Export Neo4j Database: A Comprehensive Guide

How to Export a Neo4j Database

Exporting Entire Databases

Use the neo4j-admin tool to export entire databases in Neo4j Community Server. Access this functionality via the console to dump and load database backups. For Neo4j Enterprise edition, utilize the backup command for similar operations.

Exporting Data with APOC

Implement the APOC library for exporting specific data sets, including complete databases, subgraphs, or Cypher query results. APOC supports exporting into JSON, CSV, GraphML, and Cypher script formats for versatile data handling.

Exporting Query Results

For exporting the results of a query, use the apoc.export.json.query procedure to get JSON formatted data. Alternatively, the Export to GraphML procedure is available for GraphML data exports. Avoid using apoc.export.cypher.query as it may not export all relationships.

Exporting Database Schema

Execute the call graph.db.schema.export(Cypher query) command to export the schema of your Neo4j database, ensuring a reliable replication of the database structure.

Frequently Asked Questions

How can I export my entire Neo4j database?

To export an entire Neo4j database, you can use the 'neo4j-admin' tool with the dump command. This tool needs to be run from the terminal and only works with the Neo4j Community Server. Ensure you have Java Runtime installed, and the $JAVA_HOME environmental variable set correctly. Use the tool by navigating to the bin directory of your Neo4j installation and running the appropriate backup command.

How do I export a graph to JSON in Neo4j?

To export a graph to JSON, you can utilize the APOC library, which adds support for exporting data into various formats including JSON. You can choose to export specified nodes, relationships, a virtual graph, or the results of a Cypher query.

Why is the JSON format different when exporting from APOC compared to the Neo4j browser?

The JSON format differences stem from the distinct methods APOC and the Neo4j browser use to serialize data. APOC provides a more flexible and comprehensive way to export data, which can result in a format that differs from the more standardized JSON export available in the Neo4j browser.

How can I get my data in the 'Table' format returned by a Cypher 'MATCH p=()-->() RETURN p' query?

The 'Table' format is typically seen in the Neo4j browser and represents a visual and tabular representation of the results from a Cypher query. To export this data, you would need to use the browser's export functionality, as the 'neo4j-admin' tool does not support exporting sub-graphs or specific query results into a 'Table' format.

Common Use Cases

•

• 
  Analyzing and processing Neo4j data offline or in a separate tool
• 
  Sharing a snapshot of a Neo4j dataset with collaborators or for public release
• 
  Transitioning data from Neo4j to another database system or format
