Apache Calcite is a foundational software framework that provides query processing,
optimization, and query language support to many popular open-source data processing …

This paper presents a new view of federated databases to address the growing need for
managing information that spans multiple data models. This trend is fueled by the …

This paper presents the design of a read-optimized relational DBMS that contrasts sharply
with most current systems, which are write-optimized. Among the many differences in its …

We study the problem of computing conjunctive queries over large databases on parallel
architectures without shared storage. Using the structure of such a query q and the skew in …

In previous papers [SC05, SBC+ 07], some of us predicted the end of" one size fits all" as a

Online Transaction Processing (OLTP) databases include a suite of features---disk-resident
B-trees and heap files, locking-based concurrency control, support for multi-threading---that …

Protected database search systems cryptographically isolate the roles of reading from,
writing to, and administering the database. This separation limits unnecessary administrator …

Data federation addresses the problem of uniformly accessing multiple, possibly
