🧠 Feynman Takeaway

StreamNative Launches Lakestream + Ursa for Kafka
In plain English
StreamNative published the defining data engineering architecture of 2026: Lakestream — a single copy of data in Kafka topics that simultaneously serves real-time streaming and Iceberg table queries. Ursa for Kafka provides native Kafka on lakehouse storage with 95% cost reduction by eliminating separate streaming and batch storage.
Analogy
Imagine having two refrigerators — one for tonight's dinner, one for next month's meal prep. Lakestream says: use one refrigerator for both. Same food, same fridge, same cost. The 95% cost reduction comes from not buying a second fridge.
Why it matters
This wasn't just a product launch — it was a paradigm shift. The batch/streaming duality that had plagued data architecture for a decade was finally resolved. One copy of data, two access patterns.
