What is Delta Lake?

Delta Lake is the optimized storage layer that provides the foundation for storing data and tables in the data lake house.

It extends Parquet data files with a file-based transaction log for ACID transactions and scalable metadata handling.

What is ACID and why do we need it?

ACID stands for Atomicity, Consistency, Isolation, and Durability. These four properties are essential for ensuring reliable transaction processing in database systems, and they play a crucial role in data management and data integrity.

In other words, Delta builds the bridge between data warehouse and data lake.

There are two alternatives available:

Apache Hudi: Developed by Uber Engineering, it offers capabilities for managing large-scale data storage with features like record-level insert, update, and delete operations.

Apache Iceberg: Created by Netflix, this platform provides a table format that improves data accessibility and reliability for large analytic datasets.

Which one to choose?

As you may guess overall they all work fine and it depends on your team preference and stack you are having now.
