What is the main purpose of using Delta Lake in Databricks?

The main purpose of using Delta Lake in Databricks is to enable ACID transactions and scalable data management. Delta Lake is an open-source storage layer that brings reliability to data lakes by providing features that are traditionally associated with database systems. ACID transactions ensure that all operations on data are executed in a reliable manner, maintaining data integrity even in the event of failures or concurrent operations.

Delta Lake also supports scalable data management through features such as schema enforcement, time travel (the ability to access previous versions of data), and improved data governance. These capabilities allow organizations to manage large volumes of data efficiently and safely, making it possible to handle complex analytics workloads without sacrificing performance or reliability.

Enhancements provided by Delta Lake are not limited to small datasets; instead, they cater to large-scale enterprise data workloads. While Delta Lake can work well alongside traditional databases, its primary function is to enhance the functionality of data lakes rather than replace them or other storage systems entirely.
