Speedo TODO List

  1. 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.
  2. Horizontal mapping for the inheritance (Olivier is working on)
    1. Medor/query must support horizontal mapping for navigation.
    2. constant hidden field
  3. Vertical mapping for the inheritance
  4. Cascade delete
  5. JDO 2: interfaces
  6. JDO 2: use standard mapping
  7. JDO 2: query result type
  8. JDO 2: SUM, MAX, AVG in queries
  9. JDO 2: distinct in queries
  10. JDO 2: queries limit
  11. JDO 2: indexes generation
  12. Generate SQL script for database initialization (table creation, foreign key constraint declaration, index declaration) TODO in JORM.
  13. 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).
  14. 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.
  15. Distributed concurrency manager (use existing Perseus component)
  16. Distributed cache
  17. 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]).
  18. Administration via JMX using Fractal
