Overview
An architectural pattern used to implement access to data that is based on open direct-access data formats (such as Apache Parquet and ORC), has support for machine learning and data science and offers state-of-the-art performance. The implementation of a Lakehouse pattern is a data management system, which provides traditional analytical DBMS management and performance features such as ACID transactions, data versioning, auditing, indexing, caching and query optimization. It hovers of a Data Lake and combines its key benefits with those of a data warehouse. Works well with cloud environment where compute and storage are separated.
A lakehouse stores data in low-cost objects stores (S3) using a standard file format such as Apache Parquet
