I'm struggling to figure out how to set the

state_backend

uniquely per environment. for instance, this works:

version: 1
project_id: blah
default_environment: dev
state_backend:
  uri: 'file:///${MELTANO_SYS_DIR_ROOT}/state'

I expecte the following to work, but this does not:

version: 1
project_id: blah
default_environment: dev
environments:
  - name: dev
    config:
      state_backend:
        uri: 'file:///${MELTANO_SYS_DIR_ROOT}/state'

I solved this by setting the backend to a env variable like this

state_backend:
  uri: $MELTANO_STATE_BUCKET

so when I develop and want to run locally I set it to

file:///project/$state_dir

and in production I set it to

<gs://meltano-state-bucket>

yeah, i have a similar solution as well, but i find this less explicit than having it be specified in the meltano.yml file.

Project-level settings are not supported at the environment level, unfortunately. Do log an issue if you really need it, though.

I see, I think I'll create an issue to improve the documentation to highlight this limitation, and take it on myself 🙂
