Abstract

The invention provides a system and a method for writing data into a graph database based on NiFi. The system comprises a graph database, a data stream platform comprising a processing module and a plurality of data execution nodes, and a plurality of relational databases storing data tables. The modeling control platform in the graph database is configured to designate the data source informationof the data tables to be synchronized, and the graph data model corresponding to each data table to be synchronized is established. The processing module uses NiFi to call the interface of graph database to generate NiFi data flow including several SQL statements according to the data source information and executes the NiFi data flow to distribute the several SQL statements to each data execution node. The data execution node executes distributed SQL statements to load a data set to be synchronized obtained from its corresponding data table into a graph data model corresponding to the data table. Therefore, this scheme can write the data from the relational database into the graph database.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a system and method for writing data into a graph database based on NiFi. Background technique [0002] With the generation and application of ultra-large-scale and high-concurrency social network data, traditional relational databases have exposed insurmountable problems. For example, when it is necessary to analyze the potential relationship between entities in the existing relational database, the existing relational database has the characteristics of poor performance and cumbersome and complicated schemes in dealing with relations. [0003] A graph database is a new type of database different from a relational database. It can handle large-scale data and respond to changing needs, and quickly solve complex relational problems. In this way, the data in the relational database needs to be written into the graph database. Contents of the invention [0004] The invention p...
