I got a little bit further. I could make Rails sleep for just a few
milliseconds between executing the threads of course. It's not pretty
though. If anyone knows of a better way, please tell me!
Will the following give me any problems? I can imagine ActiveRecord
could clot up when some of the threads write at the same time, or
won't I have to worry about that?
Worker FooBar
def scheduler(queries_per_minute, collection)
sleeptime = 60 / queries_per_minute
collection.each do |item|
Thread.new do
executor(collection)
sleep sleeptime
end
end
end
def executor
#execute request
end
end
Thank you!
