What is Shannon entropy in data pipelines?

Short version: Measure of info richness in columns. Drops when distributions skew or collapse—catches drift schema ignores.

How does Shannon entropy detect data drift?

Compares today's entropy to baseline. Stability score flags losses; coherence ratios guard transformations. Gates bad loads automatically.

Does Shannon entropy replace schema validation?

Nah—layers on top. Schema for shape, entropy for signal. Together? Unbreakable pipelines.
