We are looking into the network traffic between the Derby JDBC driver
and the Network server and have compared this against MySQL and
PostgreSQL. The main finding is that Derby sends more messages than
the two other databases.

DerbyJUnitTest has many cases where the SQLException thrown by Derby
(through JDBC) is ignored. To me, this seems very bad practice for test
code.
For example:

BayLISA (www.baylisa.org) would like someone to give a 90 minute talk

Push join predicates into union and other set operations. DERBY-649 implemented
scalar (single table) predicate pushdown. Adding join predicate push down could
improve performance significantly.
I could do this, depending on the timing. I think it would make sense
to talk about Derby in general but focus how you can embed Derby in a
browser to give a very easy distribution model for database
applications, allowing users to keep private data on their machine while
running a web app,
I think this would be great! I'd like to attend.

Hi David,
I could help, if needed. I presented a talk about developing
applications on Derby at DB2 information management conference sometime
ago and have foils for that. We could expand that presentation to
include parts of Jean's presentation/tutorial to cover the introduction

Hi, Dan. This looks very appealing. The one area I'm a little
uncertain about is with the messages that are common across client and
