Luca (or someone from ODB)--can you provide some additional details on this? If it's in the documentation, I can't find it, and I think these are important things to know:
1. How does OVERSIZE relate to the cluster parameter RECORD_GROW_FACTOR? 2. What is actually stored on disk when a new record is written (per-record and per-property)? 3. What overhead is incurred by storing a dynamic non-schema-defined property (i.e. how is the name of the property stored)? 4. Does it incur any per-record overhead to define a non-mandatory property in the schema if that property has not been assigned a value?
