Importing mongo collection into existing collection without overriding it

由 好久不见. 提交于 2019-12-08 08:24:35
问题 Is it possible to import a mongodump into a existing collection adding to it (not overriding it)? If yes, how? Would it be using mongoimport --db mydb ? The collections are the same in structure but simple have different datasets from different instances of the same app. I'd like to merge all data into a single database. 回答1: Use mongorestore. It is overwriting the collection only if you specify --drop parameter. So if you do nothing it will just add new element (thus doing what you want).

Import csv data as array in mongodb using mongoimport

I have been trying to import the csv data into mongodb using mongoimport. The collection is like this: { id:"122234343", name: "name1", children: ["222334444","333344444"] } One approach I tried is to create 2 csv files - one with id & name and other with id, children (if id has two children then it will have two rows). Import the data into two different collections using mongoimport and then use update the collection data using foreach() at second collection having children data. Please suggest is there any another way to populate this "children" array directly from CSV?? To me, the simplest

I just moved to a new laptop which had mongo 3.0.0 I believe. On the new laptop I have mongo 3.0.4. and trying the script that was working on the old laptop is giving me errors.
