   * This method will only be called once to instantiate the singleton
   * service, which can then be accessed via `store.schema`.
   *
   * For Example, to use the default SchemaService for SchemaRecord
   *
   * ```ts
   * import { SchemaService } from '@warp-drive/schema-record';
   *
   * class extends Store {
   *   createSchemaService() {

   * class extends Store {

   *     const schema = new SchemaService();
   *     return new DelegatingSchemaService(this, schema);
   *   }
   * }
   * ```

   * When using the DelegateSchemaService, the schema will first
   * be sourced from directly registered schemas, then will fallback

  /**
   * Issue a request via the configured RequestManager,

   *
   * ## Cache Keys
   *
   * Only GET requests with a url or requests with an explicit
   * cache key (`cacheOptions.key`) will have the request result
   * and document cached.
   *
   * The cache key used is `requestConfig.cacheOptions.key`
   * if present, falling back to `requestConfig.url`.
   *
   * Params are not serialized as part of the cache-key, so
   * either ensure they are already in the url or utilize
   * `requestConfig.cacheOptions.key`. For queries issued
   * via the `POST` method `requestConfig.cacheOptions.key`
   * MUST be supplied for the document to be cached.
   *
   * ## Requesting Without a Cache Key
   *
   * Resource data within the request is always updated in the cache,
   * regardless of whether a cache key is present for the request.
   *
   * ## Fulfilling From Cache
   *
   * When a cache-key is determined, the request may fulfill
   * from cache provided the cache is not stale.
   *
   * Cache staleness is determined by the configured CachePolicy
   * with priority given to the `cacheOptions.reload` and
   * `cacheOptions.backgroundReload` on the request if present.
   *
   * If the cache data has soft expired or the request asks for a background
   * reload, the request will fulfill from cache if possible and
   * make a non-blocking request in the background to update the cache.
   *
   * If the cache data has hard expired or the request asks for a reload,
   * the request will not fulfill from cache and will make a blocking
   * request to update the cache.
   *
   * ## The Response
   *
   * The primary difference between `requestManager.request` and `store.request`
   * is that `store.request` will attempt to hydrate the response content into
   * a response Document containing RecordInstances.

  /**
    This method returns a record for a given identifier or type and id combination.

    The `findRecord` method will always resolve its promise with the same
    object for a given identifier or type and `id`.

    The `findRecord` method will always return a **promise** that will be
    resolved with the record.

    **Example 1**

    ```app/routes/post.js
    export default class PostRoute extends Route {
      model({ post_id }) {
        return this.store.findRecord('post', post_id);
      }
    }
    ```

    **Example 2**

    `findRecord` can be called with a single identifier argument instead of the combination
    of `type` (modelName) and `id` as separate arguments. You may recognize this combo as
    the typical pairing from [JSON:API](https://jsonapi.org/format/#document-resource-object-identification)

    ```app/routes/post.js
    export default class PostRoute extends Route {
      model({ post_id: id }) {
        return this.store.findRecord({ type: 'post', id });
      }
    }
    ```

    **Example 3**

    If you have previously received an lid via an Identifier for this record, and the record
    has already been assigned an id, you can find the record again using just the lid.

    ```app/routes/post.js
    store.findRecord({ lid });
    ```

    If the record is not yet available, the store will ask the adapter's `findRecord`
    method to retrieve and supply the necessary data. If the record is already present
    in the store, it depends on the reload behavior _when_ the returned promise
    resolves.

    ### Preloading

    You can optionally `preload` specific attributes and relationships that you know of
    by passing them via the passed `options`.

    For example, if your Ember route looks like `/posts/1/comments/2` and your API route
    for the comment also looks like `/posts/1/comments/2` if you want to fetch the comment
    without also fetching the post you can pass in the post to the `findRecord` call:

    ```app/routes/post-comments.js
    export default class PostRoute extends Route {
      model({ post_id, comment_id: id }) {
        return this.store.findRecord({ type: 'comment', id, { preload: { post: post_id }} });
      }
    }
    ```

    In your adapter you can then access this id without triggering a network request via the
    snapshot:

    ```app/adapters/application.js
    export default class Adapter {

      findRecord(store, schema, id, snapshot) {
        let type = schema.modelName;

        if (type === 'comment')
          let postId = snapshot.belongsTo('post', { id: true });

          return fetch(`./posts/${postId}/comments/${id}`)
            .then(response => response.json())
        }
      }

      static create() {
        return new this();
      }
    }
    ```

    This could also be achieved by supplying the post id to the adapter via the adapterOptions
    property on the options hash.

