benchmark('mongodb vs postgres', () => {
  // initialize a context for benchmark
  setup(async () => {
    const { Client } = await import('pg');
    const postgres = new Client();
    await postgres.connect();

    const { MongoClient } = await import('mongob');
    const mongo = new MongoClient(uri);
    await mongo.connect();

    return { postgres, mongo };
  });

  measure('mongodb inserts', ({ mongo } /* context */, next) => {
    // prepare a collection
    const database = mongo.db('overtake');
    const test = database.collection('test');

    return (data) => test.insertOne(data).then(next);
  });

  measure('postgres inserts', ({ postgres } /* context */, next) => {
    // prepare a query
    const query = 'INSERT INTO overtake(value) VALUES($1) RETURNING *';

    return (data) => postgres.query(query, [data.value]).then(next);
  });

  teardown(async ({ mongo, postgres }) => {
    await postgres.end();
    await mongo.end();
  });

  perform('simple test', 100000, [[{ value: 'test' }]]);
});
