Test collection collection1 contains 1 million documents with size about 500Mb. The replica set consists of three MongoDB 4.2 members. We'll test performance on replica set cluster in local network. We hope this small research will help to find the fastest way for you. We'll measure cloning time, point advantages and disadvantages, compare usability (5-point scale, higher value is better) for each way. Join 1000s of developers learning about Enterprise-grade Node.There are several ways how to clone a collection within the same or to a different MongoDB database. Take your JavaScript testing to the next level by learning the ins and outs of Jest, the top JavaScript testing library. Unsplash-logo Cameron Kirby Get The Jest Handbook (100 pages) If you’re looking for a good place to host your Dokku instance, I recommend DigitalOcean, they have a great One-click install and deploy Dokku, if you use this referral link you’ll get $100 free credit. I would also suggest using dokku mongo:unexpose YOUR_DATABASE_NAME when not actively using the connection.įor more about Dokku and deployment see: Deployment options: Netlify + Dokku on DigitalOcean vs now.sh, GitHub Pages, Heroku and AWS or the “Deployment” category on Code with Hugo These connections are not done with TLS (transport layer security), which is fine for non-sensitive data. > db.getCollection ( 'newest-public-spaces' ).find ( Security concerns Ssh -t _SERVER_IP mongo:connect public-database Let’s disconnect and go back to the dokku-mongo plugin connection and get data for the newest-public-spaces collection to see if we were talking to the same database. You can “Save” and “Connect” to this new databaseĬreate a new collection “newest-public-spaces”.You can now hit “Test” and it should tell you everything is fine.Password: 289b4a4b32ab3182895d8aac7def0ee1 (use your actual password).The format is mongodb://USERNAME: _HOSTNAME:INTERNAL_PORT/DATABASE_NAME.Fill out the “Authentication” tab, if you remember our connection string from dokku mongo:info public-database, **mongodb://public-database: :27017/public-database**.Fill out the “Connection” tab, of course, replace YOUR_SERVER_IP with your actual server IP or domain name.Open the “Connect” menu (File > Connect).In order to connect with Robo3T we’ll create a new connection to the MongoDB instance. We’ll need to expose it, and pass some ports we want to map to (this helps with predictability/reproducibility) That means this MongoDB instance is not exposed to anything outside of Dokku, that’s good for security, bad for accessing it from your local tools. If we look back at the mongo:info output we’ll notice the following line: Exposed ports:. It should open a MongoDB shell: MongoDB shell version v3.4.9Ĭonnecting to: mongodb://127.0.0.1:27017/public-databaseĭokku’s behaviour around access of MongoDB Run the following command: ssh -t _INSTANCE_IP mongo:connect public-database Service root: /var/lib/dokku/services/mongo/public-databaseĬonnect to your remote MongoDB instance on Dokkuįirst off, let’s check that we can connect using the included dokku-mongo :connect command. => MongoDB container created: public-databaseĬonfig dir: /var/lib/dokku/services/mongo/public-database/configĭata dir: /var/lib/dokku/services/mongo/public-database/dataĭsn: mongodb://public-database: :27017/public-database You should get the following output, the bolded string is the mongo connection URI: Waiting for container to be ready
