We have a 60GB database in orientdb (3.x) and need to import the same into neo4j. Currently, we are using Gremlin (3.6.1) to convert the orientdb data to a graphml format and trying to import the same into neo4j. We have configured gremlin on an EC2 instance with 64GB RAM, but getting Java heap memory error. What is the ideal RAM configuration required for this process? If there is a different process to achieve the same, pls let us know. Thank you
Thank you for the response. So we are converting the orientdb to graphml using Gremlin. During that process, Gremlin was throwing Java heap memory error. Unless we have that graphml file, we cannot import into neo4j. Please let me know if there is a different process to achieve the same. Thank you
As said I have no knowledge of orientdb, but I assume there are ways to export the data from it. Maybe you can dump the data to a CSV file and import that into Neo4j. Alternatively you can write a Orientdb client that is also a Neo4j client and do the conversion that way.
