mongomove

This tool imports your databases from one MongoDB server to another. I use this package when I need to import databases from MongoDB Atlas to my local machine for development.

Install

Binary

go install github.com/bounoable/mongomove/cmd/mongomove@latest

As a library

go get github.com/bounoable/mongomove

Import all databases

Import all databases from mongodb://127.0.0.1:27017 to mongodb://127.0.0.1:27018:

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018

Filter databases by prefix

Import all databases that have the my_ prefix from mongodb://127.0.0.1:27017 to mongodb://127.0.0.1:27018:

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -prefix my_

Skip confirmation

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -confirm

Insert documents in batches

Default batch size is 100. Following command inserts documents in batches of 500 documents:

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -b 500

Parallelize import

By default mongomove uses the number of CPUs to parallelize the import, so that 1 CPU is importing 1 database at a time. The following command imports 2 databases concurrently until all databases have been imported:

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -p 2

Disable index creation

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -indexes false

Verbose output

mongomove -source mongodb://127.0.0.1:27017 -target mongodb://127.0.0.1:27018 -v
