We invite you to participate in the db4o performance contest which will give away 6000 USD in prizes!

Basically participants will provide patches to the db4o core that impact on performance and then these modifications will be judged by the community to select the winners. In order to make the whole process easier we're providing the following:

Ideas for possible improvements are:

  • A UTF-8 String encoder
  • Improvements to the query processor
    • Removal of processed index constraints from the processor so they won't run in the SODA processor
    • Class index filtering of the index results to be able to ignore the SODA processor run completely if all constraints are processed
    • Index processing of ANDs and ORs over field constraints at difference hierarchy levels
  • Improving the BTree implementation
    • MRU cache for BTree pages 

The Performance Costest has started already and it ends on August 15 2008.

Please hurry and submit your patch! =)
