Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0031] The overall idea of the present invention is that when a user logs in for the first time, after the namespace server obtains user information, it generates a user directory tree according to the global directory tree maintained by it and the metadata information of resource objects maintained by the metadata server, and returns it to the client. Obtain the user directory tree, parse the...

The invention discloses a method for obtaining metadata in a cloud storage system. The method comprises the following steps: a client side transmits login information of a user to a certificate server; the certificate server determines whether the user exists according to the login information; if the user exists, the certificate server sends the registration information to a naming space server; the naming space server obtains user information according to the login information and a directory subtree of the user in the naming space server is obtained according to the user information; organization is carried out on the user directory subtree to generate a new user directory tree, and the new user directory tree is returned to the client side; the client side determines whether the obtaining of the user directory tree is successful according to organization results; and if the obtaining of the user directory tree is successful, the naming space server transmits the user directory tree to the client side, wherein the transmission employs an xml file form. According to the invention, problems in existing methods that the speed of accessing data by users is influenced due to that the users need to give requests for the metadata to meta-data servers each time before access to data are solved.
Description
technical field [0001] The invention belongs to the field of cloud storage, and more specifically relates to a method for acquiring metadata in a cloud storage system. Background technique [0002] With the explosive growth of Internet data volume, how to efficiently, reliably and stably store these data has become very urgent, so cloud storage has also become a research hotspot in the field of network storage. In order to obtain higher system scalability and high access speed, the cloud storage system will adopt the method of separating data and metadata. Before data access, metadata will be obtained first, and data will be located according to metadata. In these storage systems, how to organize And obtaining metadata becomes particularly critical, and will become an important factor affecting the performance of cloud storage systems. [0003] A storage system that separates data from metadata often adopts a centralized metadata service model or a distributed metadata serv...
