An Auto Loader stream runs with an inferred schema. In today's batch, some records use a column name with different casing (OrderID instead of order_id), and one field's value does not match the type Auto Loader inferred for it. Where does this non-conforming data end up?
Reveal answer
Correct answer: They land in the _rescued_data column Auto Loader adds automatically — non-conforming fields plus the source file path

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.
