I am trying to optimize my Rails code for database inserts. I often
have to insert/update several thousand records after web crawls. Once
I have all the data to insert/update, what are some good ways to
optimize this? I've looked into doing multiple inserts using object-
level transactions. However, the Rails API states that this
functionality is deprecated (http://api.rubyonrails.org/classes/
ActiveRecord/Transactions/ClassMethods.html#M000681). What is the
preferred method? Thanks!
