Abstract

Approximate Nearest Neighbor (ANN) vector search has been a fundamental block in multiple applications. As recent AI breakthroughs enable developers to create GenAI applications that benefit from the context provided by the database, we expect that multiple database vendors will expand their offerings with ANN vector indexing. When structured data querying and disk-based storage meet semantic vector search, challenges and opportunities emerge motivated by performance/cost, ease-of-use (SQL's declarativeness) and novel functionalities. Our discussion will overview these opportunities.

Short Bio

 Yannis Papakonstantinou is a Distinguished Engineer, working on Query Processing and GenAI, at Google Cloud. He is also an Adjunct Professor of Computer Science and Engineering at the University of California, San Diego, following many years of having been a UCSD regular faculty member. Previously he was an architect in query processing & ETL at Databricks. Earlier, he was a Senior Principal Scientist at Amazon Web Services from 2018-2021 and was a consultant for AWS since 2016. He was the CEO and Chief Scientist of Enosys Software, which built and commercialized an early Enterprise Information Integration platform for structured and semistructured data. The Enosys Software was OEM'd and sold under the BEA Liquid Data and BEA Aqualogic brand names, eventually acquired in 2003 by BEA Systems. His R&D work has been mostly on query processing with focus on querying semistructured data. He has published over one hundred twenty research articles that have received over 20,000 citations. Yannis holds a Diploma of Electrical Engineering from the National Technical University of Athens, MS and Ph.D. in Computer Science from Stanford University (1997).
