This includes robust auditing of data and data access control. Schema enforcement and data governance, which ensures new data follows the schema of the target table to reduce data quality issues.Durability: Durability ensures that when a transaction completes, it’s saved and not lost with any system failure.From a user’s perspective, it feels like these transactions occur one by one when they’re being executed at the same time. ![]() Isolation ensures those transactions don’t interfere with or affect any other transaction. Isolation: Transaction-whether they be reads or writes-typically occur concurrently with many different users.Transactional consistency ensures that any corruption that occurs doesn’t have an unintended effect on the table or other data. Consistency: When a transaction occurs, this ensures tables change in predictable ways.This property prevents data loss and corruption from occurring, increasing trust in the data. Atomicity: Each transaction-whether it be read, write, update, or delete-is treated as a single unit and must execute in its entirety or not at all.ACID transaction support, which ensures data consistency between concurrent read and writes, increasing the trustworthiness of the data.The other part is open APIs to access the data stored in the storage layer, allowing users-from business analysts to data scientists-the ability to access data using SQL, Python, Scala or R, to name a few. Open file formats in the data lake, such as Apache Parquet and ORC, are a part of this open-source approach. Open source, which enables organizations to build on different tools from different vendors, effectively removing the all-too-common vendor lock-in that occurs with data management technologies.Handles structured and unstructured data, which allows for the collection of data from traditional transaction data to images, video, and text.Key features of a data lakehouse include: What is a Data Lakehouse?Ī data lakehouse is a new data management architectural pattern that combines the low-cost, scalability, and flexibility of a data lake with the data management and data structure of a data warehouse. We will also go over the steps you can take to better understand if it is the right solution for your organization and cover the technology you can use to build one. ![]() ![]() In this blog, we will explain what makes a data lakehouse different from a data warehouse and a data lake and discuss a pragmatic approach to data lakehouse architecture. The need for a better approach to data management has led to new solutions like the data lakehouse.īut what makes a data lakehouse different, how can it fit into your existing architecture, and how can it help your organization do more with the data you own? Many organizations lack the ability to gain actionable insights from all their data because it is often spread across multiple systems-data warehouses, data lakes, or a combination of both. Learn about data lakehouse features, architecture, technology, and if it could be a good fit for your organization.Īs the rate at which companies collect data continues to grow, the volume and variability of this data has proven difficult to manage using existing data warehouse and data lake architectures. The data lakehouse was created to combine the benefits of a data warehouse and a data lake.
