One-to-one relations

It's possible to create one-to-one relations in schema. Those relations will be then available for querying via GraphQL.
Define relations in schema
To define one-to-one relation nested entity must have id field that is either String! or ID!. In parent entity create field (with any name) that is of nested entity's type (can be nullable or required).
type Space {
  id: String!
  name: String
}
​
type Proposal {
  id: String!
  name: String
  space: Space!
}
Create entities in writer 
When creating entities in writer set Proposal's space field to the value of Space's id field.
const proposal = {
  id: 'proposal_id',
  name: 'Proposal name',
  space: 'space_id'
}
​
await mysql.queryAsync('INSERT INTO proposals SET ?', [proposal]);
Query data via GraphQL
It's now possible to nest space entity when querying proposals. You can still filter proposals by space (limited to Space's id currently).
{
  proposals(first: 10, where: {space: "0x00b60f2a154b9aaec8e4bec8e04f86d6cd92a9c993871e904bd815962603492d"}) {
    id
    space {
      id
      name
    }
  }
}
