Hi,
I'm working on adding uuid support as primary key with a prototype and ERRest
support. Actually, my implementation uses a 16 bytes NSData as the adaptor
value type. Before going too far in this, I would like to validate my choices...
I see 2 options:
1- A 16 bytes NSData
Pro: It seems the most efficient and adapted data type.
Cons: Hard to read and type in SQL queries. GlobalIds are cryptic.
2- A 32 char hex string (or a 36 one if pretty printed with the dashes).
Pro: Easier to read, especially with the dashes.
Cons: Uses more spaces, maybe less fast. Seems a bit awkward to deal
with hex strings.
For the ERRest part, I managed to format the uuid in a primary key by detecting
if it is a 16 bytes NSData in the formatted hex representation. I also found a
way to get objects using the hex representation.
Any though on this ? Something I missed ?
Finally, is a presentation on using uuid for primary key in next WOWODC would
be a good topic ?
