Hi everyone, We have created a first version of the

dagster-ext

a Meltano extension to automatically interface with Dagster. The project is still a work in progress, but it would be great to have some beta testers to collect some first feedback. You can "install" the extension by adding the following yaml to your `meltano.yml`:

plugins:
  utilities:
    - name: dagster
      namespace: dagster
      pip_url: dagster-ext==0.0.1a5 dbt-core dbt-postgres
      executable: dagster_invoker
      settings:
        - name: dagster_home
          env: DAGSTER_HOME
          value: $MELTANO_PROJECT_ROOT/.meltano
          label: The home folder of Dagster
        - name: repository_dir
          env: REPOSITORY_DIR
          value: $MELTANO_PROJECT_ROOT/orchestrate
          label: The root folder of the Dagster project
      commands:
        initialize:
          args: initialize
          executable: dagster_extension
        init:
          args: initialize
          executable: dagster_extension
        up:
          args: -f $REPOSITORY_DIR/repository.py
          executable: dagit_invoker

You can setup the plugin by running

meltano invoke dagster:init

(If you want to use dbt, don't forget to change the dbt plugin above.) (This version doesn't have Singer as Software Defined Assets yet, as Meltano will need some extra cli endpoints to achieve this.)
