Are there any good examples of how to use the

MELTANO_MAP_TRANSFORMER_STREAM_MAPS

environment variable. Meltano Hub mentions it but it’s not immediately apparent to me what it overwrites because there is a separate

stream_maps

key for each

mapping

in the

meltano.yml

file which begs the question: when I use this variable which mapping is it going to control?

Hey Josh! Does this help?

ah, almost. I’m thinking more along the lines of the way to handle a config like this:

mappers:
  - name: meltano-map-transformer
    variant: meltano
    pip_url: git+<https://github.com/MeltanoLabs/meltano-map-transform.git>
    settings:
    - name: stream_maps
      kind: object
    mappings:
    - name: mapping1
      config:
        stream_maps:
          'foo-bar':
            spam:
    - name: mapping2
      config:
        stream_maps:
          'foo-eggs':
            spam: str(spam)

I see, yeah the env var does not make a distinction between mappings of a single mapper and it's a 🐛 in my opinion. Do log an issue in github.
