An Introduction to Delta Lake

Exploring open source storage layer that brings reliability to data lakes

Data Lakes built using Hadoop framework were lacking a very basic functionality i.e. ACID compliance. Hive tried to overcome some of the limitations by providing update functionality but the overall process was messy. Databricks (the company behind Spark) came up with a unique solution i.e. Delta Lake. Delta Lake enables ACID transactions over existing Data Lakes. It can seamlessly integrate with many Big Data Frameworks like Spark, Presto, Athena, Redshift, Snowflake etc. Let’s explore this interesting technology more.

It is an Open source storage layer that provides reliability to the data lakes. Delta Lakes provides ACID(Atomicity, Consistency, Integrity and Durability) properties, scalable metadata handling, and unifies streaming and batch data processing. It runs on the top of data lakes and it is fully compatible with Spark APIs. Data in Delta Lake is stored in Parquet format. It enables Delta Lake to leverage the efficient compression and encoding schemes that are native to Parquet.
