00:00:00 Explore the history of data management and Analytics to understand what a data lakehouse is. Learn about the challenges of managing Big Data and the purpose of a data lakehouse.

๐Ÿข Data lakes emerged as a solution for managing big data at high volumes and faster pace.

๐Ÿ’ก Data warehouses were designed to collect and consolidate structured data for business intelligence and analytics.

๐Ÿ’ฐ Data lakes provide a more cost-effective solution for storing and analyzing semi-structured and unstructured data.

00:01:05 An introduction to data lakehouses, which emerged as a solution to handle large volumes and various types of data. However, they lack transactional support and data quality enforcement.

๐Ÿ’ก Data warehouses were no longer suitable for handling the increasing volume, velocity, and variety of digital data.

๐Ÿ’ก Data Lakes emerged as a solution, allowing the storage of structured, semi-structured, and unstructured data from various sources.

๐Ÿ’ก However, Data Lakes lack features such as transactional support and data quality enforcement, raising concerns about the reliability of the stored data.

00:02:09 Introduction to the challenges of data analysis in large volumes and unstructured data lakes, and the need for integrated systems for reliable insights and AI implementation.

๐Ÿ”‘ Data lakes face challenges with performance, timeliness, and governance due to large volume and unstructured nature of data.

๐ŸŒŠ Businesses use complex technology stack environments, including data lakes, data warehouses, and specialized systems, which introduce complexity and delay.

๐Ÿ’ก Successful AI implementation and actionable outcomes are hindered by the difficulties in managing data and oversight in disjointed systems.

00:03:11 The data lake house is an open architecture that combines the benefits of a data lake with the analytical power of a data warehouse. It provides a single reliable source of truth for data exploration, predictive analytics, and real-time analysis.

๐Ÿ“Š Only 32 percent of companies reported measurable value from data.

๐Ÿ’ก Data teams needed systems to support data applications including SQL analytics, real-time analysis, data science, and machine learning.

๐Ÿ  The data lake house combines the benefits of a data lake with the analytical power and controls of a data warehouse.

00:04:14 An overview of the key features of data lakehouses, including transaction support, schema enforcement, data governance, decoupled storage from compute, open storage formats, support for diverse data types, and diverse workloads.

๐Ÿ”‘ Data lakehouses offer key features like transaction support, schema enforcement, data governance, and decoupled storage.

๐ŸŒŠ Open storage formats like Apache Parquet enable efficient access to diverse data types in a data lakehouse.

๐Ÿ” Data lakehouses support diverse workloads, including data science, machine learning, and SQL analytics.

00:05:18 Data Lakehouse is a modernized version of a data warehouse that supports data analysts, engineers, and scientists in one location, without compromising flexibility and depth.

๐Ÿ’ก Data lakehouse replaces the need for a separate system for real-time data applications.

๐Ÿข Data analysts, engineers, and scientists can all work in a single location with the lakehouse.

๐ŸŒŠ The lakehouse combines the benefits of a data warehouse with the flexibility of a data lake.
