On Embedding Database Management System Logic in Operating Systems via Restricted Programming Environments (Matt Butrovich)

Speaker:

Matt Butrovich

The rise in computer storage and network performance means that disk I/O and network communication are often no longer bottlenecks in database management systems (DBMSs). Instead, the overheads associated with operating system (OS) services (e.g., system calls, thread scheduling, and data movement from kernel- space) limit query processing responsiveness. To avoid these overheads, user-space applications prioritizing performance over simplicity can... Read More

[Summer 2023] Towards a Hardware-software Approach for High-performance Databases (Jignesh Patel)

Speaker:

Jignesh Patel

In various industries, in-database analytics are crucial for decision-making. Yet, the growing amount of data presents challenges as traditional methods become excessively time-consuming and costly. Moore's Law and Dennard scaling, which previously aided data-intensive analytics, are reaching their physical limits. A new approach is needed to handle analytics workloads. The speed gap between processing units and memory creates bottlenecks for... Read More

Return of the Database Machines? Towards a Hardware-Software Approach for High-performance Databases (Jignesh Patel)

Speaker:

Jignesh Patel

Analytic database applications have an insatiable appetite for higher performance. In the past, a large part of this appetite was met by leveraging the gift of Moore’s Law. However, the slowing down of Moore’s Law now requires a new approach. Fortunately, the hardware landscape is currently undergoing a Cambrian explosion of new architectures. In this talk, I will describe how... Read More

MS Thesis Defense: High Performance DBMS Design for Intelligent Query Scheduling (Deepayan Patra)

Speaker:

Deepayan Patra

Decades of research in the field of database management systems (DBMSs) have focused on improving system performance with impressive results. Modern analytical databases take advantage of innovative methods such as vectorization and compilation to improve single query performance, use supporting data structures such as indexes or views to reduce data access requirements, and support the execution of multiple queries in...

MS Thesis Defense: Extendable Rule-Based Action Generation for Self-Driving Database Systems (Mike Xu)

Speaker:

Mike Xu

Database management systems (DBMSs) have become more complex to meet increasingly demanding usage. To owners and operators, the need for a self-driving DBMS that can automatically tune and optimize itself without human intervention is apparent now more than ever. Such a self-driving DBMS considers a set of candidate actions to apply to reach a configuration that improves performance for a... Read More
