Batchr

gem 'batchr'

$ gem install batchr

class ApiSender
  def bulk_send objects = []
    # use some API that allows sending, say, up to 10 objects at once
  end
end

Batchr.batch(ApiSender.new, :bulk_send) do |batchr|
  b.batch_size = 10 # optional; default is 400
  read_really_really_long_csv_file do |row|
    batchr << row
  end
end

I found this useful when I was parsing a large CSV file and storing the results in a DB. The DB was slow to insert the rows individually, and couldn't handle an import the size of the entire file. So, I created Batchr to batch the parsed CSV into the DB.
