Hello to all! What's the correct way in Core Data to save a stream of data? This is the problem. Suppose to have lots of packets each of these can be linked to a parent and could have one or more childrens. You can receive these packets ordered (so you can receive the parent of message only in a message after x (the next or after other y messages)).
The problem is to save these messages in CoreData without using lots of CPU resources and your code need to "see" newly inserted messages. I've made some tests with a a code of mine but it does not works. Anyone can tell me what's the right way? This is what I've made (suppose you receive a data from a multithreaded socket). 1) You receive the packet 2) Put it into a temp array 3) When you reach a number x of messages you can call the save function The save function repeats these statements for each packet from the array: 1) Perform insertObject in a second managedObject (connected to the same persistent store) 2) Get the list of objectID of the object and save it to another array 3) When all packets was saved perform linkMessages function into main thread passing the objectids array The LinkMessages function: 1) Perform a refreshObject: elementOfTheArray mergeChanges: YES for each object passed by the array 2) Find the parent/childs and make the right releationships 3) Perform a save operation to disk I think it could be correct but it does not work because the newly insert objects seems to be invisible into the main context. Where I'm wrong? I'm going crazy with this damn thing :( Thanks a lot for each response! _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
