Описание: In this talk, we present a recent extension to Prestissimo to support AI training data normalization at Meta. We describe the AI Data Storage system built at Meta to deduplicate user sequence data and enable fast retrieval of aggregated data in different dimensions. We then deep dive into the changes made to Prestissimo to allow user sequence data exploration through Presto SQL, including the introduction of a new Index Join Operator and AI Data Storage Connector. Our extension enables optimized index join query plan generation and end-to-end query execution optimization.
