More efficient find_in_batches for Algolia + Mongoid

algolia_mongoid_batch_find.rb

module AlgoliaMongoidBatchFind
  # more efficient than the built-in adapter for bulk reindexing (mongoid adapter)
  def algolia_find_in_batches(options={}, &block)
    options[:batch_size] ||= 100
    offset = 0
    offset.step(Product.count, options[:batch_size]) do |offset|
      yield Product.limit(options[:batch_size]).skip(offset).to_a
    end
