Basser Seminar Talk by David Lomet

April 27th, 2009

There is an interesting talk in the Basser seminar on Monday, 27 April, 5pm, by David Lomet from Microsoft Research:

Immortal DB: A Compelling Case for Transaction Time Database Systems

Speaker: Dr David Lomet (Principal Researcher, Microsoft Research)
Time: Monday 27 April 2009, 5:00-6:00pm
Location: SIT Lecture Theatre (Room 123), Level 1

ABSTRACT
Immortal DB is a transaction time database that is built into the kernel of a commercial database system, Microsoft SQL Server. The Immortal DB goal was to have performance comparable to that of an unversioned current time database, while providing the benefit of being able to access all historical database states with good performance. This ability to access historical database states is an important part of audit functionality, which Immortal DB supplements by being able to identify the user responsible for each transaction. Immortal DB versioning is a high performance implementation of snapshot isolation versioning as well. Further, Immortal DB supports high availability via fast removal of the effects of bad user transactions, which lead to long outages with conventional techniques. The combination of excellent performance with audit and high availability functionality is unique to Immortal DB.
