This fork contains the following improvements
- Better handling of ordered edges
- Support for LoadRecord and CreateRecord operations - faster than performing the same action via SQL commands
- Improved mapping code for generic types to/from ODocuments - much faster, avoids repeated reflection
- Support for fetch plans using LoadRecord to pull back a whole tree of objects in one request
- Initial support for transactional create/update/delete - should be much faster than multiple individual SQL commands
- Better support for derived types - .ToUnique will construct a TDerived if the database record is of type TDerived
Fetching a large block of records from the DB via Database.Load.ORID(orid).FetchPlan(plan) and converting them to typed objects about 6 times faster than original code using SQL commands and old mapping
