I'm storing application preferences in the datastore, they come in a
variety of types. As I see it I've got three choices for implementation:
* Name / Blob
-- "general" has a json encoded object of all of the sub-settings
* Name / ID / Lots of Fields
-- Where ID = "general" or "user" (etc.) and different fields in
each entity
* Name / ID / Key / Value
-- Where you query out all of the "user" settings and
re-construct an object from it.
My gut feel is that #2 is preferable, since it avoids double encoding
the data and doing a query out of a large number of records in the later
case.
Thanks,
