The grad students at UCB hold a DBlunch session periodically
through out the school year.  The talks, obviously, are not
postgres specific but about specific databases topics.

I have not attended any yet. I am not sure if
they are officially open to the public, but I am on the
list and I doubt if anyone would be thrown out.

If anyone is interested in going with me, let me know.
I am more likely to attend if I have company.

Hello all,

Starting this semester DBLunch will be held in conjuction with Intel
Research Berkeley seminar. The Intel lab in Downtown Berkeley on the
Penthouse floor of the PowerBar building (see for more location
details). The new time is Thursdays 3:30-5:00PM.

The first seminar will be next week

Cache Tables:  Paving the way for an Adaptive Database Cache
Hehmet Altinel
IBM Almaden Research Center

Thursday, Sep 25, 2003
15:30 - 17:00 Pacific Time
Intel Research Berkeley, 2150 Shattuck Ave., Suite 1300

In this talk I will present a new database object called Cache Table that
enables persistent caching of the full or partial content of a remote
database table. The content of a cache table is either defined declaratively
and populated in advance at setup time, or determined dynamically and
populated on demand at query execution time.

Dynamic cache tables exploit the characteristics of typical transactional
web applications with a high volume of short transactions, simple equality
predicates, and 3-4 way joins.

Based on federated query processing capabilities, we developed a set of new
technologies for database caching: cache tables, "Janus" (two-headed) query
execution plans, cache constraints, and asynchronous cache population

Our solution supports transparent caching both at the edge of
content-delivery networks and in the middle-tier of an enterprise
application infrastructure, improving the response time, throughput and
scalability of transactional web applications.

If time permits, the talk will also include a demo of the system.

Mehmet Altinel received his M.S. and Ph.D. degrees in Computer Engineering
from Middle East Technical University, Ankara, Turkey in 1994 and 2000
respectively. He is currently working as Advisory Software Engineer at IBM
Almaden Research Center. His research interests include databases, data
management issues in middleware systems, dissemination and broadcast, and
data management on the Internet.
