I am planning on doing the exact same thing for my periodic tasks. I
think it makes sense so let's make it into a BackgrounDRb best
The thing to keep in mind is each worker gets a Ruby process, which
can consume 20-40 MB of memory. So if you can combine workers it will
definitely save resources. There really isn't a good reason I can
think of to have a bunch of workers sitting around just to be run one
or twice a day. So might as well put them all into one worker.
Especially if you can schedule tasks so they never overlap.
The way to keep this from getting too messy (as in a worker with tons
of unrelated code) is to extract the real work into separate ruby
modules which are required in the worker and then called from the
worker methods. Well that is how I have written things :)
