Project 1: Storage Engine (Tianyu Li & Matt Butrovich) In this talk, we will discuss the work we've done on terrier's storage engine over the semester. We will cover the implementation of write-ahead logging and our proposed model for recovery, implementation of indexes, and our roadmap for the storage engine next semester. The immediate future direction for the storage work... Read More

Following from the idea that "one size no longer fits for all", a family of "NewSQL" specialized databases arose. To handle OLTP, researchers at MIT and Brown (and a few other places) built H-Store, a distributed, shared-nothing, in-memory database that got rid of locking, latching, buffering, and logging, beating the performance of traditional OLTP RDBMSs by nearly two orders of...

n the last two decades, both researchers and vendors have built advisory tools to assist database administrators (DBAs) in various aspects of system tuning and physical design. Most of this previous work, however, is incomplete because they still require humans to make the final decisions about any changes to the database and are reactionary measures that fix problems after they...

The Swarm64 Data Accelerator (S64 DA): Processing OLAP Workloads of Open-Source SQL-Databases with CPU+FPGA Cooperative Computing (Karsten Rönner)

Online Analytical Processing (OLAP) of very large data sets and/or high-velocity data is a workload that strains all parts of a compute system: storage bandwidth, IO-subsystem throughput, main-memory bandwidth, instruction-level concurrency and thread-parallelism. Swarm64 seeks to improve the effective throughput and the compute efficiency of OLAP workloads by adding FPGAs as additional compute element to standard compute servers. The hard-... Read More

Modern query-heavy applications of database systems especially require minimal delays to OLAP queries, as well as allowing the lasted OLTP updates to be visible in time. A popular mechanism for fast response to OLAP queries is to use snapshot isolation (SI) for multi-version concurrency control (MVCC), as it allows readers to make progress regardless of concurrent writers. Many other optimizations... Read More

Using GPU Databases to Build the Next Generation of Artificial Intelligence (Richard Heyns)

In this talk, we will cover how the implementation of GPU database management systems are different than CPU database systems and provide evidence that shows how much of the performance gains with these systems are achieved via just GPUs. We will also discuss how we are solving the problems of tomorrow – making AI smarter, faster and more intuitive with... Read More

BlazingDB has spent the past six months working on an open-source project (libgdf) alongside Anaconda and Nvidia. Libgdf is a library of computational primitives on top of a memory layout which is similar to Apache Arrow but optimized for GPUs. We have created a distributed, GPU-accelerated ETL pipeline that takes a user from reading data in Parquet, to performing SQL... Read More
