Realm文件从KB到MB

Question

我有一个50k文件的列表，我需要将它保存到领域。

我以下面的方式保存。在此操作之前，域文件是40KB。在此之后它增加到200 MB。你能告诉我一个最好的方法或我的代码有什么问题。我创建了一个保存领域文件列表的函数。

func saveList<T: Object>(_ list: List<T>?) {
        autoreleasepool {
            if let list = list {
                let backgroundQueue = DispatchQueue(label: "realm", qos: .background, attributes: [], autoreleaseFrequency: .workItem, target: nil)
                var defaultRealm: Realm?
                backgroundQueue.sync {
                    autoreleasepool {
                    do {
                        defaultRealm = try Realm(configuration: Realm.Configuration(fileURL:URL(path)))
                    } catch let error {
                        debugPrint("Realm Can't be created on  thread \(Thread.current) and error is \(error.localizedDescription)")
                    }
                    if let realm = defaultRealm {
                        defer {
                            debugPrint("All Saving done. - May be success or failure")
                        }
                        do {
                            try realm.write {
                                for realmObject in list {
                                    autoreleasepool{
                                        realm.add(realmObject, update: true)
                                    }
                                }
                            }
                        } catch let error {
                            debugPrint(" Can't add Realm Object on thread \(Thread.current) thread and error is \(error.localizedDescription)")
                        }
                    }
                    }
                }
            }
        }
    }

请告诉我这是否有任何问题。
