**TLDR:** An open-standard table structure that supports versioning, transactions, and metadata management for large-scale data lake tables.

<p>Open table formats were developed to provide more reliable table management on top of data lakes. Technologies such as Delta, Iceberg, and Hudi are well-known examples of this approach. They enhance raw file-based storage with advanced capabilities such as transactional safety, time travel, and schema evolution. In modern lakehouse architectures, these formats have become critical building blocks.</p>
