This got me thinking about DataRow memory/creation efficiency throughout the framework. We are wasting lots of space on repeating information. Essentially a DataRow for each entity has a well defined set of keys, so ideally we can normalize the storage of DataRows internally, saving an Object[] of values with a reference to a shared "decode map", one per entity. Such a shared map would have DbAttribute names for the keys and array positions for the values. What we'll lose is the ability to serialize DataRows (e.g. for remote notifications), but maybe we can work around it somehow.
Just thinking out loud ... Andrus
