Automatic Database Management System Tuning Through Large-scale Machine Learning

Friday, December 1st, 2017 from 12-1 pm in GHC 6501.

Dana Van Aken, CSD

Database management systems (DBMSs) are the most important component of any data-intensive application. They can handle large amounts of data and complex workloads. But they're difficult to manage because they have hundreds of configuration ``knobs'' that control factors such as the amount of memory to use for caches and how often to write data to storage. Organizations often hire experts to help with tuning activities, but experts are prohibitively expensive for many.

In this talk, I will present OtterTune, a new tool that can automatically find good settings for a DBMS's configuration knobs. OtterTune differs from other DBMS configuration tools because it leverages knowledge gained from tuning previous DBMS deployments to tune new ones. Our evaluation shows that OtterTune recommends configurations that are as good as or better than ones generated by existing tools or a human expert.

General Info

The Student Seminar Series is an informal research seminar by and for SCS graduate students from noon to 1 pm on Tuesdays and Fridays. Lunch is provided by the Computer Science Department (personal thanks to Sharon Burks and Debbie Cavlovich!). At each meeting, a different student speaker will give an informal, 40-minute talk about his/her research, followed by questions/suggestions/brainstorming. We try to attract people with a diverse set of interests, and encourage speakers to present at a very general, accessible level.

So why are we doing this and why take part? In the best case scenario, this will lead to some interesting cross-disciplinary work among people in different fields and people may get some new ideas about their research. In the worst case scenario, a few people will practice their public speaking and the rest get together for a free lunch.

Guideline & Speaking Requirement Need-to-Know

Note: Step #1 below are applicable to all SSS speakers. You can schedule AT MOST THREE talks per semester.

SSS is an ideal forum for SCS students to give presentations that count toward fulfilling their speaking requirements. The specifics, though, vary with each department. For instance, students in CSD will need to be familiar with the notes in Section 8 of the Ph.D. document and follow the instructions outlined on the Speakers Club homepage. Roughly speaking, these are the steps:

  1. Schedule a talk with SSS by sending your talk title, abstract, additional info (like "Joint work with..." or "In Partial Fulfillment of the Speaking Requirement"), and a picture of yourself (preferably jpeg) to sss@cs at least TWO WEEKS before your scheduled talk.
  2. After you are confirmed with your SSS slot, go to the Speakers Club Calendar and schedule your talk at least THREE WEEKS in advance of the talk date.
  3. On the day of your talk, make sure you print Speakers Club evaluation forms for your evaluators to use.
Students outside of CSD will need to check with their respective departments regarding the procedure. As another example, ISRI students fulfill their speaking requirements by attending a semesterly Software Research Seminar and giving X number of presentations per school year. If you have experience with your department that might help others in your department, please feel free to contribute your knowledge by emailing us. Thank you!
