fatkodima/pluck_in_batches

ActiveRecord comes with find_each / find_in_batches / in_batches methods to batch process records from a database. ActiveRecord also has the pluck method which allows the selection of a set of fields without pulling the entire record into memory. This gem combines these ideas and provides pluck_each and pluck_in_batches methods to allow batch processing of plucked fields from the database.
