Neo4j Connector for Apache Spark
The Neo4j Connector for Apache Spark provides integration between Neo4j and Apache Spark.
You can use the connector to process and transfer data between Neo4j and other platforms such as Databricks and several data warehouses. Based on the Spark DataSource API, the connector supports all the programming languages that Spark supports.
Graphs and DataFrames
The connector uses schema inference to convert Neo4j graphs into Spark table-based DataFrames. For example, consider a graph with the following schema:
The connector creates a DataFrame with :Customer and :Product nodes connected by the BOUGHT relationship, along with any node or relationship properties.
The Schema inference section shows a more detailed example of this process, while the Data type mapping section shows how data types are mapped between Neo4j and Spark.
