A feed has a strict schema contract with the producing team: the ingested table must contain exactly the agreed columns, and anything the producer adds outside the contract must be captured for review rather than silently appearing in the table. The ingestion uses Auto Loader. How should the stream be configured?
Reveal answer
Correct answer: Supply the agreed schema explicitly with evolution off; unexpected columns then land in the rescued data column

The “Sphere Embrace”: how Noos embraces top contributors without a childish mascot.
In neurobiology, glial cells wrap axons in myelin sheaths to accelerate neural impulses. On Noos, as your explanations earn accelerations and enter the Wiki Synthesis, the Noos Sphere wraps your Identicon with Keplerian orbits and two quantum nodes on its shoulders.
Pure 5×5 geometric Identicon (no personal photo, zero tracking). 1px frame.
Single dashed orbit with 1 bright polar node at the apex. Highlights those who passed the exam.
Two coaxial ellipses (±35°) wrap the avatar with two lateral nodes.
The Sphere Embrace: The Noos Sphere hood wraps the top of the Identicon and rests two luminous nodes on its shoulders.
