Lakehouse models prioritize data security and make it easier to apply governance mechanisms that enable people to work with data they need, but also adhere to regulatory compliance standards at a global scale.ĭata warehouse vs. Add in the single-source repository model of data warehouses and enterprises can consolidate data to keep costs under control. Utilizing standardized object storage solutions, data lakehouses offer the same cost-effectiveness and control as data lakes. As a result, organizations can move away from hybrid lake-warehouse models that see data duplicated to ensure accessibility. Because data lakehouses combine the functions of lakes and warehouses, they offer an all-purpose storage platform that can handle any type of data. The most common advantages of data lakehouses include the following: What are the advantages of a data lakehouse? Data lakehouses support multiple use cases around analytics and machine learning, such as exploratory analytics to answer ad-hoc questions. Massively parallel processing allows distributed query execution by multiple processors to speed up the response. This is simply not possible with conventional architectures. Data lakehouses deliver the query response with minimal latency. The performance of these queries needs to be at a level where they can support ad-hoc analytics use cases. Data lakehouses offer a way to interrogate the data and send processing instructions in the form of queries. Data lakehouses take advantage of low-cost object stores like AWS S3 or Microsoft Azure Blob Storage to store and manage data cost-effectively. Agent and open technologies make it easy to ingest large volumes of observability, security, and business data. Data lakehouses ingest large structured and unstructured data volumes at a very high speed in their raw, native form. While the specifics of data lakehouses differ based on business objectives and use cases, the following five features are fundamental: What are the features of a data lakehouse?

Then, a subset of this data seamlessly filters through to become more curated and trusted data sets on which organizations set the required governance, use, and access rules. In a data lakehouse model, organizations first migrate data from sources into a data lake. The result is a framework that offers a single source of truth and enables companies to make the most of advanced analytics capabilities simultaneously. Generally, the storage technology categorizes data into landing, raw, and curated zones depending on its consumption readiness.

Therefore, it contains all of an organization’s data. A data lakehouse provides a cost-effective storage layer for both structured and unstructured data. This data lands in its original, raw form without requiring schema definition. These include application programming interfaces, streaming, and more. So, usage can become overwhelming if organizations do not carefully manage it.ĭata lakehouses typically provide support for data ingestion through a variety of methods. Unlike data warehouses, however, data is not transformed before landing in storage. This approach enables organizations to use this data to build artificial intelligence (AI) and machine learning models from large volumes of disparate data sets. However, organizations must structure and store data inputs in a specific format to enable extract, transform, and load processes, and efficiently query this data.ĭata lakes, meanwhile, are flexible environments that can store both structured and unstructured data in its raw, native form. What is a data lakehouse?Ī data lakehouse features the flexibility and cost-efficiency of a data lake with the contextual and high-speed querying capabilities of a data warehouse.ĭata warehouses offer a single storage repository for structured data and provide a source of truth for organizations. Let’s explore what constitutes a data lakehouse, how it works, its pros and cons, and how it differs from data lakes and data warehouses. While data lakes and data warehousing architectures are commonly used modes for storing and analyzing data, a data lakehouse is an efficient third way to store and analyze data that unifies the two architectures while preserving the benefits of both.Ī data lakehouse, therefore, enables organizations to get the best of both worlds.īut before your data moves into its data lakehouse, it’s important to understand what this architecture looks like in practice. With a data lakehouse, organizations get the best of data lakes and data warehouses. Today's organizations need a place to store massive amounts of structured and unstructured data.
