![]() ![]() It lets them reach a middle ground where they can get the best of both worlds in terms of data storage and data management. end-to-end streaming (that allows to build real-time applications)Ĭommercial Data Lakehouse solutions leveraging DataBricks tool are available on all main cloud platforms: Azure, AWS, and GCPĪ data lakehouse concept can help organizations move past the limitations of data warehouses and data lakes.support for diverse workloads (they all rely on the same repository). ![]() openness (usage of open format like parquet files, and providing an API for a variety of tools like Python/R/etc.).BI support (we can build BI tools directly on top of source data).The main features of Data Lakehouse include: They implement similar data structures and data management features to the ones in a data warehouse, however it is all built on top of low-cost storage in open formats. The diagram below compares data warehouse, data lake and data lakehouse architectures.ĭata Lakehouses represent a new, modern design. Data lakehouses implement data warehouses’ data structures and management features for data lakes, which are typically more cost-effective for data storage. The need for a flexible, high-performance system enforced a new approach and finally led to the introduction of the Data Lakehouse concept.Ī data lakehouse is a new, open data management architecture that combines the flexibility, cost-efficiency, and scale of data lakes with the data management and ACID transactions of data warehouses, enabling business intelligence (BI) and machine learning (ML) on all data. Therefore data lakes lead to a loss of many benefits of standard data warehouses. Data lakes proved to be a good solution for storing unstructured data, but there was a problem with supporting transactions, enforcement of data quality, and lack of consistency. The need to store and process unstructured data led to the invention of data lakes – repositories for raw data in a variety of formats. Data warehouses were not fully suited for these needs, and – for sure – were not the most cost efficient. However, while data warehouses were great for storing and processing of structured data, today lots of companies have to deal with unstructured or semi-structured data with high variety, velocity and volume. They were designed to handle large data sizes, providing the possibility to store structured data, optimized for analytics. Typical data warehouses were introduced in the 1980s. It utilizes the standard data warehousing approach, and combines it with all the advantages of data lake. Data lakehouse architecture is a modern approach to building data warehousing systems. ![]()
