title: How to do Bulk insert using Sequelize and node.js
body: <p>js + sequelize to insert 280K rows of data using JSON.
  The JSON is an array of 280K. Is there a way to do bulk insert in chunks. I am seeing that it takes a lot of time to update the data. When i tried to cut down the data to 40K rows it works quick. Am i taking the right approach. Please advice. I am using postgresql as backend.</p>
  
  <pre><code>PNs.bulkCreate(JSON_Small)
          .catch(function(err) {
              console.log('Error ' + err);
          })
          .finally(function(err) {
              console.log('FINISHED  + ' \n +++++++ \n');
  
          });
  </code></pre>
