How can I use Sequelize's bulkCreate method effectively?

Can you explain how to use Sequelize's bulkCreate method?

Sure! Sequelize's bulkCreate method allows you to insert multiple records into the database in a single query. This is more efficient than inserting records one by one.

What are some examples of using bulkCreate?

Here are a couple of examples: 1. You can pass an array of objects to bulkCreate, like this: Model.bulkCreate([{name: 'John'}, {name: 'Jane'}]); 2. You can also specify options like returning: true to get the created instances back.

Are there any limitations or things to watch out for?

Yes, be cautious with validation and constraints. If one record fails validation, the entire operation may fail. You can use ignoreDuplicates: true to skip duplicates.

Can I use bulkCreate with transactions?

Absolutely! You can wrap bulkCreate in a transaction to ensure that all operations succeed or fail together. Just pass the transaction object as an option.
