Configure using environment variables

This Singer tap will automatically import any environment variables within the working directory's .env if the --config=ENV is provided, such that config values will be considered if a matching environment variable is set either in the terminal context or in the .env file.

Source Authentication and Authorization

tap-superset uses the /api/v1/security/login endpoint to get its Auth Token from superset.

So it is necessary to set the username and password variables for Authentication. The user provided should have access to the superset API and you can create it with the superset cli

Usage

You can easily run tap-superset by itself or in a pipeline using Meltano.

Executing the Tap Directly

tap-superset --version
tap-superset --help
tap-superset --config CONFIG --discover > ./catalog.json

Developer Resources

Follow these instructions to contribute to this project.

Initialize your Development Environment

pipx install poetry
poetry install

Create and Run Tests

Create tests within the tests subfolder and then run:

poetry run pytest

You can also test the tap-superset CLI interface directly using poetry run:

poetry run tap-superset --help

Testing with Meltano

Note: This tap will work in any Singer environment and does not require Meltano. Examples here are for convenience and to streamline end-to-end orchestration scenarios.

Next, install Meltano (if you haven't already) and any needed plugins:

# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd tap-superset
meltano install

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke tap-superset --version
# OR run a test `elt` pipeline:
meltano elt tap-superset target-jsonl
