Today Question:
“Data Lakehouse” combines features of:
A) Lake + Warehouse
B) OLTP + OLAP
C) Kafka + Spark
D) Hadoop + Hive
Correct Answer: A
Explanation
A Data Lakehouse is a modern data architecture that integrates the strengths of a Data Lake and a Data Warehouse. From the Data Lake it inherits the ability to store massive volumes of raw, structured, and unstructured data at low cost. From the Data Warehouse it inherits optimized analytical query performance with transactional consistency. A Lakehouse provides a unified platform for both batch and stream processing, simplifies ETL processes, reduces latency, and eliminates data duplication across systems. This approach increases flexibility, scalability, and efficiency compared to traditional architectures where lake and warehouse exist as separate systems.
