最好在无服务器的环境中使用apollo服务器lambda和appsync

Question

我在无服务器graphql演示中看到了这样的一段代码

custom:
  accountId: 1234xxxxxxxx # replace this with your accountId
  appSync:
    # name:  # defaults to api
    # apiId # only required for update-appsync
    authenticationType: AMAZON_COGNITO_USER_POOLS # API_KEY is also supported
    userPoolConfig:
      awsRegion: us-east-1 # required # region
      defaultAction: ALLOW
      userPoolId: us-east-1_xxxxxxxxx # replace this with your Cognito User Pool Id
    # region: # defaults to provider region
    # mappingTemplatesLocation: # defaults to mapping-templates
    mappingTemplates:
      - dataSource: Lambda
        type: Query
        field: getUserInfo
        request: "getUserInfo-request-mapping-template.txt"
        response: "getUserInfo-response-mapping-template.txt"
      - dataSource: Lambda
        type: Query
        field: meInfo
        request: "meInfo-request-mapping-template.txt"
        response: "meInfo-response-mapping-template.txt"
      - dataSource: Lambda
        type: Mutation
        field: createTweet
        request: "createTweet-request-mapping-template.txt"
        response: "createTweet-response-mapping-template.txt"
      - dataSource: Lambda
        type: Mutation
        field: deleteTweet
        request: "deleteTweet-request-mapping-template.txt"
        response: "deleteTweet-response-mapping-template.txt"
      - dataSource: Lambda
        type: Mutation
        field: reTweet
        request: "reTweet-request-mapping-template.txt"
        response: "reTweet-response-mapping-template.txt"
    # schema: # defaults schema.graphql
    serviceRole: "AppSyncServiceRole"
    dataSources:
      - type: AWS_LAMBDA
        name: Lambda
        description: 'Lambda DataSource'
        config:
          lambdaFunctionArn: "arn:aws:lambda:us-east-1:${self:custom.accountId}:function:serverless-graphql-appsync-lda-production-graphql"
          serviceRoleArn: "arn:aws:iam::${self:custom.accountId}:role/Lambda-${self:custom.appSync.serviceRole}"
  serverless-offline:
    port: 4000
  webpackIncludeModules: true

functions:
  graphql:
    handler: handler.graphqlHandler
    events:
      - http:
          path: graphql
          method: POST

mappingTemplates下的字段对应于grahql的解析器。这会将每个接口拆分为lambda函数吗？ 该性能优于下面的总体graphql条目？更经济吗？

functions:
  graphql:
    handler: handler.graphqlHandler
    events:
      - http:
          path: graphql
          method: POST

谢谢
