Question 1

How do I set up Sidekiq.cr in a Crystal project?

Accepted Answer

Check the project's wiki for detailed documentation. Typically, add it as a dependency in shard.yml and configure the Redis connection, similar to Ruby Sidekiq but with Crystal's syntax and type safety.

Question 2

What's the real-world performance boost of Sidekiq.cr vs Ruby Sidekiq?

Accepted Answer

Benchmarks indicate Sidekiq.cr is about 3-4 times faster, processing 26,000 jobs/sec compared to Ruby's 7,900 jobs/sec with hiredis, and uses a third of the memory, making it suitable for high-throughput scenarios.

Question 3

Can Sidekiq.cr work with my existing Ruby Sidekiq job queues?

Accepted Answer

Yes, it maintains Redis data compatibility, so both versions can interoperate seamlessly—you can enqueue jobs in Ruby and process them in Crystal, or vice versa.

Question 4

Does Sidekiq.cr include a web dashboard for monitoring jobs?

Accepted Answer

No, it does not have a built-in web UI like Ruby Sidekiq. You'll need to use Redis CLI tools, logs, or build custom monitoring solutions.

Question 5

How to handle scheduled jobs in Sidekiq.cr since delayed extensions aren't supported?

Accepted Answer

For scheduling, use external cron jobs or a separate scheduler service, as Sidekiq.cr lacks native delayed job support due to Crystal's static typing constraints.

Question 6

Is Sidekiq.cr production-ready for large-scale applications?

Accepted Answer

Yes, with its high performance and stability, it's suitable for production, but ensure proper process management via tools like Systemd since it lacks built-in daemonization.

Question 7

Should I switch from Ruby Sidekiq to Sidekiq.cr for better performance?

Accepted Answer

Switch if you need higher throughput and lower memory usage for CPU-intensive jobs, but stick with Ruby Sidekiq if you rely on features like delayed jobs, web UI, or extensive plugin ecosystems.
