Title: Hyder: A Transactional Indexed Record Manager for Shared Flash Storage

When: 3:00 PM to 4:00 PM (Wednesday, November 25th, 2009)

Abstract:

An enormous increase in the I/O rate to shared storage is made possible by the availability of large flash storage chips and cheap high-speed network switches. Hyder is a research project to develop a new transactional indexed-record manager based on these technologies. It's a data-sharing system, where all compute servers have direct access to shared flash storage and no direct-attached disk. Its main feature is that it scales out without partitioning the database or application. It is therefore well-suited to a data center environment, where scale-out is especially important and where specialized flash hardware and networking can be cost- effective. The software architecture that makes this possible is radically different than classical transactional record managers. It uses log-structured record storage, sliding-window RAID, binary search trees, and optimistic concurrency control. There is no locking, ARIES-style logging, or B-trees. After a brief discussion of motivation, I will spend most of the talk describing the architecture. This work is joint with Colin Reid, also at Microsoft.
