Excited to share our latest paper in collaboration with Snowflake! Congratulations to my PhD student, @andizimmerer.bsky.social, on his first SIGMOD publication, and many thanks to Snowflake for their support—both in providing essential statistics and championing the work.
"The fastest way of processing data is to not process it."
Our SIGMOD 2025 paper shows how Snowflake skips 99.4% of data with new pruning techniques for LIMIT, top-k, and JOIN queries.
