Problems solved by technology

[0004] In Hadoop, in order to achieve high availability of cluster storage, Hadoop’s HDFS file storage system provides two storage methods: Block replication (that is, multiple copies of file blocks) and Erasure coding (that is, erasure coding technology), but the storage method of Block replication is in While improving data availability, it also causes 200% additional overhead of storage space, and additional bandwidth consumption when writing data; while Erasure coding storage method is better than Blockreplication storage method in terms of storage space usage and data writing speed Great improvement, but did not improve the data reading speed
Therefore, in the file storage system with Hadoop as the core, it is a difficult choice not only to meet the high availability of data, but also to avoid a large consumption of data storage space, and to ensure the speed of reading and writing data.

Abstract

The invention discloses a data storage method, device and equipment and a computer readable storage medium, which can be suitable for a file storage system taking Hadoop as a core, can overcome the defects of a storage mode provided by the existing Hadoop, meets the high availability of data in the file storage system, avoids the large consumption of data storage space, and ensures the read-write speed of the data. The storage method comprises the steps that access attributes of a target storage file in the file storage system are determined, and the access attributes comprise a cold attribute and a hot attribute; generating a target storage strategy matched with the access attribute for the target storage file; querying a historical storage strategy of the target storage file in the file storage system; and according to a comparison result of the target storage strategy and the historical storage strategy, executing a storage operation on the target storage file.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a data storage method, apparatus, device, and computer-readable storage medium. Background technique [0002] With the development of science and technology, in the field of big data, there are many big data components with Hadoop as the core, such as Hive, Spark, Presto, Impala, etc. [0003] The so-called Hadoop is a distributed system infrastructure. Through Hadoop, users can develop distributed programs without knowing the underlying details of the distribution to make full use of clusters for high-speed computing and storage. [0004] In Hadoop, in order to achieve high availability of cluster storage, Hadoop's HDFS file storage system provides two storage methods, Block replication (that is, multiple copies of file blocks) and Erasure coding (that is, erasure coding technology). While improving data availability, it also causes 200% additional overhe...
