A Ruby gem providing ActiveRecord batch methods for plucking columns, reducing SQL queries and memory usage by up to 50%.
What is pluck_in_batches?
PluckInBatches is a Ruby gem that adds `pluck_each` and `pluck_in_batches` methods to ActiveRecord for efficiently batch-processing selected database columns. It solves performance issues when iterating over large datasets by reducing SQL queries and memory usage by up to 50% compared to manual combinations of `in_batches` and `pluck`.
Ruby on Rails developers working with large ActiveRecord datasets who need to optimize memory usage and query performance during batch operations.
Developers choose PluckInBatches because it provides a clean, ActiveRecord-native API for efficient column plucking in batches, delivering measurable performance improvements without complex workarounds.
