[0050] figure 1 It is a flow chart of a graph database data import method provided according to the first embodiment of the present application. This embodiment is based on MapReudce logic and is used to solve the problem of how to quickly import data into a graph database. The method can be executed by a data importing device of a graph database, which can be implemented in the form of software and / or hardware, and can be integrated into an electronic device carrying a data importing function. Such asfigure 1 As shown, the data import method of the graph database provided in this embodiment may include:

[0051] S110. Determine the first tuple data of edges in the graph data.

[0052] It can be understood that a graph is a map, which is composed of endpoints and edges; where endpoints represent entities such as people, things, objects, and places, and edges represent the relationship between two endpoints. In this embodiment, the graph data is the data to be imported into t...

Abstract

The embodiment of the present application discloses a graph database data import method, device, electronic equipment and media, which relate to the technical field of big data. The specific implementation plan is: determine the first tuple data of the edge in the graph data; according to the original id of the endpoint in the graph data, map the mapping relationship between the original id of the endpoint and the unique id of the endpoint, and the first tuple data of the edge Write the tuple data into at least two fragment files; determine the combination data according to the mapping relationship in the at least two fragment files and the first tuple data of the edge; write the combination data Data files in the graph database. Through the technical solutions of the embodiments of the present application, the data importing speed can be improved.

Description

technical field [0001] The present application relates to data processing technology, in particular to big data technology, and in particular to a data import method, device, electronic device and medium for a graph database. Background technique [0002] In graph databases, data import performance is an important evaluation indicator. When the amount of data reaches a certain level, due to resource limitations such as memory, the import performance of batch data drops sharply. Therefore, finding a data import method that can adapt to large amounts of data is imminent for graph databases. [0003] However, the current batch data import process needs to frequently query data from external storage media such as KV databases, which seriously affects the data import speed. Contents of the invention [0004] Embodiments of the present application provide a data import method, device, electronic device, and medium for a graph database, so as to improve data import speed and fu...
