Firefly is a little distributed app to load transactions from a custom configured cloud provider and load it to a local (or cloud) elastic instance. It is a demo app to demonstrate how this could be done.

• Model the domain using the Algebraic Type System in scala
• Make the domain model serve as design documentation
• Make the design documentation compilable - so it doesnt get out-of-sync with the implementation
• Make the domain model readable by domain experts

components:

domain:

bounded contexts:

modules:

fetch transactions:

run etl:

• layers are io, service and domain
• io is infrastructure, REST api and serializers
• service is wired in beans that invoke workflows
• domain is types (domain model) and workflow implementations

• On Linux (tested on Ubuntu 18.04.5 LTS)
