Introduction to Delta Lake

Delta Lake is an open-source storage layer that brings reliability to data lakes. It provides ACID transactions, scalable metadata handling, and unifies streaming and batch data processing. Delta Lake runs on top of your existing data lake and is fully compatible with Apache Spark APIs. This ensures that you can easily migrate your existing workloads to Delta Lake without any major changes.

One of the key advantages of Delta Lake is its ability to bring consistency to your big data workloads. By providing ACID transactions on big data, Delta Lake enables concurrent reads and writes, ensuring data integrity and consistency. This is particularly important in scenarios where multiple users or applications are reading and writing to the same data lake concurrently.

Delta Lake also simplifies the process of managing schema evolution in your data lake. With Delta Lake, you can easily evolve your data schemas without breaking your existing pipelines. This helps in maintaining data quality and consistency over time, even as your data evolves.

Overall, Delta Lake is a powerful tool for building reliable and scalable data pipelines on your data lake. By providing ACID transactions, scalable metadata handling, and unified batch and streaming processing, Delta Lake simplifies the process of building and managing big data workloads.
