Neo4j Export Database to Cypher Tutorial

Understanding Export Procedures

The Neo4j export to Cypher functionality allows you to export your database as Cypher statements. These statements can be utilized to replicate your dataset in a different Neo4j instance. Unique labels and IDs are assigned to nodes during the export process to maintain node uniqueness.

Using apoc.export.cypher.all

The apoc.export.cypher.all procedure is an efficient way to export your entire Neo4j database. It is designed for easy import through the Neo4j Browser, using the "plain" configuration format. When executed, it provides comprehensive details about the export such as file location, nodes, relationships, and more.

Export Formats and Configurations

Graph entities can be exported using the Cypher CREATE or MERGE clauses. The cypherFormat: "updateAll" option allows using MERGE to preserve existing entities. To add relationships to an existing graph, use cypherFormat: "addStructure". For updating relationships, cypherFormat: "updateStructure" is suitable. The procedure apoc.export.cypher.query lets you export specific queries and the "separateFiles" configuration determines if the output will be in separate files.

Streaming and Troubleshooting Export

To stream Cypher statements rather than saving to a file, use the provided streaming options. To troubleshoot any issues during import, apply the --debug command line parameter. For memory-intensive operations, adjust the dbms.memory.heap.max_size setting in your neo4j.conf file accordingly.

Post-Export Cleanup

After the export, temporary labels and properties such as UNIQUE IMPORT LABEL and UNIQUE IMPORT ID are removed. To further manage the imported data and constraints, use the apoc.cypher.runSchemaFile, apoc.cypher.runFiles, or apoc.cypher.runFile procedures as needed.

Frequently Asked Questions

How do you export the entire Neo4j database to a Cypher file?

To export the entire Neo4j database to a Cypher file, use the apoc.export.cypher.all procedure.

Can the format of the exported Cypher file be specified?

Yes, the format of the export can be specified using the format parameter, which can be set to 'neo4j-shell', 'plain', or left at the default which exports in the Cypher Shell format.

Is it possible to export to multiple files when using the APOC export procedures?

Yes, the apoc.export.cypher.data procedure supports writing to multiple files or multiple columns by enabling the separateFiles: true config.

How can you import the exported Cypher statements into another Neo4j database?

The exported Cypher statements can be imported into another Neo4j database using Cypher Shell, Neo4j Shell, or the apoc.cypher.runFile procedure after setting the apoc.import.file.enabled property to true.

What should you do if you need to stream the export statements rather than writing them to a file?

To stream the export statements, you can use the apoc.export.cypher.query procedure, which allows streaming into Neo4j Browser with the format set to 'plain' or streamed into Cypher Shell.

Common Use Cases

• 
  Migrating a Neo4j database to another environment
• 
  Creating a backup of the graph data for disaster recovery
• 
  Sharing the database schema and data with collaborators for analysis
• 
  Documenting the database structure for audit and compliance purposes
• 
  Seeding a development or test environment with production data
