Patch Changes

• 6aed171: Allows MergedTypeConfig to be written with an entryPoints array for multiple merged type entry points, each with their own fieldName and selectionSet:

  {
    schema: testSchema,
    merge: {
      Product: {
        entryPoints: [{
          selectionSet: '{ id }',
          fieldName: 'productById',
          key: ({ id, price, weight }) => ({ id, price, weight }),
          argsFromKeys: (key) => ({ key }),
        }, {
          selectionSet: '{ upc }',
          fieldName: 'productByUpc',
          key: ({ upc, price, weight }) => ({ upc, price, weight }),
          argsFromKeys: (key) => ({ key }),
        }],
      }
    }
  }

  These multiple entry points accommodate types with multiple keys across services that rely on a central service to join them, for example:

  • Catalog service: type Product { upc }
  • Vendors service: type Product { upc id }
  • Reviews service: type Product { id }

  Given this graph, the possible traversals require the Vendors service to provide entry points for each unique key format:

  • Catalog > Vendors > Reviews
  • Catalog < Vendors > Reviews
  • Catalog < Vendors < Reviews

  Is it highly recommended that you enable query batching for subschemas with multiple entry points.
