WorkerGlass provides optional timeout and after failure (reentrancy) for background processing worker engines (like Sidekiq, Resque, etc).
If you don't know what is reentrancy, you can read about it here.
If you want to use timeout and/or reentrancy, please add appropriate modules into your worker.
WorkerGlass allows to configure following options:
| Method | Arguments | Description |
|---|---|---|
| self.logger= | Logger | Set logger which will be used by Worker Glass (if not defined, null logger will be used) |
WorkerGlass has few submodules that you can prepend to your workers to obtain given functionalities:
| Module | Description |
|---|---|
| WorkerGlass::Reentrancy | Provides additional reentrancy layer if anything goes wrong |
| WorkerGlass::Timeout | Allows to set a timeout after which a given worker task will fail |
If you want to provide timeouts for your workers, just prepend WorkerGlass::Timeout to your worker and set the timeout value:
class Worker2
prepend WorkerGlass::Timeout
self.timeout = 60 # 1 minute timeout
def perform(first_param, second_param, third_param)
SomeService.new.process(first_param, second_param, third_param)
end
end
Worker2.perform_async(example1, example2, example3)If you want to provide reentrancy for your workers, just prepend WorkerGlass::Reentrancy to your worker and define after_failure method that will be executed upon failure:
class Worker3
prepend WorkerGlass::Reentrancy
def perform(first_param, second_param, third_param)
SomeService.new.process(first_param, second_param, third_param)
end
def after_failure(first_param, second_param, third_param)
SomeService.new.reset_state(first_param, second_param, third_param)
end
end