    ```app/routes/post-comments.js
    export default class PostRoute extends Route {
      model({ post_id, comment_id: id }) {
        return this.store.findRecord({ type: 'comment', id, { adapterOptions: { post: post_id }} });
      }
    }
    ```

    ```app/adapters/application.js
    export default class Adapter {
      findRecord(store, schema, id, snapshot) {
        let type = schema.modelName;

        if (type === 'comment')
          let postId = snapshot.adapterOptions.post;

          return fetch(`./posts/${postId}/comments/${id}`)
            .then(response => response.json())
        }
      }

      static create() {
        return new this();
      }
    }
    ```

    If you have access to the post model you can also pass the model itself to preload:

    ```javascript
    let post = await store.findRecord('post', '1');
    let comment = await store.findRecord('comment', '2', { post: myPostModel });
    ```

    ### Reloading

    The reload behavior is configured either via the passed `options` hash or
    the result of the adapter's `shouldReloadRecord`.

    If `{ reload: true }` is passed or `adapter.shouldReloadRecord` evaluates
    to `true`, then the returned promise resolves once the adapter returns
    data, regardless if the requested record is already in the store:

    ```js
    store.push({
      data: {
        id: 1,
        type: 'post',
        revision: 1
      }
    });

    // adapter#findRecord resolves with
    // [
    //   {
    //     id: 1,
    //     type: 'post',
    //     revision: 2
    //   }
    // ]
    store.findRecord('post', '1', { reload: true }).then(function(post) {
      post.revision; // 2
    });
    ```

    If no reload is indicated via the above mentioned ways, then the promise
    immediately resolves with the cached version in the store.

    ### Background Reloading

    Optionally, if `adapter.shouldBackgroundReloadRecord` evaluates to `true`,
    then a background reload is started, which updates the records' data, once
    it is available:

    ```js
    // app/adapters/post.js
    import ApplicationAdapter from "./application";

    export default class PostAdapter extends ApplicationAdapter {
      shouldReloadRecord(store, snapshot) {
        return false;
      },

      shouldBackgroundReloadRecord(store, snapshot) {
        return true;
      }
    });

    // ...

    store.push({
      data: {
        id: 1,
        type: 'post',
        revision: 1
      }
    });

    let blogPost = store.findRecord('post', '1').then(function(post) {
      post.revision; // 1
    });

    // later, once adapter#findRecord resolved with
    // [
    //   {
    //     id: 1,
    //     type: 'post',
    //     revision: 2
    //   }
    // ]

    blogPost.revision; // 2
    ```

    If you would like to force or prevent background reloading, you can set a
    boolean value for `backgroundReload` in the options object for
    `findRecord`.

    ```app/routes/post/edit.js
    export default class PostEditRoute extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, { backgroundReload: false });
      }
    }
    ```

    If you pass an object on the `adapterOptions` property of the options
    argument it will be passed to your adapter via the snapshot

    ```app/routes/post/edit.js
    export default class PostEditRoute extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, {
          adapterOptions: { subscribe: false }
        });
      }
    }
    ```

    ```app/adapters/post.js
    import MyCustomAdapter from './custom-adapter';

    export default class PostAdapter extends MyCustomAdapter {
      findRecord(store, type, id, snapshot) {
        if (snapshot.adapterOptions.subscribe) {
          // ...
        }
        // ...
      }
    }
    ```

    See [peekRecord](../methods/peekRecord?anchor=peekRecord) to get the cached version of a record.

    ### Retrieving Related Model Records

    If you use an adapter such as Ember's default
    [`JSONAPIAdapter`](/ember-data/release/classes/JSONAPIAdapter)
    that supports the [JSON API specification](http://jsonapi.org/) and if your server
    endpoint supports the use of an
    ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
    you can use `findRecord()` or `findAll()` to automatically retrieve additional records related to
    the one you request by supplying an `include` parameter in the `options` object.

