# Table Format

**Canonical:** https://apis.io/providers/table-format/  
**APIs profiled:** 8

Open Table Format is a category of open standards for organizing and managing data in data lakehouses. The three dominant formats are Apache Iceberg (the emerging industry standard with snapshot-based metadata and broad engine support), Delta Lake (Databricks-originated, transaction-log-based), and Apache Hudi (upsert-optimized with Copy-on-Write and Merge-on-Read modes). These formats bring ACID transactions, schema evolution, time travel, and efficient query planning to data lake storage. Apache Iceberg defines a REST Catalog API (OpenAPI spec) that enables standardized catalog operations across implementations like Polaris, Nessie, AWS Glue, and Google BigLake.
