Title: Learning in Query Optimization
Speaker: Volker Markl, IBM Almaden Research Center
Speaker Bio: http://www.almaden.ibm.com/cs/people/marklv/
Abstract
Database Systems let users specify queries in a declarative language
like SQL. Most modern DBMS optimizers rely upon a cost model to choose
the best query execution plan (QEP) for any given query. Cost estimates
are heavily dependent upon the optimizer's estimates for the number
of rows that will result at each step of the QEP for complex
queries involving many predicates and/or operations. These estimates,
in turn, rely upon statistics on the database and modeling assumptions
that may or may not be true for a given database. In the first part
of our talk, we present research on learning in query optimization
that we have carried out at the IBM Almaden Research Center. We
introduce LEO, DB2's LEarning Optimizer, as a comprehensive way to
repair incorrect statistics and cardinality estimates of a query
execution plan. By monitoring executed queries, LEO compares the
optimizer's estimates with actuals at each step in a QEP, and computes
adjustments to cost estimates and statistics that may be used during the
current and future query optimizations. LEO introduces a feedback loop
to query optimization that enhances the available information on the
database where the most queries have occurred, allowing the optimizer
to actually learn from its past mistakes.
In the second part of the talk, we describe how the knowledge gleaned by
LEO is exploited consistently in a query optimizer, by adjusting the
optimizer's model and by maximzing information entropy.

APWeb and WAIM are two leading international conferences on research,
development and applications of Web technologies, database systems,
information management and software engineering, with a focus on the
Asia-Pacific region. Previous APWeb conferences were held in Beijing
(1998), Hong Kong (1999), Xian (2000), Changsha (2001), Xian (2003),
Hangzhou (2004), Shanghai (2005), and Harbin (2006); and previous WAIM

In collaboration with ACM SIGMOD and the Database Society of China
(DBSC), APWeb and WAIM will have a joint conference in 2007. This
will be an associated conference of ACM SIGMOD/PODS 2007 (in Beijing,
China), officially endorsed by SIGMOD and DBSC. APWeb/WAIM 2007 will
be held two days after SIGMOD/PODS 2007, in the beautiful mountain
area of Huang Shan (Yellow Mountains) -- the only dual World Heritage
listed area in China for its astonishing natural beauty, and rich and
well preserved culture.
APWeb/WAIM 2007 will combine and enhance the traditions and the
research topics of interest to the APWeb and WAIM communities.
