[DB Seminar] Summer 2019 DB Group: Yangjun Sheng

Jun 21, 2019

Yangjun will give a practice talk for the SIGMOD/AiDM workshop.   Title: Scheduling OLTP Transactions via Learned Abort Prediction   Abstract: Current main memory database system architectures are still challenged by high contention workloads and this challenge will continue to grow as the number of cores in processors continues to increase. These systems schedule transactions randomly across cores to maximize concurrency and to produce a uniform load across cores. Scheduling never considers potential conflicts. Performance could be improved if scheduling balanced between Read More

[DB Seminar] Summer 2019: Lucas Lersch (TU Dresden)

Non-volatile memory technologies (NVM) enable persistent media to be directly accessed by the CPU through its caches. The biggest challenge introduced by NVM is the little control the application has when persisting data. This stems from the fact that it is not possible to prevent data from being evicted from the CPU cache to NVM at arbitrary points in time, possibly leading to corruption. To deal with this problem, work so far treat NVM either like storage (by always writing Read More

[DB Seminar] Spring 2019 Reading Group: Laxman Dhulipala

May 10, 2019

Abstract:I will provide a broad overview of graph databases, from the earlydays of database research, to their adolescence and experimentationwith RDF, and finally to the current bloom of graph and multi-modelDBs available today. I will also try to defuse the hype around graphdatabases, and try to articulate scenarios where using such a databasecould be useful.Time permitting, I will provide a high-level overview of our recentwork on Aspen, a principled graph-streaming system that extends Ligrawith primitives for updating a graph.

PDL Visit Day 2019: Luis Remis (Intel)

May 5, 2019

We introduce the Visual Data Management System (VDMS), which enables faster access to big-visual-data and adds support to visual analytics. This is achieved by searching for relevant visual data via metadata stored as a graph, and enabling faster access to visual data through new machine-friendly storage formats. VDMS differs from existing large scale photo serving, video streaming, and textual big-data management systems due to its primary focus on supporting machine learning and data analytics pipelines that use visual data (images, Read More

PDL Visit Day 2019: Pat Helland (SalesForce)

May 5, 2019

If you squint hard enough, many of the challenges of distributed computing appear similar to the work done by the great physicists. Dang, those fellows were smart! Here, I examine some of the most important physics breakthroughs and draw some whimsical parallels to phenomena in the world of computing... just for fun. Read More
