Research direction
Start with the reflection-based EntityPropertiesMapper and determine the scope of the proposed compile-time source generator and IEntitySerializable interface. Done should include a source-generated serialization path that avoids reflection and establishes whether nested complex-type properties can be persisted in primitive columns.
Written by the indexing model from the issue text.
Description
Right now we have a reflection-based EntityPropertiesMapper, that only supports primitive types (or fails at run-time).
We could use a compile-time source generator (no need to actually emit anything for intellisense, since this is all for run-time) that implements an interface (i.e. IEntitySerializable) so that the mapper can check if the entity to convert supports this mechanism and avoid any reflection altogether.
This could also be the foundation for arbitrary object graphs to be persisted in primitive columns too, in particular for complex-type record properties that improve API design like structured Address and the like. So perhaps not lists and collections, but nested properties only?
