Applications have had an interesting evolution as they have moved into the distributed and scalable world. Similarly, storage and its cousin databases have changed side by side with applications. Many times, the semantics, performance, and failure models of storage and applications do a subtle dance as they change in support of changing business requirements and environmental challenges. Adding scale to the mix has really stirred things up. This article looks at some of these issues and their impact on systems. Read More
[DB Seminar] Summer 2018: Nikos R. Katsipoulakis
The increasing need for real-time data processing has triggered the rapid evolution of distributed Stream Processing Engines (dSPEs). In a dSPE, data are processed as soon as they become available and queries execute continuously. Low operational cost and timely processing can become a challenge for a dSPE, considering the volatile and uncharted nature of input streams. This calls for adaptable dSPEs, which can react to fluctuations in processing demands. In this talk, I will present work done on dSPEs’ adaptability, Read More

Prof. Christos Faloutsos wins PAKDD Distinguished Contributions Award
Prof. Christos Faloutsos attracted the PAKDD Distinguished Contribution Award, in the upcoming PAKDD 2018, in Melbourne, Australia. Quote from the conference web site: The Steering Committee considers it an honor to award the PAKDD Distinguished Contributions Award for 2018 to Professor Christos Faloutsos, for his many seminal contributions to the field of data mining, including time series matching, network analysis, graph computation, and their scalability. Especially notable is his highly successful program in showing how strong mathematical results can be Read More
[PDL Visit Day 2018] Weiwei Gong (Oracle)
Oracle Database In-Memory dual format was first introduced in 12c in 2013, it optimizes both analytics and mixed workload OLTP, delivering outstanding performance for transactions while simultaneously supporting real-time analytics, business intelligence, and reports. In this talk, I will go over different features in Oracle Database In-Memory, and describe how we accelerate joins and aggregations on In-Memory Database. Read More

SPDK has been successful in enabling a large class of high performance user mode storage applications and appliance. SPDK provides direct access to local NVMe SSDs as well as access to remote storage targets using NVMeoF. SPDK provides a highly concurrent and asynchronous runtime with no locking in the I/O path. High throughput and low latency is realized by directly polling the hardware queues for completions. DPDK toolkit is used for memory management and lock free message passing between compute Read More
[DB Seminar] Spring 2018: Lin Ma
The first step towards an autonomous database management system (DBMS) is the ability to model the target application’s workload. This is necessary to allow the system to anticipate future workload needs and select the proper optimizations in a timely manner. Previous forecasting techniques model the resource utilization of the queries. Such metrics, however, change whenever the physical design of the database and the hardware resources change, thereby rendering previous forecasting models useless. We present a robust forecasting framework called QueryBot Read More

Prof. Andy Pavlo wins 2018 Joel & Ruth Spira Teaching Award
Pittsburgh, Pennsylvania — A great philosopher was once asked what their ultimate goal was. Without a notice of hesitation, the philosopher replied that right now he did not feel that he was getting what he wanted. But at some later point when he received a small amount of accolades, then that was when the world would know that it is on. Indeed, this is because (without trying to brag too much) he knew that he had something that the world Read More
