ūüöÄ Ruby Tip: Maximizing Efficiency large set of records with`find_each`

In Ruby on Rails application development, efficiently handling large datasets is crucial for your application's performance. In this context, the `find_each` method emerges as a powerful tool that many developers underestimate.

What is the `find_each` method?

The `find_each` is a method available in Ruby on Rails' ActiveRecord that allows you to process large sets of records more efficiently than the traditional `each`. Instead of loading all records into memory at once, `find_each` processes records in predefined batches, which can save memory and improve your application's performance.

Advantages of `find_each`

- Memory Savings: By processing records in batches, `find_each` avoids the memory overhead that can occur when using `each` on very large datasets.

- Improved Performance: Since `find_each` processes records in batches, it is more performance-efficient, especially with extensive datasets.

- Prevents Timeouts: In operations involving a large number of records, using `find_each` can help prevent timeouts due to processing smaller batches.

When to Use `find_each`

`find_each` is particularly useful when dealing with large data volumes, such as background tasks, bulk data imports, or processing records in large database tables. It is a recommended practice whenever you are handling extensive datasets to optimize your application's performance.

In conclusion, the `find_each` method in Ruby on Rails is a powerful tool that can significantly enhance the efficiency and performance of your application when handling large datasets. By incorporating this method into your code, you are taking proactive steps to optimize how your application processes and manipulates data, resulting in a faster and more efficient experience for your users.
