Session: Enabling Walmart's data lakehouse with Apache Hudi

Ankur Ranjan, Data Engineer III @ Walmart

Ayush Bijawat, Senior Data Engineer @ Walmart

Ankur and Ayush are diving into the strategic shift from data lake to lakehouse architecture at Walmart, with a focus on the importance played by the open table format Apache Hudi. Attendees of this talk will gain a comprehensive understanding of the Hudi architecture, including insights into its underlying file structure, file groups, and the critical timeline feature.

Their session explores the crucial choice between Copy-on-Write (CoW) and Merge-on-Read (MoR) tables, highlighting why CoW tables were chosen for specific use cases. Moreover, the discussion will showcase the various optimization benefits unlocked by Apache Hudi, such as file resizing, enhanced UPSERT and DELETE support, schema evaluation, and partial updates.

The session also offers a practical perspective on enabling Apache Hudi within the Google BigQuery ecosystem, making it a must-attend event for those seeking to leverage cutting-edge data management solutions.
