CloudKit是强烈一致的,还是最终一致的？

官方文档是否在某处讨论有关CloudKit的一致性？根据我的测试,它似乎最终是一致的 - 在写完之后立即读取记录可能有用而且可能不会(返回空结果):

CKDatabase *database = [[CKContainer defaultContainer] publicCloudDatabase];
CKRecord *record = [[CKRecord alloc] initWithRecordType:@"Foo"];

dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
[database saveRecord:record completionHandler:^(CKRecord *record, NSError *error) {
    CKQuery *query = [[CKQuery alloc] initWithRecordType:@"Foo" predicate:[NSPredicate predicateWithFormat:@"TRUEPREDICATE"]];
    [database performQuery:query inZoneWithID:nil completionHandler:^(NSArray *results, NSError *error) {
        XCTAssertEqualObjects(results, @[], @"Freshly written object not returned by query."); // succeeds
        dispatch_semaphore_signal(semaphore);
    }];
}];

dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);

有没有办法强制强烈一致的读取,以反映所有以前的更新？
