Question 1

goworker vs Sidekiq for Ruby background jobs

Accepted Answer

goworker uses Go for better concurrency and lower resource costs but requires deploying Go workers, while Sidekiq is Ruby-native with more features like retries. Choose goworker if you're tied to Resque and need performance boosts without rewriting job producers.

Question 2

How to handle job arguments in goworker

Accepted Answer

Arguments come as interface{} slices; you must use type assertions to convert them, as shown in the README with json.Number for numeric types. This adds boilerplate code compared to typed systems.

Question 3

What happens if goworker crashes during a job

Accepted Answer

Jobs may be lost, as per the failure modes section. Recovery is manual from Redis under the worker key, but there's no guarantee the job hasn't already finished, making idempotency critical.

Question 4

Can goworker run on Heroku with signal handling

Accepted Answer

Yes, it handles TERM signals gracefully, but jobs must finish within 10 seconds to avoid loss when Heroku sends a KILL signal, as noted in the README's failure modes.

Question 5

How to share database connections in goworker workers

Accepted Answer

Use closures to share resources like database pools, as demonstrated in the README with a function that returns a worker function, allowing variable sharing across multiple jobs.

Question 6

Does goworker support job retries or scheduling

Accepted Answer

No, it inherits Resque's basic model without built-in retries or scheduling; you must implement such features manually in your job logic or use external tools.

Question 7

How to test goworker jobs locally with Redis

Accepted Answer

Use redis-cli to push jobs onto queues, as shown in the README example with RPUSH, simulating job enqueueing from Ruby or Go for debugging and benchmarking.
