What is Shannon entropy in data pipelines ?

It measures a column's information content — how much uncertainty or diversity it holds. Drops signal data quality issues like skew or collapse that schema misses.

How does Shannon entropy detect data drift ?

By comparing today's distribution entropy to a baseline. Score below threshold

Does Shannon entropy replace schema validation?

Nope — complements it. Schema checks shape; entropy checks substance. Use both for bulletproof pipelines.
