Presto Videos: Talks, Webinars, and Events (On Demand)

Apache Hudi is a rich platform to build self-managing, exabyte-scale data lakes, optimized for incremental as well as regular batch processing. Hudi tables can be seamlessly synced to Hive metastore, which unlocks the powerful capabilities of Presto engine via the Hive connector. Presto-Hudi integration is over five years old. What started as simply fetching splits using a custom input format for a Hudi Copy-On-Write table has evolved into snapshot querying of Merge-On-Read tables and using Hudi’s internal metadata table to boost query performance. In this session, we trace that journey and discuss in detail the recent developments that have made this integration stronger not only in terms of usability but also performance. We discuss the additional features that come with the brand new presto-hudi connector, such as multi-modal index and data skipping for better query performance.
