Runtime API couples all models with single datasource

[craicoverflow]

The runtime APIs exposed the server app assumes each model is mapped to a single data-source.

[craicoverflow]

Each model could have their own data source defined.

"""
@model dataSource: 'usersDb'
"""
type User {
  ...
}

"""
@model dataSource: 'shopDb'
"""
type Shop {
  ...
}

would generate the following models.ts array:

export const models = [
  {
    name: "Shop",
    dataSource: "shopDb"
    pubSub: {
      publishCreate: true,
      publishUpdate: true,
      publishDelete: true,
    },
  },
  {
    name: "User",
    dataSource: "usersDb",
    pubSub: {
      publishCreate: true,
      publishUpdate: true,
      publishDelete: true,
    },
  },
]

const dbConfigs = [
{
  name: "shopDb",
  client: "pg",
  default: true,
  config: {
    ...
  }
},
{
  name: "usersDb",
  client: "mongo",
  config: {
    ...
  }
}
]

const services = createDataSources(models, schema, dbConfigs, puSub);
