As Swift is extremely dynamic and flexible, it needs to be tested under various load scenarios to monitor its performance. It is very challenging to evaluate its performance under various workloads. To address this problem we are building up a solution which benchmark the object store with ...
会出现警告:Cannot override a non-dynamic class declaration from an extension。 出现这个问题的原因是,NSObject的extension是使用的Message dispatch,而Initial Declaration使用的是Table dispath(查看上图 Swift Dispatch Method)。extension重载的方法添加在了Message dispatch内,没有修改虚函数表,虚函数表内还是父类的...
Storage policy: Storage Policies provide a way for object storage providers to differentiate service levels, features and behaviors of a Swift deployment. Each Storage Policy configured in Swift is exposed to the client via an abstract name. Each device in the system is assigned to one or more ...
OpenStack Object Storage (Swift) 是用来创建冗余的、可扩展的对象存储(引擎)的开源软件。通过阅读Swift的技术文档,我们可以理解其中的设计的原理和实现的方法。 Swift项目已经进展有两年了,对外开放也一年有余,在国外的社区你可以获得许多帮助,但在国内只能找到一些零零散散不齐全的资料,许多人更喜欢坐享其成,而不...

这里用到了一个技术叫做Indirect Storage With Copy-On-Write,即优先使用内存指针。通过提高内存指针的使用,来降低堆区内存的初始化。降低内存消耗。在需要修改值的时候,会先检测引用计数检测,如果有大于1的引用计数,则开辟新内存,创建新的实例。在对内容进行变更的时候,会开启一块新的内存,伪代码如下: ...
swift-object-auditor 会打开一个对象服务器上的所有对象,确保它们的元数据是正确的,而且有有合适的大小和 MD5 它们都必须在各自对应的服务的配置文件中的 [account/object/container-auditor] 部分做相应配置,然后它们就会定期运行,并输出日志。 2.2 集群监控状态获取工具 swift-dispersion-populate 和 swift-dispersion...

 如果在开发过程中,错误的混合了这几种分派方式,就可能出现Bug,以下我们对这些Bug进行分析: SR-584 此情况是在子类的extension中重载父类方法时,出现和预期不同的行为。
這裡用到了一個技術叫做Indirect Storage With Copy-On-Write,即優先使用記憶體指標。透過提高記憶體指標的使用,來降低堆區記憶體的初始化。降低記憶體消耗。在需要修改值的時候,會先檢測引用計數檢測,如果有大於1的引用計數,則開闢新記憶體,建立新的例項。在對內容進行變更的時候,會開啟一塊新的記憶體,虛擬碼如...
