On another project, there’s a has_many association on a table with 40,000 records in MySQL. It seems that pulling these in through standard ActiveRecord means is not releasing memory (you can watch the memory grow as it executes). The work around was to use ActiveRecord::Base.connection.select_all(), but it would be nice to know why GC didn’t kick in and clean up house. Maybe AR is holding on to object references somewhere outside of scope?
