Importing and Exporting data from Dgraph Cloud

Exporting and Importing Data in Dgraph Cloud

You can export your data as an Administrator from one Dgraph Cloud backend, and then import this data back into another Dgraph instance or Dgraph Cloud backend. For more information about how to export data in Dgraph Cloud, see Export data. You can also export data from Dgraph Cloud programatically using the Dgraph Cloud API. For more information, see Cloud API documentation.

To import data to Dgraph Cloud, see live loader.

Exporting Data with Multi-Tenancy feature enabled in Dgraph Cloud

You can trigger two types of exports:

• Cluster-wide export: this is an export of the entire backend (including all namespaces). This request can be only triggered by the Guardian of Galaxy users.
• Namespace-specific export: this is an export of a specific namespace. This request can be triggered by the Guardian of Galaxy users and by the Guardian of Namespace users.

Cluster-wide Exports

This can only be done by the Guardian of Galaxy users (AKA Super Admin), the steps are:

1. Get the accessJWT token for the Guardian of Galaxy user. Send the following GraphQL mutation to the /admin endpoint:

mutation login($userId: String, $password: String, $namespace: Int) {
  login(userId: $userId, password: $password, namespace: $namespace) {
    response {
      accessJWT
      refreshJWT
    }
  }
}

Your variables should be referring to the Guardian of Galaxy user:

{
	"userId": "groot",
	"password": "password",
	"namespace": 0
}

2. Once obtained the accessJWT token you need to pass it in X-Dgraph-AccessToken Header and only then you can send the following GraphQL mutation to /admin/slash endpoint:

mutation {
  export (namespace: -1) {
    response { code message }
    exportId
    taskId
  }
}

3. Once done, you can now send the following GraqhQL mutation to get the signedUrls from where you can download your export files:

query {
  exportStatus (
    exportId:"<paste-your-exportId>"
    taskId: "<paste-your-taskId>"
  ){
    kind
    lastUpdated
    signedUrls
    status
  }
}

Namespace-specific Exports

Namespace-specific exports can be triggered by the Guardian of Galaxy users. In this case you can follow the same steps for the Cluster-wide exports and replace the namespace value from -1 to the namespace you want to export. It’s important that you get the accessJWT token for the Guardian of Galaxy user and pass it in the X-Dgraph-AccessToken header.

E.g. if you want to export the namespace 0x123 your GraphQL request sent to the /admin/slash endpoint would look like:

mutation {
  export (namespace: 123) {
    response { code message }
    exportId
    taskId
  }
}

You can also trigger namespace-specific export using the Guardian of Namespace users, in this case there is no need to specify any namespace in the GraphQL request as these users can only export their own namespace. It’s important that you get the accessJWT token for the Guardian of Namespace user and pass it in the X-Dgraph-AccessToken header.

The GraphQL request sent to the /admin/slash endpoint would be:

mutation {
  export {
    response { code message }
    exportId
    taskId
  }
}
