I'm working in a project that uses a mobile app with data that must be sinchronized with a database in SS (few dataobjects).

In my mobile app, data records use globally unique identifiers as Ids, so i need to define dataobjects in SS also with guids. Can we change SS dataobject behaviour to use guids instead of integers as ID fields? What's the best field type in SS to store guids?

Has anyone used this datafields that would like to share some experience?

Replacing the primary ID in DataObject is likely to be very hard and messy in core. You're best to store the GUID as a new column and simply writing your queries to use that rather than ID field (you can populate the GUID using onBeforeWrite()).
