how to data synchronization? #259
Description
synchronized (NoteModel.class) {
boolean isExist = DBStore.getInstance().getNoteModelBox().count() != 0;
if (!isExist) {
DBStore.getInstance().getNoteModelBox().put(noteModel);
} else {
noteId = DBStore.getInstance().getNoteModeList().get(0).getNoteId();
}
}
Many times, I have some insert and update operations, however, because only the id is guaranteed to be unique. I insert, you need to determine whether it already exists, if there is updated, but found that the concurrent operation, it will lead to repeated data insertion
