Importing and Exporting data from Dgraph Cloud

You can export your data from one Dgraph Cloud backend, and then import this data back into another Dgraph instance or Dgraph Cloud Backend.

Exporting Data

You can export your data using JSON format. To do this, call the export mutation on /admin/slash. As an example, if your GraphQL endpoint is at https://frozen-mango.us-west-2.aws.cloud.dgraph.io/graphql, then the /admin endpoint for the schema is at https://frozen-mango.us-west-2.aws.cloud.dgraph.io/admin/slash.

The following is an example of a GraphQL mutation to export data to JSON.

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

Make sure to keep your exportId and taskId safe as you will need them for getting the signed URLs in order to download your export files. These URLs will be returned in the signedUrls output field and they expire after 48 hours.

Export will usually return 3 files:

• g01.gql_schema.gz: The GraphQL schema file. This file can be re-imported via the Schema APIs
• g01.json.gz: the data from your instance, which can be imported via live loader
• g01.schema.gz: This file is the internal Dgraph schema. If you have set up your backend with a GraphQL schema, then you should be able to ignore this file.

The following is an example of GraphQL query to check the status of the export and get the signed URLs for downloanding your export files.

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

Exporting Data with Multi-Tenancy feature enabled

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
  }
}

Importing data with Live Loader

It is possible to import data into a Dgraph Cloud backend using live loader. In order to import data, do the following steps:

1. First import your schema into your Dgraph Cloud backend, using either the Schema API or via the Schema Page.
2. Log into Dgraph Cloud, and find your backend’s gRPC Endpoint on the Settings page. This will look like frozen-mango.grpc.us-west-1.aws.cloud.dgraph.io:443

3. Run the live loader as follows:

   docker run -it --rm -v /path/to/g01.json.gz:/tmp/g01.json.gz dgraph/dgraph:v21.03-slash \
     dgraph live --slash_grpc_endpoint=<grpc-endpoint>:443 -f /tmp/g01.json.gz -t <api-token>
