  const client = await Fucker.DbConnector(options).connect();

  // 2 step -> generate fake data for seeding them to our database
  const chunkSize = 10000;
  const chunksCount = 100;
  const dataGenerator = new Fucker.DataGenerator(schema, chunkSize);

  // 3 step -> seed you database 
  console.time('generate items start');
  for (let i = 0; i < chunksCount; i += 1) {
    console.time('chunk');
    console.log(`#${i} chunkSize ${chunkSize}`);

    const itemsChunk = dataGenerator.generate();

    await client.seed(itemsChunk);

    console.timeEnd('chunk');
  }
