Pluck_in_batches

Overview

If you're working with large datasets in Ruby on Rails, chances are you've experienced the challenges of processing records efficiently. Enter the "PluckInBatches" gem — a powerful tool designed to enhance ActiveRecord's capabilities for batch processing. By leveraging ActiveRecord's existing find and pluck methods, this gem enables seamless retrieval of specific fields without the need to load entire records into memory. Ideal for optimizing performance, it allows you to handle large data efficiently, making it a game-changer for developers focused on enhancing application responsiveness.

With performance improvements that can be up to twice as fast as traditional methods, PluckInBatches is a must-have for developers dealing with extensive databases. Its intelligent handling of SQL queries and memory allocation makes it an essential addition to any Ruby on Rails project, particularly those on Ruby 2.7 and above with ActiveRecord 6 or greater.
