Data loading

After you have deployed your first GraphQL Schema, you get a GraphQL API served on /graphql endpoint and an empty backend. You can populate the graph database using the mutations operations on the GraphQL API.

A more efficient way to populate the database is to use the Dgraph’s import tools.

The first step is to understand the schema mapping and to prepare your RDF files or JSON files to follow the internal Dgraph predicates names. You also have to make sure that you properly generate data for the dgraph.type predicate so that each node is asscociated with it’s type.

If you are using the initial import tool, you can provide the GraphQL schema along with the data to import when executing the bulk load.

If you are using the live import tool, you must first deploy your GraphQL Schema and then proceed with the import. Deploying the schema first, will generate the predicates indexes and reduce the loading time.
