Extract-Transform-Load for Video Streams
Ferdinand Kossmann, Ziniu Wu, Eugenie Lai +4
Social media, self-driving cars, and traffic cameras produce video streams at large scales and cheap cost. However, storing and querying video at such scales is prohibitively expen…
Parallel External Sorting of ASCII Records Using Learned Models
Ani Kristo, Tim Kraska
External sorting is at the core of many operations in large-scale database systems, such as ordering and aggregation queries for large result sets, building indexes, sort-merge joi…
FactorJoin: A New Cardinality Estimation Framework for Join Queries
Ziniu Wu, Parimarjan Negi, Mohammad Alizadeh +2
Cardinality estimation is one of the most fundamental and challenging problems in query optimization. Neither classical nor learning-based methods yield satisfactory performance wh…
LSI: A Learned Secondary Index Structure
Andreas Kipf, Dominik Horn, Pascal Pfeil +2
Learned index structures have been shown to achieve favorable lookup performance and space consumption compared to their traditional counterparts such as B-trees. However, most lea…
Bounding the Last Mile: Efficient Learned String Indexing
Benjamin Spector, Andreas Kipf, Kapil Vaidya +3
We introduce the RadixStringSpline (RSS) learned index structure for efficiently indexing strings. RSS is a tree of radix splines each indexing a fixed number of bytes. RSS approac…
The Case for Learned In-Memory Joins
Ibrahim Sabek, Tim Kraska
In-memory join is an essential operator in any database engine. It has been extensively investigated in the database literature. In this paper, we study whether exploiting the CDF-…
