Speedo TODO List

  1. Update the JDO Javadoc
  2. document the JMX console use
  3. Horizontal and Vertical mapping for the inheritance
  4. JDO 2: use standard mapping
  5. JDO 2: queries
  6. JDO 2: uses cases
  7. JDO 2: persitant interfaces
  8. JDO 2: indexes generation
  9. Avoid extent if all classes instances are loaded.
  10. Add foreign key constraint declaration and index declaration in Speedo and JORM.
  11. Bug to fix: The persistency by attachement must be checked at commit time too and can be able to forget attached instances which are no more attached to a persistent instance. That implies to maintain in the working a list of really persistent class and a list of persistent class by attadchement. At the commit time Speedo must checks if among the persistent class by attachement, some instances are no more attached to a real persistent class.
  12. Provide particular implementation of Collection and Set in order to avoid the loading in case of very large collection. These implementations would implement the collection/set methods with SQL order (add ==> INSERT, remove ==> DELETE, contains ==> SELECT, iterator ==> query, ...). The implementation idea is to consider collection elements like persistent objects. The identifier would be composed of the collection identifier and the element identifier (PName or primitive value).
  13. Attribute a weight to the compiled query. This weight would be based on the time to compile the query. Indeed an heavy query should be kept in cache in place of light weight query.
  14. Distributed concurrency manager (use existing Perseus component)
  15. Distributed cache
  16. When prefetching an extent of an inheritance graph, with auto references, avoid to load these auto references form the database if already present in the prefetch buffer (but not yet in the map [PName -> RowId]).
  17. Administration via JMX using Fractal
  18. Allow to have 2 java fields with the same name into 2 classes belonging to the same inheritance graph (see JORM bug).
  19. Hide persistent object distribution (in several database)
  20. Speedo over file system
  21. Separate the enhancer in two parts: class weaving and mapping code generation
  22. Currently, to get a sequence, one class of the package must be loaded before the pm.getSequence.
  23. For jdo2 sequence, factory class and contiguous.
