Lightweight Message Bus Alternative for Embedded Environments #39
Description
The current Kafka based message bus is a good approach for addressing use cases that address larger installations that also requires the solution to scale. For smaller embedded solutions it generates a too large memory footprint though. For embedded solutions we need something more lightweight. This issue is there to be a container for that type of work. From an agile manner the story would be something like "As an integrator or solution builder I need ODIM to have a lightweight message bus so that ODIM can live in embedded environments"
As a principle we would keep the current APIs that are there to interact with the message bus and by that avoiding changes in any other parts of the code. We would need to introduce some configuration parameter that dictates what message bus technology to use though.
