Problems solved by technology

[0004] However, since the data in the key-value store database is not structured, it cannot support structured queries well
In order to solve this kind of problem, in the prior art, some specific storage structures are usually pre-defined, but it can only perform structured queries on the data stored according to these storage structures, which has great limitations

Abstract

The application provides a data query method, device, a data storage server and system. A client sends the at least one target identifier and at least one target data attribute for querying the targetdata to a data storage server; therefore, after the data storage server can obtain the data packet corresponding to each target identifier in the database, the target data corresponding to each target data attribute can be directly filtered from the data package. The present invention realizes structured query of target data, and the present application does not depend on a specific storage structure, has universality, and improves the flexibility and efficiency of data structured query. Moreover, since the data storage server only sends the obtained target data to the client, which avoids the occupation of network resources by irrelevant data in the data packet being sent to the client, which greatly reduces the data processing burden on the client.

Description

technical field [0001] This application mainly relates to the field of database application, and more specifically relates to a data query method, device, data storage server and system. Background technique [0002] With the rise of Internet web2.0 websites, traditional relational databases are unable to cope with web2.0 websites, especially ultra-large-scale and high-concurrency SNS-type web2.0 pure dynamic websites, and many insurmountable problems have been exposed. . Therefore, currently, in most Internet applications, a NoSQL database (Not Only SQL, non-relational database) is usually used for data storage. [0003] Among them, key-value (Key-Value) storage database is currently a commonly used NoSQL database, and its data will be stored in the form of key-value, which can effectively reduce the number of reads and writes to disk, and has better read and write performance than relational database storage. , and has strong scalability. [0004] However, since the dat...
