PDL Visit Day 2019: Aurosish Mishra (Oracle)

Oracle Autonomous Database is the industry's first self-driving, self-securing and self-repairing cloud database. It combines decades of database automation techniques and database infrastructure development, with the power of machine learning to deliver a fully autonomous database that revolutionizes data management, enabling enterprises to evolve from the role of builders and managers of databases to users of autonomous database cloud services that offer self-driving capabilities - for any workload! In this talk, we will peek under the hood of the Oracle Read More

Master Thesis Talk: Supporting Hybrid Workloads for In-Memory Database Management Systems via a Universal Columnar Storage Format

The proliferation of modern data processing ecosystems has given rise to open-source columnar data formats. The key advantage of these formats is that they allow organizations to load data from database management systems (DBMSs) once instead of having to convert it to a new format for each usage. These formats, however, are read-only. This means that organizations must still use a heavy-weight transformation process to load data from their original format into the desired columnar format. We aim to reduce Read More

Master Thesis Talk: Non-blocking Lazy Schema Changes in Multi-version Database Management Systems

The relational schema of a table in a database management system (DBMS) describes its logical attribute information and constraints. Despite the aim of separation between logical schema and physical data storage, in practice, the schema often dictates how a DBMS organizes data on disk or in memory. This tight coupling is because the database's physical schema must match its logical schema. The problem with this is that applications that incur frequent schema changes (e.g., add a column, change column type) Read More

Joy Arulraj Wins SIGMOD Jim Gray Dissertation Award

Pittsburgh, PA — The Carnegie Mellon Database Group is pleased to announce that CS alumnus Prof. Joy Arulraj (now faculty at the Georgia Institute of Technology) has won the 2019 ACM SIGMOD Jim Gray Dissertation Award. This honor is conferred for the best dissertation in the field of databases for the previous year. Joy's thesis, entitled "The Design and Implementation of a Non-Volatile Memory Database Management Systems", is based on his work exploring new DBMS architectures for NVM. This was Read More

Spring 2019: Ippokratis Pandis (PhD’07, Amazon)

Amazon Redshift is a fast, fully managed, large-scale data warehouse solution that makes it simple and cost-effective to efficiently analyze large volumes of data using existing business intelligence tools. In this talk we are going to dive into Redshift's architecture and talk about how we leverage fleet telemetry in order to prioritize the whole development process and to make Redshift achieve top of the line performance at any data scale and concurrency. For that, we are going to focus on Read More

Spring 2019: Anil Goel (SAP)

SAP's HANA data management platform was architected from the ground up to leverage modern hardware technologies including large main memories, multi-core parallelism, SIMD architectures and vector processing, and to exploit software-hardware co-innovation. SAP HANA supports novel and existing applications with dramatically faster queries, access to up-to-date business data, and greatly simplified database administration. In this talk, we'll describe some key aspects of the internal design of the HANA system, explaining how HANA achieves orders of magnitude performance improvements. We will Read More

Prof. Andy Pavlo wins 2019 NSF CAREER Award

Pittsburgh, Pennsylvania — Complacency is our biggest enemy. It lulls the mind into laziness. It makes us not question how things should be because we take for granted that this how things have always been done. This is especially true in databases where the market is established and well-endowed incumbents are entrenched. Thus, it takes resolution and pluck to challenge this world and strive for something better. With this in mind, the CMU Database Group is pleased to announce that Read More
