Managing Lakehouse Data

Harsha Gummadavelli gives us an introduction to the Data Lakehouse concept:

“Data Lakehouse” is a new architecture paradigm in the data management space that combines the best characteristics of Data Warehouse and Data Lakes. Once you load the data into a data lake, there is no need to load the data into a warehouse for additional analysis or business intelligence. You can directly query the data residing in cheaper but highly reliable storage, often termed as “Object Stores”, thus reducing the operational overhead on data pipelines.

I will say that I’m not particularly sold on the data lakehouse concept at this point. It’s interesting, in that it reduces the number of systems to maintain by one, but I do wonder about performance issues when trying to replace an existing warehouse. The post turns into a marketing pitch for Informatica, but the first half does give a fair introduction to the concept.
