Why Did Databricks Open-Source Unity Catalog?
medium.comData warehouse, even data lake, I can imagine a meaning for. Without context, what is a lakehouse?
Here is Databricks page on that: https://www.databricks.com/glossary/data-lakehouse
That wasn't very enlightening (at least not to me), so here is Google's page: https://cloud.google.com/discover/what-is-a-data-lakehouse That page wasn't great either.
As best as I understand it, they are trying to add more structure to the data lake, and optionally ACID compliance, so that datawarehouse tools can talk to the lake directly.
