Overview

Hello there! This overview will provide a high level summary of what Apache Hudi is and will orient you on how to learn more to get started.

What is Apache Hudi​

Apache Hudi (pronounced "hoodie") pioneered the concept of "transactional data lakes", which is more popularly known today as the data lakehouse architecture. Today, Hudi has grown into an open data lakehouse platform, with a open table format purpose-built for high performance writes on incremental data pipelines and fast query performance due to comprehensive table optimizations.

Hudi brings core database functionality directly to a data lake - tables, transactions, efficient upserts/deletes, advanced indexes, ingestion services, data clustering/compaction optimizations, and concurrency control all while keeping your data in open file formats. Not only is Apache Hudi great for streaming workloads, but it also allows you to create efficient incremental batch pipelines. Apache Hudi can easily be used on any cloud storage platform. Hudi’s advanced performance optimizations, make analytical queries/pipelines faster with any of the popular query engines including, Apache Spark, Flink, Presto, Trino, Hive, etc.

Read the docs for more use case descriptions and check out who's using Hudi, to see how some of the largest data lakes in the world including Uber, Amazon, ByteDance, Robinhood and more are transforming their production data lakes with Hudi.

Hudi-rs is the native Rust implementation for Apache Hudi, which also provides bindings to Python. It expands the use of Apache Hudi for a diverse range of use cases in the non-JVM ecosystems.
