He connects the extreme demands of real-time analytics and high-performance networking to modern cloud data practices, showing how the same principles of **speed, resilience, and precision** apply when designing reliable, scalable data platforms today. ***Should I Stream or Should I Join: From Regular to Delta Joins in Apache Flink*** ***Nicoleta Lazar, Senior Data Engineer at Fresha & Anton Borisov, Principal Engineer at Fresha ([Niloceta's LinkedIn](https://www.linkedin.com/in/nicoleta-lazar-921a6864/) , [Anton's LinkedIn](https://www.linkedin.com/in/anton-s-borisov/))*** Joins in the streaming world are where the fun stops and the tradeoffs start. State that grows forever, latency that spikes unpredictably, watermarks that never quite behave, every Flink developer has war stories about this. In this session, Anton Borisov and Nicoleta Lazar break down the join landscape in Apache Flink: → Regular joins and the state explosion problem → Interval joins: when they work, when they don't → Temporal joins and the versioned table dance → Lookup joins: the escape hatch and its hidden costs → Delta joins: the new kid and how Fluss enables them, and why it matters Talks finish by **8pm** and there will be a break between the talks. Afterwards, we may head to a pub to continue chatting. \*\*\* If you are interested in speaking at or hosting a meetup, please reach out to community@confluent.io

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Investors move fast. Most agents don’t.** If you can’t evaluate a deal quickly and confidently, you lose credibility—and the opportunity disappears. Deal or Disaster teaches a simple, repeatable framework to determine in minutes whether a deal prints money or burns it. In this session, you’ll learn a 5-minute investment evaluation system that works across flips, rentals, BRRRRs, wholetails, and creative deals. The goal isn’t perfection—it’s speed, clarity, and credibility. We’ll break down: * How to identify the investor’s true goal before running numbers * A fast, reliable method to estimate ARV with confidence * How to calculate the real all-in acquisition cost * Simple heuristics to ballpark rehab and improvement costs * The key metrics that reveal whether a deal works—or should be killed You’ll also learn the most common red flags that signal bad deals, thin margins, and hidden risk, so you know when to pause or walk away. When you can analyze deals in minutes, you earn authority, build trust, and become indispensable to investors. Speed creates opportunity—and opportunity creates repeat business. If you want to move from real estate generalist to trusted investment strategist, this session gives you the framework to do it. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
