Reactive BBQ Case Study

Some people can learn RIDDL faster by looking at examples than by reading the informal definitions in the language reference or the formal definitions in the EBNF grammar. To support that mode of learning, this section decomposes the domain of a restaurant, Reactive BBQ.

About Reactive BBQ

The Reactive BBQ domain is a familiar one for those who have taken the Lightbend Reactive Architecture Professional (LRA-P) course which uses this example throughout the course to good effect in the workshops. The same premises apply in this domain, but we have chosen to fully specify it in RIDDL.

As you might guess from the name, Reactive BBQ is a restaurant chain that serves spicy (reactive!) BBQ dishes. It doesn't exist of course, even if some people may or may not have mistaken R&R BBQ in Salt Lake City for the Reactive version in 2018.

The Reactive BBQ case study in the LRA-P course included interviews with several fictitious employees. Those interviews and the case study material have been replicated in the scenario description with thanks to Lightbend; we recommend that you read that scenario first.
