Abstract

The invention discloses a data storage and query method and device. The method comprises the steps that when to-be-stored data is stored, a storage space of a content header node and a storage space of a content node are applied for in a content file, a storage address of the content node of the data is stored in the storage space of the content header node, and entity content of the data is stored in the storage space of the content node; and the method further includes storing the index information of the to-be-stored data into an index file, applying for a storage space of the index information in the index file, the index information being dimension information of entity content of the to-be-stored data and a storage address of the entity content in a content node of the content file.By means of the method and device, the effect of optimizing the database storage structure is achieved.

Description

technical field [0001] The invention relates to the field of databases, in particular to a data storage and query method and device. Background technique [0002] At present, there are many types of storage library products on the market, such as hbase, spark, impala, etc. based on Hadoop based on big data, sqlserver, mysql, etc. based on relational database, and non-sql mango, etc., products for various products The needs are different and the functions are different, but it is difficult to find the shortcomings of specific storage solutions. For example, in the demand for storing and analyzing document results, no suitable product can be found after a lot of evaluation and trials. The main needs of users are as follows Features and Storage Requirements: [0003] 1. The amount of data: tens of millions of results, each set of results has thousands of levels of dimension information, each dimension information has multiple sub-results, and each sub-result has multiple attri...
