Delaying the process may only be wanted if a specific threshold of CO2e reduction is possible.

Describe the solution you'd like

• Allow setting a minimal amount of g/CO2 per kWh which should be saved at least
• Think about a retry logic

Additional context
none

To measure the possible impact without the shifting intervention, we add a mode to collect data only.

Describe the solution you'd like
The measurement mode should not time shift the process, it should just collect the data. Using the data, you can analyze the impact time shifting has on your business process.

Additional context
Measuring the impact first offers a better basis for argumentation.

Incident are not handled equally in C7 and C8: In C7 exceptions are catched in C8 not.

Describe the solution you'd like

• unify incident handling for C7 / C8
• potentially add input whether Carbon Reductor errors should be returned to the process

Additional context

If the version change doesn't cause issues, please update the Carbon Aware SDK image version in the docker-compose file.
If the API changes adopt the API client.

We would like to use the Connector SDK as Runtime instead of a JobWorker.

Describe the solution you'd like
As soon as https://github.com/camunda/connector-sdk/issues/180 is implemented we can use that to reschedule the invocation.

Hello friends of Camunda and the planet, I hope this message finds you well!

I follow these documents step by step:
camunda-carbon-reductor-c8
AND
api-carbon-aware

I was able to create the user on watttime.org and generate the token through login.

I made the changes indicated in docker-compose as follows:
docker-compose.yaml

I uploaded docker with docker-compose up and tested:
http://localhost:8090/emissions/forecasts/current?location=westus
It's working correctly.

However, the connector is giving an incident:
Expected to throw an error event with the code 'carbon-reductor-error' with message 'Could not query API to get infos about future emissions', but it was not caught. No error events are available in the scope.

In the camunda-8-carbon-reductor-connector docker console:

I'd like to know what's wrong.

Is your feature request related to a problem? Please describe.
To reduce the resource usage of the worker we should ahead-of-time compile our applications with GraalVM.

Describe the solution you'd like
We're compiling the worker to a native image using GraalVM (Docker multi-stage build maybe).
Also have a look at building a custom JDK distribution (jlink) for smaller target images.

Goal is to optimize resource usage and reduce startup time as well as memory consumption.

Additional context
By switching to GraalVM we can consider using Micronaut as framework.

Have a look at the Spring and other dependencies as well.

Update GitHub Actions to use Node 20 according to the following blogpost:
https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/

Describe the bug

ERROR: Multiple platforms feature is currently not supported for docker driver. Please switch to a different driver (eg. "docker buildx create --use")

See: https://github.com/envite-consulting/camunda-carbon-reductor/actions/runs/5690641292/job/15424376716

Expected behavior
Build and publish für multiple architectures.

Environment (please complete the following information):

• GitHub Actions only

Additional context
Possible opportunities would:

• docker/build-push-action#302 (comment)
• https://github.com/docker/setup-buildx-action#inputs

The variables and domain class names could be improved to be easier to catch.

Describe the solution you'd like
Improved variable and class names, mainly in the core-module.
