I need to import 14 mil. nodes from a csv.
After some efforts with threaded apoc.import.csv, came upon the import using neo4j-admin
at this link Importing CSV Data into Neo4j - Developer Guides
Well, it did import all 14mil nodes in like 2 minutes,
but!....database (4.2.6) is now dead, won't start:
"DBMS failed to restart: Error: Could not call remote method 'databaseStatistics'. Check that the method signature is correct. Underlying error: Cannot destructure property 'nodes' of 'e' as it is undefined. Underlying stack: TypeError: Cannot destructure property 'nodes' of 'e' as it is undefined. at t.default.databaseStatistics (D:\Program Files\Neo4j Desktop\resources\app.asar\dist\main.prod.js:1:119309) at electron/js2c/browser_init.js:6651:63 at EventEmitter.

Note 1: did the same (confing, setup) with 4.2.5 and it worked. Will try again with 4.2.6
Note 2: worked also with 4.2.6 - this time i've ramped up all possible RAM usage, meaning
The only difference between 3 try and first try (which failed) is in the pagecache, which I've left to the default 512m.
