Why Feature Stores Exist
Solve duplicated logic and training-serving skew.
The Same Feature, Twice
Your training code computes a 7-day average, and your serving code does it again. Two copies of the same logic is where a feature store earns its keep. 🧩
What a Feature Actually Is
A feature is one input signal your model learns from, like a customer's total orders this month. Models eat features, not raw rows.
