The programming model can be divided into three parts, namely a Data Source Operator, a Data conversion Operator and a Data stream output Operator, wherein the Data Source Operator, the Data conversion Operator and the Data stream output Operator are used for processing Data in real time.
Neo4j is a high-performance NOSQL graph database that stores structured data on a network to form graphs rather than directly in tables, and Neo4j can also be considered as a high-performance graph engine with all the features of a sophisticated database, such as: transactions, indexes, etc. programmers work under an object-oriented, flexible network architecture rather than a strict, static table, but they can enjoy all the benefits of having a full transactional nature, an enterprise-level database. Two basic data types are contained in a graph: nodes and Relationships, wherein the Nodes and the Relationships comprise attributes in the form of keys and values, and the Nodes are connected through the Relationships defined by the Relationships to form a relational network structure.
And (3) node: the basic elements that make up a graph are nodes and relationships, which in Neo4j may both contain attributes, nodes are often used to represent some entities, but dependencies may also represent entities.
The relationship is as follows: relationships between nodes are an important part of graph databases, and many associated data such as node sets, relationship sets and their attribute sets can be found through the relationships.

Writing a Flink code according to requirements, creating nodes and relations and writing data in real time:
1) the user-defined funnation implementation method and the logic code are as follows:
public class Neo4jSink extends RichSinkFunction<Dict>{};
2) the main class processes the data using Flink and writes to Neo4j in real time:
public class DaRunFaNeo4j{};
3) and analyzing the custom tool class of the Json data:
public class JsonUtil{};
4) self-defining a connection tool class:
public class ZxDataUtil{};
5) self-defining task parameter setting tool class:
public class FlinkUtil{}。
optionally, before writing data in Neo4j graph database in real time using Flink real time stream, the method further comprises: and setting by adopting a checkpoint mechanism so as to save the state of the stream processing operation.
Analyzing the processed data, writing the data in real time by using a Flink-DataStream, setting by adopting a checkpoint mechanism, and storing the state of the stream processing operation:
public static StreamExecutionEnvironment getEnv(){
StreamExecutionEnvironment env=StreamExecutionEnvironment.getExecutionEnvironment();
enable checkpoint, specifying the time interval (unit: ms, default 500 ms) to trigger checkpoint, default is env.
// set Checkpoint timeout to default to 10 minutes
env.getCheckpointConfig().setCheckpointTimeout(18PA03060);
If there is a more recent save point, whether to rollback the job to that checkpoint
env.getCheckpointConfig().setPreferCheckpointForRecovery(true);
// set number of checkpoint failures that can be allowed
env.getCheckpointConfig().setTolerableCheckpointFailureNumber(3);
At least once
env.getCheckpointConfig().setCheckpointingMode(CheckpointingMode.AT_LEAST_ONCE);
return env;
}
