The way that I did before was, creating my own local database, en then
when there was a change, replicate the changed data, using DO, to the
server.
But then I have to keep things in memory.
I was hoping for new ideas or that In the Snow version was something
new.
I guess the way to go is, use a local SQL store with CoreData, and
replicate the changed data from local to the server using DO.
The server will also have coredata using SQL.
People have done that.
But what should I do?
1. The server should have multiply network entries/connections, but
only one entry to the coredata > SQL
This is a lot simpler, and probably what you want to start with.
2. The server should have multiply network entries/connections, and
equal multiply entries to the coredata > SQL <- will coredata keep the
data uptodate from different read/write requests ( entries) of the
same data? If f.e one connection do a request for data A and change
something of data A, that a second connection who want also read Data
A get the update data?
On 10.5 that's possible, but tricky. It requires attention to a lot
of details, like staleness intervals, merge policies, and refreshing
objects.
