Re: creating a virtual file
Take a look how you can hook File calls. https://github.com/pirj/distributed-shelf If you figure out the file is read orr written, you can fetch/update your DB, or redis as suggested.

upload local gem files
hi, guys. please let me know how to upload my app to heroku.. I'm tring to upload my rails app but I'm facing an error saying Could not find gem_file in any of the resources. In fact, I use a gem file not listed on http://rubygems.org/. Does Heroku only allow us to upload gem files ( Gemfile ) of http://rubygems.org/? Can I use my gem fileof local enviornment?

Question on shutting down Workers
Hi - I'm rigging up my own auto-scaling solution for workers. My plan to shut a worker down when it's not needed is to set $exit = true when there are no jobs left for it to do. As you can see (https:// github.com/collectiveidea/delayed_job/blob/v2.1.3/lib/delayed/ worker.rb#L74-92) this will simply end the rake jobs:work task just as if I had (for example) hit Ctrl+C. My question is, will Heroku recognize that the worker process has ended and stop charging my account when this happens? Or do I have to actually hit the Heroku API to shut it down? I'd prefer to use $exit if possible, since that will ensure that the current worker (the one with no jobs available) shuts down, whereas if I tell the Heroku API to decrement my worker count by 1, and I have multiple workers running, it could kill one of the other ones mid-job.

Re: Download rate 260 KB/s
I believe the charges for an additional dyno(s) are usage based so it would be a relatively cheap experiment to add a dyno and do a test. I could be wrong in that there may be some flat charge in going from a free plan to a paid but I don't remember that being the case - it would be documented somewhere on the Heroku site. So add a dyno check the dl rates and then remove the dyno or better yet keep it in place for a month and enjoy the immediate response vs the delayed response of a first page hit (after an idle period of some minutes) while the single dyno spins up. A paid plan keeps the dynos spinning and available. On Jan 25, 11:46 am, obruening ollibruen...@googlemail.com wrote: I have a rails app installed on Heroku. It uses the 1 dyno free plan.

Re: Understanding DATABASE_URL vs. SHARED_DATABASE_URL
the SHARED_DATABASE_URL is set because all apps on Heroku come with a share database. It is not used by itself. The DATABASE_URL is the URL used by all tools. You can ignore the SHARED_DATABASE_URL in this case.

Automated database backups to S3 using AWS-S3 gem
I'm already familiar with another solution for automatically backing up your Heroku database to S3 using the fog gem called bakkuappu.

Re: rake db:migrate appeared to start migrating from the very beginning on two different apps.
This happened again to me. I verified that: - the schema_migrations table was full of data - that a Gemfile change didn't prompt this. For whatever it's worth, here is the relevant portion of my Ruby script for pushing my app to heroku: #Push to Heroku system 'git push heroku' #Migrate the DB for the main application system 'heroku rake db:migrate' I have the DB backups in place to recover from this, but it is very disconcerting. I'm trying to think of a reason why the schema_migrations table might not be available after the 'git push heroku' call. Should I make the script sleep for a couple of seconds?
