Problems solved by technology

However, the design of the existing distributed file system is mainly aimed at the reading and writing of large files. The storage of a large number of small files will reduce the overall performance of the file system, and cannot be well applied in systems that mainly store small files such as medical retrieval.
Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed

Abstract

The invention provides a big data access method used for accessing file resources in a cloud storage platform. The big data access method comprises the following steps: combining files of which the sizes are smaller than preset sizes in a distributed file system to form a new storage file; establishing a primary index and a secondary index for the combined file; buffering the indexes before a user requests by utilizing a pre-access mechanism. According to the big data access method, the response speed of a cloud storage platform and the overall performance of the distributed file system are kept under the condition that a great number of small files are read and written.

Description

technical field [0001] The invention relates to data storage, in particular to a large data file access method. Background technique [0002] With the rapid development of smart medical care and the emergence of massive medical data, corresponding large databases are needed as carriers to store these data, but the scheduling of big data has become a big problem. The number of documents retrieved in the medical field has also increased exponentially with network resources, especially the update speed and accumulation of small files have continued to increase, which has become an urgent problem to be solved in medical cloud storage. Although distributed file systems have been widely used in the storage and analysis of large-scale data, many organizations have adopted distributed file systems to solve the problem of rapidly growing data. However, the design of the existing distributed file system is mainly aimed at reading and writing large files, and the storage of a large nu...
