 **For a more robust background job solution, please consider using AWS SQS with the [Lambdakiq](https://github.com/customink/lambdakiq) gem. A drop-in replacement for [Sidekiq](https://github.com/mperham/sidekiq) when running Rails in AWS Lambda using the [Lamby](https://lamby.custominktech.com/) gem.**
