Round 1

The benchmark

The benchmark consists in a simple blogging GraphQL server:

• fetching json (author profiles) from a remote HTTP server

• reading rows (posts and comments) from a Postgres database

Schema file

type Post {
    author: Author!
    title: String!
    content: String!
    comments: [Comment!]
}

type Comment {
    author: Author!
    post: Post!
    content: String!
}

type Author {
    firstName: String!
    lastName: String!
    bio: String!
    posts: [Post!]
    comments: [Comment!]
}

type Query {
    posts: [Post!]
    author(id: Int!): Author
}

The backend HTTP service is setup with 10 authors.

The Postgres database is setup with:

• 2 posts per author

• 2 comments per post:

  • 1 comment from another author

  • 1 comment (reply) from the post author

Each framework is tested with different queries.

Guidelines

The server must:

• accept the BACKEND_HOST environment variable for configuration

• accept the POSTGRES_HOST environment variable for configuration

The server may:

• cache author profiles per-query

• use HTTP and Postgres pipelining

The server must not:

• cache all posts and comments

• cache all author profiles

Test environment

• 3 quad-core servers Intel Xeon e5-2637v3 128G RAM (injector, server, backend)

• 1 quad-core server Intel Xeon e5-2637v3 256G RAM (postgres)

• 10 GbE switch

Contributing

You can add an implementation in the implementations directory.

Make sure the name describes the software stack. For example, Java/vertx-graphql-java means the implementation:

• is written in the Java language

• uses Vert.x as the web server

• uses GraphQL-Java engine

Each implementation must provide:

• a Dockerfile (build and run)

• a set-env.sh file that defines the FRAMEWORK_NAME implementation (must be unique across implementations)

For testing purposes, you can build and run with Docker:

• the backend server

• the postgres database
