@cicoyle thoughts on making this a tutorial since its multi-language?? We already have a good set of tutorials from Marc for Dapr university and could add it here: https://github.com/dapr/quickstarts/tree/master/tutorials/workflow |
|
I'm not able to review here but the current makefile commands require SDKMAN. You can update it to not use that and it works, or you need to add it as a dependency Looks like the go sdk version is stale and should be updated from 1.13 |

Thanks @cicoyle great qs. LMK if you think this one would be a good use case for adding back in the mechanical markdown to ensure correctness on multiapp wfs going forward..

Can we add a link to docs for multi-app workflow stuff?

We need a section maybe here that details the differences between cross app and multi app and when they are used.

Call out what is a cross-app/multi-app call in code comments within the wf

I would prefer to put this particular sample into Samples repo and not into Quickstarts and certainly not under the /workflows folder. This is not a quickstart app, it has multiples language and 2 or 3 apps are sufficient to make the point . Also we have to consider any example to be done in other languages, including .NET. I would prefer to have a single language versions for Java, Go, .NET etc to demo multi-application workflow like over features and keep this simple. |
Added a multi app example including a go and java scenario.
