Embodiment Construction

[0043] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0044] see figure 1 , which shows a system for parallel access to a large number of small files in cluster storage according to an embodiment of the present invention, including application host clusters, metadata server clusters, data server clusters, back-end storage and high-speed interconnection devices, wherein:

[0045] The application host cluster is used to provide a file system interface for the client. When a small file is detected to be written, the small file is cached, and multiple cached small files are merged into a temporary file. The metadata and data objects are pushed to each metadata server node and each data server node in the cluster through the high-speed interconnection device.

[0046] The metadata server cluster is used to manage the backend storage of each metadata server node in the cluster.

[0047] The data server cluste...

Abstract

The invention provides a method and system concurrently accessing a large amount of small documents in cluster storage. The method comprises the following steps: the written small documents are buffered, a plurality of buffered small documents are merged into one temporary document, the metadata and the data object of the temporary document are stored into the backend storage of a metadata server node and a data server node. The method can effectively improve the response time and speed of the cluster document system service and the whole data read and write time and transaction capacity per unit time of the data.

Description

technical field [0001] The invention relates to a method and system for parallel accessing a large number of small files in cluster storage, which is usually used in large-scale mass data storage and read-write applications. Background technique [0002] With the continuous development of network applications and e-commerce in finance, petroleum, telecommunications, production, etc., the number of visits to various sites is increasing, and the scale of data is also continuously expanding. File access, especially a large number of small files in network applications The performance problems of parallel access to files are becoming more and more prominent, such as processing user orders too slowly, and a series of problems such as image display lag, which will seriously affect the normal use of users. [0003] Common enterprise data applications are built on disk arrays. Therefore, how to provide a method for organizing and accessing these data so that they can be applied in t...
