Problems solved by technology

A piece of data may have many tags, so a piece of data may need to establish multiple indexes, which puts a lot of pressure on data storage, especially when the amount of data is huge, the efficiency of data storage is very low. At the same time, A large number of indexes also cause index expansion, wasting unnecessary storage space

Abstract

The embodiment of the invention provides a data storage method and device, when data is stored, all label values of the data are used for determining the label index of the data, and only one label index used for data query needs to be established for one piece of data. When the data needs to be retrieved; retrieval-based conditions, determining a label index of the target data to be retrieved, according to the embodiment of the invention, the number of the label indexes which need to be stored in the HBASE database library at the same time when the data is stored in the HBASE database libraryis effectively reduced, the data storage efficiency is improved, and the storage space is saved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a data storage method and device. Background technique [0002] With the rise of big data today, HBASE (distributed storage database) as a columnar database occupies an important position in data storage and retrieval. HBASE is different from general relational databases. It is a database suitable for unstructured data storage. It has the characteristics of high reliability, high performance, column-oriented, scalable, good scalability, seamless horizontal expansion, and open source. [0003] When data is stored in HBASE, HBASE can create an index for the label (attribute) of each data. When searching for data with a certain label, the user can use the above index to query the corresponding data. A piece of data may have many tags, so a piece of data may need to establish multiple indexes, which puts a lot of pressure on data storage, especially when the ...
