Problems solved by technology

Faced with a wide variety of file systems, it is impossible to access them in a unified way. Users must learn how to use different file systems, and the learning cost is quite high.
When using data, there are often situations where data is read across multiple data centers. Limited by dedicated line bandwidth and network stability, user experience is often extremely poor

Abstract

The invention provides a cross-data-center data storage and query method and system, and the method comprises the steps: receiving a file query request, checking whether a second data center caches a queried file, and storing the file in a first data center; for the situation that the second data center caches the file, verifying the consistency of the file stored in the main file system of the first data center and the file stored in the cache file system of the second data center; if the consistency check is passed, directly returning the file; if the consistency check is not passed or the file is not queried, generating a cache task, and submitting the cache task to a task queue of a second data center; after the task queue receives the cache task, arranging the cache task to run according to the queuing condition in the queue; and after the operation of the cache task is completed, returning the file in the cache file system.

Description

Technical field [0001] The present disclosure relates to data storage, data query, reading technology, and more particularly to data storage and query methods, systems, electronic devices, and computer readable storage media across data centers. Background technique [0002] Data is the most important property, data storage and use of the big data era, and is also the most important issue facing major companies. In the face of the storage of data on TB or even PB, major companies have their own solutions, such as Amazon's S3 storage system, Google's GFS, open source community HDFS, and object storage of major cloud manufacturers. In the face of a wide variety of file systems, it is unable to access a unified approach. Users must learn their way of use for different file systems. The learning cost is quite high. When the data is used, there is often a case where data is read across multiple data centers, which is limited to special line bandwidth and network stability, and the use...
