AI Technical Summary

Problems solved by technology

With such a large amount of data, conventional computer systems cannot load all the data into the system memory, and obtaining data from the hard disk will cause a very large query delay
[0005] At the same time, the data frequently queried by users only accounts for a small part of the overall data, so loading all the data into the system memory will cause unnecessary additional overhead

Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0036] A user-oriented graph database query optimization method, comprising the following steps:

[0037] For occasions where the amount of data cannot be fully loaded into the system memory, on the basis of no user query data, according to the frequency of data acquisition, the data with the highest acquisition frequency is used as hot data, and the hot data is loaded into the system memory first ;

[0038] For user query data, the data that m...

Abstract

The invention belongs to the field of graph data processing, and discloses a user-oriented graph database query optimization method and system, and the method comprises the following steps: taking data with the highest acquisition frequency as hotspot data according to the acquisition frequency of the data on the basis that no user queries the data under the occasion that the data volume cannot be completely loaded into a system memory; preferentially loading the hotspot data into a system memory; for the user query data, preferentially acquiring data matching the user query data from the data in the system memory, and if the data in the system memory cannot match the user query data, acquiring the data matching the user query data from the hard disk; compared with the existing method, the method provided by the invention can improve the query efficiency.

Description

technical field [0001] The disclosure belongs to the field of graph data processing, and in particular relates to a user-oriented graph database query optimization method and system. Background technique [0002] Graph data is a database whose core is the relationship between nodes and nodes. Compared with traditional relational databases, graph databases have great advantages in the study of entity associations, because they are widely used in social networks, the Internet, finance, and artificial intelligence. Intelligence and many other fields. A typical representative of graph-structured data is a knowledge graph, where nodes represent entities and edges represent relationships between entities. Similarly, social networks are also a typical graph data, where nodes represent users and edges represent relationships between users. [0003] As an emerging database dedicated to storing graph-structured data, graph database provides functions such as graph data storage and qu...
