ArangoDB - 如何将neo4j 数据库导出导入ArangoDB

Question

Are there any utilities to import database from Neo4j into ArangoDB? arangoimp utility expects the data to be in certain format for edges and vertices than what is exported by Neo4j.

Thanks!

Answer 1

Note: This is not an answer per se, but a comment wouldn't allow me to structure the information I gathered in a readable way.

Resources online seem to be scarce w/r to the transition from neo4j to arangodb.

One possible way is to combine APOC ( https://github.com/neo4j-contrib/neo4j-apoc-procedures ) and neo4j-shell-tools ( https://github.com/jexp/neo4j-shell-tools )

1. Use apoc to create a cypher export file for the database (see https://neo4j.com/developer/kb/export-sub-graph-to-cypher-and-import/ )
2. Use the neo4j-shell-tool cypher import with the -o switch -- this should generate csv-files
3. Analyse the csv-files,
   1. massage them with csvtool OR
   2. create json-data with one of the numerous csv2json converters available (npm, ...) and massage these files with jq
4. Feed the files to arangoimp, repeat 3 if necessary

There is also a graphml to json converter ( https://github.com/uskudnik/GraphGL/blob/master/examples/graphml-to-json.py ) available, so that you could use the afforementioned neo4j-shell-tools to export to graphml, convert this representation to json and massage these files to the necessary format.

I'm sorry that I can't be of more help, but maybe these thoughts get you started.
