FIVE PERFORMANCE ENHANCEMENTS FOR HYBRID HASH JOIN

                 Goetz Graefe
             University of Colorado

Abstract

Novel database applications demand not only high functionality but also
high performance.  To satisfy these two requirements, the Volcano
project investigates efficient, extensible tools for query and request
processing in novel application domains, particularly in
object-oriented and scientific database systems.  One of the specific
goals is to explore algorithms that are useful for query processing in
a variety of data models and to design and validate performance
enhancements of such algorithms.

This talk focuses on set matching algorithms such as intersection,
difference, union, and relational join, using join as a representative
for all these matching problems.  I shall discuss five performance
enhancements for hybrid hash join algorithms, namely data compression,
large cluster sizes and multi-level recursion, role reversal, histogram
methods to exploit non-uniform data and hash value distributions
(skew), and join algorithms for multiple inputs.  The most surprising
result is that hash value skew can be exploited and improve performance
rather than being a danger to hybrid hash join performance as
conventionally thought.  The design for hash-based N-way matching
algorithms is a dual to pipelining data without intermediate sort
between multiple merge-joins on the same attribute (interesting
orderings), and exceeds its performance advantages.

Each of the performance enhancements can be used by itself or they can
be combined with each other as well as with parallel query execution
techniques.  The cumulative effect of the optimizations is that hybrid
hash join will almost always be the set matching algorithm of choice,
even in situations for which earlier research had recommended sorting
and merge-join.

Biography

Goetz Graefe received his M.S. and Ph.D. degrees in computer science in
1984 and 1987 at the University of Wisconsin-Madison.  His thesis work
was the EXODUS Optimizer Generator.  In 1987, he joined the faculty of
the Oregon Graduate Institute where he initiated both the Volcano
project on extensible query processing and, with David Maier, the
Revelation project on object-oriented query processing and
performance.  Since 1989, he has been an Assistant Professor in
Computer Science at the University of Colorado at Boulder.  He is
currently working on extensions to Volcano including a new optimizer
generator, request processing in object-oriented and scientific
database systems, optimization and execution of very complex queries,
and physical database design.