    For example, given a `post` model that has a `hasMany` relationship with a `comment`
    model, when we retrieve a specific post we can have the server also return that post's
    comments in the same request:

    ```app/routes/post.js
    export default class PostRoute extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, { include: ['comments'] });
      }
    }
    ```

    ```app/adapters/application.js
    export default class Adapter {
      findRecord(store, schema, id, snapshot) {
        let type = schema.modelName;

        if (type === 'post')
          let includes = snapshot.adapterOptions.include;

          return fetch(`./posts/${postId}?include=${includes}`)
            .then(response => response.json())
        }
      }

      static create() {
        return new this();
      }
    }
    ```

    In this case, the post's comments would then be available in your template as
    `model.comments`.

    Multiple relationships can be requested using an `include` parameter consisting of a
    list of relationship names, while nested relationships can be specified
    using a dot-separated sequence of relationship names. So to request both the post's
    comments and the authors of those comments the request would look like this:

    ```app/routes/post.js
    export default class PostRoute extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, { include: ['comments','comments.author'] });
      }
    }
    ```

    ### Retrieving Specific Fields by Type

    If your server endpoint supports the use of a ['fields' query parameter](https://jsonapi.org/format/#fetching-sparse-fieldsets),
    you can use pass those fields through to your server.  At this point in time, this requires a few manual steps on your part.

    1. Implement `buildQuery` in your adapter.

    ```app/adapters/application.js
    buildQuery(snapshot) {
      let query = super.buildQuery(...arguments);

      let { fields } = snapshot.adapterOptions;

      if (fields) {
        query.fields = fields;
      }

      return query;
    }
    ```

    2. Then pass through the applicable fields to your `findRecord` request.

    Given a `post` model with attributes body, title, publishDate and meta, you can retrieve a filtered list of attributes.

    ```app/routes/post.js
    export default class extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, { adapterOptions: { fields: { post: 'body,title' } });
      }
    }
    ```

    Moreover, you can filter attributes on related models as well. If a `post` has a `belongsTo` relationship to a user,
    just include the relationship key and attributes.

    ```app/routes/post.js
    export default class extends Route {
      model(params) {
        return this.store.findRecord('post', params.post_id, { adapterOptions: { fields: { post: 'body,title', user: 'name,email' } });
      }
    }
    ```

    @since 1.13.0
    @method findRecord
    @public
    @param {String|object} type - either a string representing the name of the resource or a ResourceIdentifier object containing both the type (a string) and the id (a string) for the record or an lid (a string) of an existing record
    @param {(String|Integer|Object)} id - optional object with options for the request only if the first param is a ResourceIdentifier, else the string id of the record to be retrieved
    @param {Object} [options] - if the first param is a string this will be the optional options for the request. See examples for available options.

    pushed manually into the store.

    See [findRecord](../methods/findRecord?anchor=findRecord) if you would like to request this record from the backend.

    _Note: This is a synchronous method and does not return a promise._

    **Example 1**

    `peekRecord` can be called with a single identifier argument instead of the combination
    of `type` (modelName) and `id` as separate arguments. You may recognize this combo as
    the typical pairing from [JSON:API](https://jsonapi.org/format/#document-resource-object-identification)

    If you have previously received an lid from an Identifier for this record, you can lookup the record again using
    just the lid.

    This method makes a request for one record, where the `id` is not known
    beforehand (if the `id` is known, use [`findRecord`](../methods/findRecord?anchor=findRecord)
    instead).

    This method can be used when it is certain that the server will return a
    single object for the primary data.

    Each time this method is called a new request is made through the adapter.

    Let's assume our API provides an endpoint for the currently logged in user
    via:

    ```
    // GET /api/current_user
    {
      user: {
        id: 1234,
        username: 'admin'
      }
    }
    ```

    Since the specific `id` of the `user` is not known beforehand, we can use
    `queryRecord` to get the user:

    ```javascript
    store.queryRecord('user', {}).then(function(user) {
      let username = user.username;
      // do thing
    });
    ```

    The request is made through the adapters' `queryRecord`:

    ```app/adapters/user.js
    import Adapter from '@ember-data/adapter';
    import $ from 'jquery';

    export default class UserAdapter extends Adapter {
      queryRecord(modelName, query) {
        return $.getJSON('/api/current_user');
      }
    }
    ```

    Note: the primary use case for `store.queryRecord` is when a single record
    is queried and the `id` is not known beforehand. In all other cases
    `store.query` and using the first item of the array is likely the preferred
    way:

    ```
    // GET /users?username=unique
    {
      data: [{
        id: 1234,
        type: 'user',
        attributes: {
          username: "unique"
        }
      }]
    }
    ```

    ```javascript
    store.query('user', { username: 'unique' }).then(function(users) {
      return users.firstObject;
    }).then(function(user) {
      let id = user.id;
    });
    ```

    This method returns a promise, which resolves with the found record.

