Delta Lake Demo: Introduction

The lakehouse is a simple and open data platform for storing and managing all of your data, that supports all of your analytics and AI use cases. Delta Lake provides the open, reliable, performant and secure foundation for the lakehouse.

It’s an open-source data format and transactional data management system, based on Parquet, that makes your data lake reliable by implementing ACID transactions on top of cloud object storage. Delta Lake tables unify batch and streaming data processing right out of the box. And finally, Delta Lake is designed to be 100% compatible with Apache SparkTM.
