9UfrzDKrhEc BUZZ & ACCLAIM: The Secret Agent was the most awarded film at the 2025 Cannes Film Festival where it won Best Actor for Wagner Moura, Best Director for Mendonça Filho, the Art House Cinema Award and the FIPRESCI Prize. At this year’s Golden Globes, it became Brazil’s first film ever to be nominated for Best Film (Drama)! It also received a Golden Globe nomination for Best Foreign Film, a Best Actor nomination for Wagner Moura and was selected as Brazil’s entry for Best International Film at this year’s Academy Awards. The film is receiving an incredible 99% positive rating on Rotten Tomatoes where critics say, its “compelling script, impeccable acting, and striking 1970s aesthetic” make it “impossible to look away!” Critics say The Secret Agent is “one of the few standout movies of the year” and the Chicago Tribune calls it a “masterpiece of a film” and “the best film of the year!” PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! PLAN: We’ll plan for a 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! With this being a limited release film, we’ll tentatively plan to see it at the Gateway, but location may change based on where it is showing and the showtimes available. Once details are confirmed, advance ticket is advised. Once you have yours, please list your seat number in the Comments section of this event. Showtime, location and complete details will be confirmed and announced as the date gets closer. Happy New Year and look forward to seeing you there, Dan

Welcome, readers! ❄️ Our December read is **_A Quiet Life by Ethan Joella._** A Quiet Life by Ethan Joella is a tender, character-driven novel that follows three people in a small Pennsylvania town as they each cope with loss and seek connection. Chuck, a widower, struggles to find meaning after his wife’s death; Ella, a young woman, faces the heartbreak of her missing daughter; and Kirsten, a veterinary technician, grieves her father while contemplating her future. Their stories intertwine gently, revealing how grief and hope coexist—and how even small acts of kindness can help people rediscover purpose and peace in the aftermath of tragedy. Looking forward to discussing with everyone! At this meeting, our third annual White Elephant book exchange will take place! If you'd like to participate, bring a gift-wrapped book that you already own. On the gift wrap, write the genre of the book. We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.** Happy reading! 📖
