Highlights
Delta Lake is an open-source storage framework that enables building a lakehouse architecture.
Lakehouse is a data management architecture that strives to combine the cost-effectiveness of cheap object storage with a smart management layer.
In simple terms, lakehouse architectures are a collection of files in various formats, with some additional metadata layers on top. These metadata layers aim to provide extra functionality on top of the raw collection of files such as ACID transactions, time travel, partition- and schema evolution, statistics, and much more.
What a lakehouse architecture enables, is to run various types of data-intensive applications such as data analytics and machine learning applications, directly on a vast collection of structured, semi-structured and unstructured data, without the need for an intermediate data warehousing step.
Delta Lake (or simply “Delta”) is currently one of the leading open-source lakehouse formats, along with Apache Iceberg™ and Apache HUDI™.
The easiest way to get a feeling for what a Delta table is, is to think of a Delta table as a “collection of Parquet files with some metadata”.
