Subject Australian JUG Presentation about Derby
Date Tue, 02 Sep 2008 06:26:39 GMT
Hi All,

I recently did a presentation about Apache Derby at the Australian Java 
User's Group meeting in Melbourne.  The presentation was titled "Using 
Apache Derby in the real world".  Its focus was not so much on how to 
use Derby, but were it can be used and how it stands up in real world 
applications.  We use Derby in our print accounting application called 
PaperCut, and feel that it's one of the "gems" of the Java community.  
Even thought we offer a choice of MS SQL Server, Oracle and Postgres 
within PaperCut, we find that 90% of our 10,000+ users stick with Derby 
- the default embedded option.  The presentation highlighted this as 
well as gave an overview of the idiosyncrasies and system performance 
tweaks we've made over the years.

I thought I'd shared the presentation with the list as some of the 
content might be useful if others want to present Derby at their local JUG!



The presentation also proposes a few potential ideas for future 
features.  That is, moving more towards zero administration, and a 
better out-of-the-box experience for all application domains.

We think Derby's best "feature" is it's wide domain of applicability - 
that is it can be used from anywhere from say a very small embedded 
database like say SQLite, all the way up to concurrent database 
applications matching MySQL, etc.  We've found that the default 
configuration options are however stacked in favor of the "small 
embedded" use case, and some manual performance tuning is required to 
get performance up on large datasets and more complex queries.  It would 
be great if the out-of-the-box domain of applicability was as wide as 
possible and one idea presented to achieve this is the concept of 
profiles.  For example, a profile parameter could be added to the 
current JDBC connection string and this could be used to reconfigure 
defaults more appropriate for the usage domain.

Hope the Derby enthusiasts find this information useful.

Kind Regards,
