I just remember that in the older version of backgroundrb I was having
memory/performance issues until I added self.delete to do_work. Then
those problems went away. My worker is very simple:
class ContextWorker < BackgrounDRb::MetaWorker
set_worker_name :context_worker
pool_size 5
def create(args = nil)
end
def process_context(context_id)
require 'context_update'
@r_update = ContextUpdate.new(Time.now)
@r_update.load_public_context(context_id)
end
end
The bulk of the code is in libraries. So you're saying I self.delete
is the same as putting exit after
@r_update.load_public_context(context_id)?
thanks!
