Iceberg and Hudi ACID Guarantees

In this post, I make the case that Apache Iceberg is reliable and Apache Hudi is not. And the best way to do that is to contrast the design of both projects in the context of the ACID guarantees: atomicity, consistency, isolation, and durability. My aim is to accurately present the facts to educate the curious and help people make informed choices.

The Case for Independent Storage

Analytic databases are quietly going through an unprecedented transformation — one that will fundamentally change the industry for the better, by freeing data that’s being held hostage.

Metadata Indexing in Iceberg

This post details how Iceberg’s metadata forms an index that Iceberg uses to scale to hundreds of petabytes in a single table and to quickly find matching data, even on a single node.

Tabular and the Iceberg Community

To be successful, the Iceberg community needs to be collaborative, neutral, and independent. To ensure that it continues to be a healthy and successful community, we're creating an open source culture at Tabular that sets best practices for working in the community.

Introducing Tabular

Introducing Tabular. We think data engineers, analysts, and scientists are most effective when they can focus on building reliable data products and answering questions, not fighting infrastructure. We’re creating a new data platform that automates maintenance and optimization to protect people from tedious concerns, while enabling them to work with the same data simultaneously across Spark, Trino, Flink, and other engines. The core of Tabular is the open source standard for huge analytic tables, Apache Iceberg.
