BtrLog: Low-Latency Logging for Cloud Database Systems
Maximilian Kuschewski, Lam-Duy Nguyen, Matthias Jasny +3
Cloud database systems cannot rely on instance-local disks for write-ahead logging (WAL) durability, forcing WAL onto remote storage. Existing options are unsatisfying: remote bloc…
The Bi-Channel Networking Paradigm for Database Systems in the Cloud
Georg Kreuzmayr, Muhammad El-Hindi, Benjamin Wagner +2
When network links were slow, cloud and distributed database systems could rely on generic kernel abstractions and treat network communication as a black box. With today's fast clo…
How to Write to SSDs
Bohyun Lee, Tobias Ziegler, Viktor Leis
This paper demonstrates that adopting out-of-place writes is essential for database systems to fully leverage SSD performance and extend SSD lifespan. We propose a set of out-of-pl…
High-Performance DBMSs with io_uring: When and How to use it
Matthias Jasny, Muhammad El-Hindi, Tobias Ziegler +2
We study how modern database systems can leverage the Linux io_uring interface for efficient, low-overhead I/O. io_uring is an asynchronous system call batching interface that unif…
