Problems solved by technology

[0011] An object of the present invention is to provide a method and system for metadata interaction, which can solve the problem that the back-end machine is under too much pressure, and the resource space written by each user cannot be assigned a Quota quota, and the data between users cannot be obtained. Partition and isolation, and security cannot be guaranteed

Embodiment Construction

[0099] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0100] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0101] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0102] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static rando...

Abstract

The purpose of the invention is to provide a metadata interaction method and system. By adoption of the metadata interaction method and system provided by the invention, a back end consistency total system is formed by a plurality of back end machines, the back end machines are divided into multiple subareas, the subareas respectively respond to corresponding requests, thereby sharing the requestpressure and avoiding the problem of overlarge pressure resulting from that the same back end machine responds to all requests, the horizontal expansion of the back end machines is achieved, in addition, by allocating the corresponding subareas to different users, Quota can be performed on the metadata resource space written by each user, and the partition and isolation of the metadata between theusers are achieved, the security is ensured, and different users can be conveniently distinguished to perform Quota charging.

Description

technical field [0001] The invention relates to the field of computers, in particular to a metadata interaction method and system. Background technique [0002] Nowadays, the data storage of more and more businesses needs to break through the boundary of the data center to realize the ability of cross-regional services. Asynchronous data replication based on cross-regions seems to be able to solve this problem. However, in fact, this kind of asynchronous replication will make it difficult to achieve data consistency, and even fail to handle disaster recovery at the regional level. In some industries that require extremely high data consistency and reliability, such as Internet finance, this kind of asynchronous replication is completely inadequate. [0003] Therefore, when designing a cross-regional consistency metadata storage system (Global Meta System) solution, the back-end system will always be inseparable from the use of a distributed consistency system (Quorum) to so...
