Abstract: A storage layer may be configured to over-provision logical storage resources to objects. The storage layer may provision the resources in response to, inter alia, a request to open and/or create a zero-length file. The storage layer may be further configured to store data of the objects in a contextual format configured to associate the data with respective logical identifiers. The storage layer may determine an actual, storage size of the object based on the associations stored on the stored associations. Storage clients may rely on the storage layer to determine the size of the object and, as such, may defer and/or eliminate updates to persistent metadata.

Abstract translation: 可以将存储层配置为向对象过度提供逻辑存储资源。 尤其是响应于打开和/或创建零长度文件的请求，存储层可以提供资源。 存储层可以被进一步配置为以配置成将数据与相应的逻辑标识符相关联的上下文格式来存储对象的数据。 存储层可以基于存储在所存储的关联上的关联来确定对象的实际存储大小。 存储客户端可以依靠存储层来确定对象的大小，并且因此可以延迟和/或消除对持久性元数据的更新。
