解析本地数据存储区：管理脏的固定对象

Question

How can one track whose Parse Local Datastore pinned objects were changed so that only those objects are synched with the server? Is it safe/enough to label pinned objects as dirty and only synch those to the server? Or does saveEventually handles this automatically, ie, it only synchs dirty objects to the server and therefore the labelling of those pinned objects is redundant?

Thanks!

Answer 1

Jorge, The simple answer is saveEventually will handle saving the changed object to the local datastore and will also save to the Parse server as well when a connection becomes available.

Here is what the Parse Android guide has to say: The advantage is that if the user currently doesn't have a network connection, saveEventually will store the update on the device until a network connection is re-established. If your app is closed before the connection is back, Parse will try again the next time the app is opened.