    If the adapter returns no data for the primary data of the payload, then
    `queryRecord` resolves with `null`:

    ```
    // GET /users?username=unique
    {
      data: null
    }
    ```

    ```javascript
    store.queryRecord('user', { username: 'unique' }).then(function(user) {
       // user is null
    });
    ```

  /**
    `findAll` asks the adapter's `findAll` method to find the records for the
    given type, and returns a promise which will resolve with all records of
    this type present in the store, even if the adapter only returns a subset
    of them.

    ```app/routes/authors.js
    export default class AuthorsRoute extends Route {
      model(params) {
        return this.store.findAll('author');
      }
    }
    ```

    _When_ the returned promise resolves depends on the reload behavior,
    configured via the passed `options` hash and the result of the adapter's
    `shouldReloadAll` method.

    ### Reloading

    If `{ reload: true }` is passed or `adapter.shouldReloadAll` evaluates to
    `true`, then the returned promise resolves once the adapter returns data,
    regardless if there are already records in the store:

    ```js
    store.push({
      data: {
        id: 'first',
        type: 'author'
      }
    });

    // adapter#findAll resolves with
    // [
    //   {
    //     id: 'second',
    //     type: 'author'
    //   }
    // ]
    store.findAll('author', { reload: true }).then(function(authors) {
      authors.getEach('id'); // ['first', 'second']
    });
    ```

    If no reload is indicated via the above mentioned ways, then the promise
    immediately resolves with all the records currently loaded in the store.

    ### Background Reloading

    Optionally, if `adapter.shouldBackgroundReloadAll` evaluates to `true`,
    then a background reload is started. Once this resolves, the array with
    which the promise resolves, is updated automatically so it contains all the
    records in the store:

    ```app/adapters/application.js
    import Adapter from '@ember-data/adapter';

    export default class ApplicationAdapter extends Adapter {
      shouldReloadAll(store, snapshotsArray) {
        return false;
      },

      shouldBackgroundReloadAll(store, snapshotsArray) {
        return true;
      }
    });

    // ...

    store.push({
      data: {
        id: 'first',
        type: 'author'
      }
    });

    let allAuthors;
    store.findAll('author').then(function(authors) {
      authors.getEach('id'); // ['first']

      allAuthors = authors;
    });

    // later, once adapter#findAll resolved with
    // [
    //   {
    //     id: 'second',
    //     type: 'author'
    //   }
    // ]

    allAuthors.getEach('id'); // ['first', 'second']
    ```

    If you would like to force or prevent background reloading, you can set a
    boolean value for `backgroundReload` in the options object for
    `findAll`.

    ```app/routes/post/edit.js
    export default class PostEditRoute extends Route {
      model() {
        return this.store.findAll('post', { backgroundReload: false });
      }
    }
    ```

    If you pass an object on the `adapterOptions` property of the options
    argument it will be passed to you adapter via the `snapshotRecordArray`

    ```app/routes/posts.js
    export default class PostsRoute extends Route {
      model(params) {
        return this.store.findAll('post', {
          adapterOptions: { subscribe: false }
        });
      }
    }
    ```

    ```app/adapters/post.js
    import MyCustomAdapter from './custom-adapter';

    export default class UserAdapter extends MyCustomAdapter {
      findAll(store, type, sinceToken, snapshotRecordArray) {
        if (snapshotRecordArray.adapterOptions.subscribe) {
          // ...
        }
        // ...
      }
    }
    ```

    See [peekAll](../methods/peekAll?anchor=peekAll) to get an array of current records in the
    store, without waiting until a reload is finished.

    ### Retrieving Related Model Records

    If you use an adapter such as Ember's default
    [`JSONAPIAdapter`](/ember-data/release/classes/JSONAPIAdapter)
    that supports the [JSON API specification](http://jsonapi.org/) and if your server
    endpoint supports the use of an
    ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
    you can use `findAll()` to automatically retrieve additional records related to
    those requested by supplying an `include` parameter in the `options` object.

