Overview

A trigger based on the RufusTrigger, runs the PollingHandler at the given timing. The handler calls the scheduler's method with a block which compares the yield result with the previous one. If they are different, yield returns true:

trigger :my_database, :polling, interval: "1min" def check_timestamp(db) # will perform MyJob if the name have changed return unless yield(db[:items].select(:name).first)

MyJob.perform_later

end
