Delta Lake and Delta Engine guide
Delta Lake is an open source storage layer that brings reliability to data lakes. Delta Lake 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. Delta Lake on Azure Databricks allows you to configure Delta Lake based on your workload patterns.
Azure Databricks also includes Delta Engine, which provides optimized layouts and indexes for fast interactive queries.