    For example, given a `post` model that has a `hasMany` relationship with a `comment`
    model, when we retrieve all of the post records we can have the server also return
    all of the posts' comments in the same request:

    ```app/routes/posts.js
    export default class PostsRoute extends Route {
      model() {
        return this.store.findAll('post', { include: ['comments'] });
      }
    }
    ```
    Multiple relationships can be requested using an `include` parameter consisting of a
    list or relationship names, while nested relationships can be specified
    using a dot-separated sequence of relationship names. So to request both the posts'
    comments and the authors of those comments the request would look like this:

    ```app/routes/posts.js
    export default class PostsRoute extends Route {
      model() {
        return this.store.findAll('post', { include: ['comments','comments.author'] });
      }
    }
    ```

    See [query](../methods/query?anchor=query) to only get a subset of records from the server.

  /**
    Push some data for a given type into the store.

    This method expects normalized [JSON API](http://jsonapi.org/) document. This means you have to follow [JSON API specification](http://jsonapi.org/format/) with few minor adjustments:
    - record's `type` should always be in singular, dasherized form
    - members (properties) should be camelCased

    [Your primary data should be wrapped inside `data` property](http://jsonapi.org/format/#document-top-level):

    ```js
    store.push({
      data: {
        // primary data for single record of type `Person`
        id: '1',
        type: 'person',
        attributes: {
          firstName: 'Daniel',
          lastName: 'Kmak'
        }
      }
    });
    ```

    [Demo.](http://ember-twiddle.com/fb99f18cd3b4d3e2a4c7)

    `data` property can also hold an array (of records):

    ```js
    store.push({
      data: [
        // an array of records
        {
          id: '1',
          type: 'person',
          attributes: {
            firstName: 'Daniel',
            lastName: 'Kmak'
          }
        },
        {
          id: '2',
          type: 'person',
          attributes: {
            firstName: 'Tom',
            lastName: 'Dale'
          }
        }
      ]
    });
    ```

    [Demo.](http://ember-twiddle.com/69cdbeaa3702159dc355)

    There are some typical properties for `JSONAPI` payload:
    * `id` - mandatory, unique record's key
    * `type` - mandatory string which matches `model`'s dasherized name in singular form
    * `attributes` - object which holds data for record attributes - `attr`'s declared in model
    * `relationships` - object which must contain any of the following properties under each relationships' respective key (example path is `relationships.achievements.data`):
      - [`links`](http://jsonapi.org/format/#document-links)
      - [`data`](http://jsonapi.org/format/#document-resource-object-linkage) - place for primary data
      - [`meta`](http://jsonapi.org/format/#document-meta) - object which contains meta-information about relationship

    For this model:

    ```app/models/person.js
    import Model, { attr, hasMany } from '@ember-data/model';

    export default class PersonRoute extends Route {
      @attr('string') firstName;
      @attr('string') lastName;

      @hasMany('person') children;
    }
    ```

    To represent the children as IDs:

    ```js
    {
      data: {
        id: '1',
        type: 'person',
        attributes: {
          firstName: 'Tom',
          lastName: 'Dale'
        },
        relationships: {
          children: {
            data: [
              {
                id: '2',
                type: 'person'
              },
              {
                id: '3',
                type: 'person'
              },
              {
                id: '4',
                type: 'person'
              }
            ]
          }
        }
      }
    }
    ```

    [Demo.](http://ember-twiddle.com/343e1735e034091f5bde)

    To represent the children relationship as a URL:

    ```js
    {
      data: {
        id: '1',
        type: 'person',
        attributes: {
          firstName: 'Tom',
          lastName: 'Dale'
        },
        relationships: {
          children: {
            links: {
              related: '/people/1/children'
            }
          }
        }
      }
    }
    ```

    If you're streaming data or implementing an adapter, make sure
    that you have converted the incoming data into this form. The
    store's [normalize](../methods/normalize?anchor=normalize) method is a convenience
    helper for converting a json payload into the form Ember Data
    expects.

    ```js
    store.push(store.normalize('person', data));
    ```

    This method can be used both to push in brand new
    records, as well as to update existing records.

    @method push
    @public
    @param {Object} data
    @return the record(s) that was created or
      updated.
