I've missed "find_in_batches" function. The code it's much cleaner now. :) Thank you, <a href="http://mitchellhashimoto.com/" rel="nofollow">Mitchell</a>! Great.

For example, your solution 4 could more easily be done like this: Book.find_in_batches(:batch_size => 100) do |results| # Do something with results end (or view http://gist.github.com/178369) Hey Vitalie,

Great post but a better solution would be to use the ActiveRecord batching methods. For example, your solution 4 could more easily be done like this:

Book.find_in_batches(:batch_size => 100) do |results|
# Do something with results
end
