Restore neo4j graph from a huge dump

I have a huge dump of my graph in a file (i.e. 550k lines of CRATEs) and I need to restore it. I tried from terminal

neo4j-shell -file backup.cypher

...but after 24 hours the transaction was not committed, then I stopped it.

Is there another way to restore my data?

Split up the creates into individual ones, separated by semicolon. then wrap 50k of them each into a begin ... commit block.

for the relationships, change them to a match + match + create statement to find the two nodes and create the relationship.

You can split your dump file to multiple files and run restore for each of it.

But be aware there could be references between CREATE clauses.
