Я пытаюсь импортировать файл csv в orientdb 3.0. Я создал и протестировал файл json, и он работает с меньшим набором данных. Но набор данных, который я хочу импортировать, составляет около миллиарда строк (шесть столбцов)
Ниже приведен файл user.json, который я использую для импорта с помощью oetl
{
"source": { "file": { "path": "d1.csv" } },
"extractor": { "csv": {} },
"transformers": [
{ "vertex": { "class": "User" } }
],
"loader": {
"orientdb": {
"dbURL": "plocal:/databases/magriwebdoc",
"dbType": "graph",
"classes": [
{"name": "User", "extends": "V"}
], "indexes": [
{"class":"User", "fields":["id:string"], "type":"UNIQUE" }
]
}
}
}
Это вывод консоли из команды oetl:

Я знаю, что код правильный, но я предполагаю, что это больше проблема с памятью!
Пожалуйста, посоветуйте, что мне делать.
