Delta Lake

aid: delta-lake
name: Delta Lake
description: Delta Lake is a graduated project of the Linux Foundation AI & Data Foundation providing an open source storage
  framework for building Lakehouse architectures. Originally contributed by Databricks, it adds reliability, quality, and
  performance to data lakes with ACID transactions, schema enforcement, time travel, and Iceberg/Hudi interoperability via
  UniForm. Delta Lake projects also include Delta Sharing (an open protocol for secure data sharing) and catalog-managed tables
  built on the Iceberg REST Catalog protocol.

  name: Delta Lake Storage Framework
  description: The Delta Lake storage framework defines the on-disk transaction log and protocol that adds ACID transactions,
    schema enforcement, and time travel to Parquet-based data lakes. Delta Lake exposes Spark, Rust, and Python APIs (delta-spark,
    delta-rs, deltalake) rather than a network API.
