Plain Talk Data: Lakehouse
A plain-English explanation of what a Lakehouse is - the garage that finally got organized
Lakehouse = “The garage that finally got organized”
Remember how we said a data lake is like your messy garage where you just toss everything? Well, a lakehouse is what happens when you finally buy some shelving units and label makers, but you don’t throw anything away.
Here’s the evolution:
Data Lake (messy garage):
- Cheap storage for everything
- Good luck finding anything
- Raw files everywhere: photos, videos, sensor data, spreadsheets
- Great for “someday I might need this”
Data Warehouse (organized filing cabinet):
- Everything perfectly sorted and clean
- Lightning fast to find stuff
- Expensive to maintain
- But you had to throw out a lot of stuff to make it fit
Lakehouse (organized garage with good shelving):
- Keep ALL your junk like the lake
- But add smart organization like the warehouse
- You can find your Christmas lights AND your tax reports
- Costs way less than the fancy filing cabinet
The magic trick: Instead of moving all your data to expensive warehouse storage, you just add a smart catalog system on top of your cheap lake storage. It’s like putting up shelves and signs in your garage without having to rent a storage unit.
Real example: Netflix keeps every single click, view, pause, and rewind in their lakehouse. Cheap storage for the raw stuff, but organized enough that they can instantly tell you “people who watched this also liked that.”
Bottom line: You get the “store everything cheap” benefits of a lake with the “find stuff fast” benefits of a warehouse. It’s like having your cake and eating it too, except the cake is made of data and costs 80% less.
