javascript - SequelizeJS 映射在第 1000 个循环处停止

Question

此代码需要循环遍历数组中的 1050 个项目，并填充 postgres 数据库中的产品表。不幸的是，它停在 1000 处，没有错误。有谁知道为什么会发生这种情况？

import data from './data';

const Sequelize = require('sequelize');
const sequelize = new Sequelize('graphql', 'billy', '', {
  host: 'localhost',
  dialect: 'postgres',
  operatorsAliases: false,

  pool: {
    max: 5,
    min: 0,
    acquire: 30000,
    idle: 10000
  }
});

sequelize
  .authenticate()
  .then(() => {
    console.log('Connection has been established successfully.');
  })
  .catch(err => {
    console.error('Unable to connect to the database:', err);
  });

const Data = sequelize.define('data', {
  name: Sequelize.TEXT,
});

// force: true will drop the table if it already exists
Data.sync({ force: true })
  .then(() => {
    return data.map(d => {
      return Data.create({
        name: d.name,
      });
    });
  });

您可以使用Model.bulkCreate函数代替Model.create

Data.sync({force: true})
    .then(() => {
        const dataList = data.map( d => { name: d.name});
        return Data.bulKCreate(dataList).then( result => result);
    });
