Rails 5.0 is without a doubt a great release with plenty of useful changes and additions. The most notable change was probably ActionCable - the layer responsible for integrating your app with websockets.

Soft delete is a pretty common feature in most of the applications. It may increase complexity of the queries, nevertheless, not deleting anything might be a right default as the data might prove to be useful in the future: for restoring if a record was removed by mistake, to derive some conclusions based on statistics and plenty of other purposes.

But how exactly does it work? What are the requirements for adding new queue adapters? What kind of API does ActiveJob provide? Let’s dive deep into the codebase and answer these and some other questions.
