"Speed" in data engineering is a trade-off, not a single metric. To build effective systems, you must distinguish between two competing concepts: - Data Latency (Freshness): How long it takes for an event to reach your report. - Query Latency (Responsiveness): How long a user waits for a dashboard to load. The Conflict: Optimizing for real-time freshness often slows down query performance because the system can't pre-calculate data. Conversely, pre-calculating data for "snappy" dashboards usually requires batching, which makes data older. The Bottom Line: Reducing latency has exponential costs. Success isn't about being the "fastest"; it's about choosing the right trade-offs between freshness, responsiveness, and budget based on specific business needs.

The paper PropertyGPT explores the use of large language models to generate properties for smart contracts, which is a crucial step in formal verification. Formal verification is a technique that proves the correctness of a system with respect to a certain specification or property. Smart contracts, which manage billions in cryptocurrency assets, require high security and reliability, making formal verification especially valuable. However, existing research lacks automated generation of comprehensive properties, relying on manual writing by experts. The paper proposes using state-of-the-art large language models, such as GPT-4, to transfer existing human-written properties and generate customized properties for unknown code. The process involves embedding existing properties into a vector database and retrieving a reference property for LLM-based in-context learning to generate a new property. The generated properties must be compilable, appropriate, and verifiable, which presents challenges that the paper addresses through various strategies. The authors have implemented these strategies into a novel LLM-based property generation tool called PropertyGPT, which has shown promising results in experiments. PropertyGPT can generate comprehensive and high-quality properties, achieving an 80% recall compared to the ground truth, and has successfully detected vulnerabilities and uncovered zero-day vulnerabilities. The paper was presented at the Network and Distributed System Security Symposium, which aims to foster information exchange among researchers and practitioners of network and distributed system security.
