For most of next week, I'll be either at CommunityOne or JavaOne.
Kristian Waagan (of Sun's Java DB development team) has really given Java DB (Sun's distribution of Apache / Derby) a new life of its own when it comes to handling CLOBs, starting with Java DB 10.5. Check out this thread.  Note the following testimony from David Goulden: The performance improvements with CLOBs are dramatic. I created a record with a CLOB containing about 10 million...
According to a ChemAxon's forum posting from earlier last year, ChemAxon's Instant JChem has already been using Java DB (Apache Derby) in favor of HSQL for some time now! The authors who praise Derby also express a wish for in-memory storage, which is now part of Derby 10.5 and will soon appear in Java DB 10.5 for distribution with the JDK. (Unfortunately, some of the other posts on the forum...
Mike Haller has put together a Twitter desktop client using Derby for local data. Haller should probably also try this on the CDC environment. This would be a coll application for the CDC devices! Apache / Derby is the cauldron in which Java DB is forged and made ready by Sun's Java DB team as well as other members of the Apache Derby community. Sun Java DB engineers will soon be releasing...
Here, I usually write about Java-related issues, like my recent posts about Java DB. However, every once in a while I point to something outside of Java, usually turning focus on some other communities and projects managed by Sun. When this happens, I usually write on my Blogs.Sun.Com (BSC) blog, and put a pointer here. So, as an example, most recently I have posted a brief note about some...
On this MacBook Pro laptop I'm currently using (2.5 GHz, intel Core 2 Duo, 4GB 667 MHz DDR2 SDRAM, Mac OS-X 10.5.6), with lots of other apps running, it took exactly 43 seconds to build the Apache Derby database. Apache Derby is the cauldron where Sun and other Apache participants forge what later becomes "Java DB" a database shipped with every copy of the JDK! It was amazing that unlike years...
Now, a new release of Apache/Derby is out. Francois Orsini has a more detailed note on this. It is great to see that many of the features listed are developed by our small but amazing team of Java DB engineers. (See my previous release about this cauldron where Java DB is forged!)
