Engineering Lakehouses with Open Table Formats
By :
This chapter explored the critical role of catalogs in a lakehouse architecture, detailing their necessity in managing metadata, ensuring consistency across engines, and optimizing performance. We discussed the importance of metadata management, the core features of catalogs, and their integration with table formats such as Apache Iceberg, Delta Lake, and Apache Hudi. The Iceberg REST catalog specification was highlighted as a modern approach to metadata management, emphasizing flexibility, scalability, and interoperability. We also reviewed popular catalog options, such as Hive Metastore, Unity Catalog, Polaris, AWS Glue, and Apache Gravitino, illustrating their unique features and use cases with practical examples.
As data ecosystems grow in complexity, catalogs are pivotal in enabling seamless operations, governance, and multi-engine interoperability, ensuring the lakehouse architecture’s potential is fully realized.
