Anyone who can point me in right direction why I cant import the data to mongodb? When I try to import only the first 100 lines of the total file I get
database-operations git:(master) ✗ node import_acparts_to_mongdb.js (node:10216) Warning: Possible EventEmitter memory leak detected. 11 close listeners added. Use emitter.setMaxListeners() to increas e limit ➜ database-operations git:(master) ✗
I try to import 600.000 lines from the same file, a csv file that has following structure:
facility;item_number;part_name;part_description;net_weight;customs_statistical PBL;5535210444;COVER;COVER;0;84314980 D37;5535211545;BRACKET;BRACKET-FIRE SUPP TANK A101-20;2,939;72169110 PBL;5535211234;BRACKET;BRACKET-FIRE SUPP TANK A101-20;2,939;84314300 PBL;5535212478;RING-SNAP;RING-SNAP;0,045;84314980 ....... .......
