Question

I want to execute a very long query in Rails using ActiveRecord::Base.connection.execute(sql).

However, the query keeps timing out. Is it possible to change the timeout value for this specific query instead of having to change the timeout value for all queries in database.yml?

Thanks

Answer 1

# in database.yml
production: &prod
  adapter: whatever
  timeout: 5000 

long_connection_production:
  <<: prod
  timeout: 10000

# app/models/long_connection.rb
class LongConnection < ActiveRecord::Base
  establish_connection "long_connection_#{Rails.env}"

  def self.do_thing_that_takes_a_long_time
    connection.execute(sql)
  end
end
