Dsync is currently in beta and is undergoing active development and testing.
Download the latest release from the GitHub Releases page. Note that on Mac devices you may need to configure a security exception to execute the binary by following these steps.
Alternatively, you can build dsync from the source code.
git clone https://github.com/adiom-data/dsync.git
cd dsync
go build
If you already have the desired destination MongoDB instance up and running, you can skip this step.
Install MongoDB
Start a local MongoDB instance:
mkdir ~/temp
cd ~/temp
mkdir data_d
mongod --dbpath data_d --logpath mongod_d.log --fork --port 27017
# You can use our publicly accessible (read-only) Cosmos DB instance
export COSMOS_DEMO=$(echo bW9uZ29kYjovL2Nvc21vc2RiLWRlbW8taW5zdGFuY2U6SkhiRWpRb2JkWm03YWJEcFp2UzZrWHpBMDRXNTBJd2V4QmlQYnVJWFQ2TElmNkhsV2V4YWphQzhkd042REJ2YVh6ajBnclFrdkwzY0FDRGJONjdxZWc9PUBjb3Ntb3NkYi1kZW1vLWluc3RhbmNlLm1vbmdvLmNvc21vcy5henVyZS5jb206MTAyNTUvP3NzbD10cnVlJnJlcGxpY2FTZXQ9Z2xvYmFsZGImcmV0cnl3cml0ZXM9ZmFsc2UmbWF4SWRsZVRpbWVNUz0xMjAwMDAmYXBwTmFtZT1AY29zbW9zZGItZGVtby1pbnN0YW5jZUA= | base64 --decode)
# Feel free to use your own MongoDB connection string
export MDB_DEST='mongodb://localhost:27017'
./dsync --progress --logfile dsync.log $COSMOS_DEMO $MDB_DEST
Now Dsync should be running! Feel free to interrupt the sync process (via Ctrl+C) it once the initial sync is done. The demo database has a few million records and the resources are shared - allow 5-10 minutes for the process to complete.
mongosh $MDB_DEST
Congratulations! You should be able to access the 'odc' database and see the collections in it that were migrated from the Cosmos DB.
