target-gcs is a Singer target for GCS.

Build with the Meltano Target SDK.

• Developer TODO: Update the below as needed to correctly describe the install procedure. For instance, if you do not have a PyPi repo, or if you want users to directly install from your git repo, you can modify this step as appropriate.

pipx install target-gcs

JSONL and CSV are two supported output formats

| file_format | TARGET_GCS_FILE_FORMAT | string | no | jsonl | File format to be used. Currently supports jsonl and csv

Property Type Required? Description aws_access_key_id String No S3 Access Key Id. If not provided, AWS_ACCESS_KEY_ID environment variable will be used. aws_secret_access_key String No S3 Secret Access Key. If not provided, AWS_SECRET_ACCESS_KEY environment variable will be used.

A full list of supported settings and capabilities for this target is available by running:

target-gcs --about

This Singer target 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.

• Developer TODO: If your target requires special access on the source system, or any special authentication requirements, provide those here.

You can easily run target-gcs by itself or in a pipeline using Meltano.

target-gcs --version
target-gcs --help
# Test using the "Carbon Intensity" sample:
tap-carbon-intensity | target-gcs --config /path/to/target-gcs-config.json

pipx install poetry
poetry install

Create tests within the target_gcs/tests subfolder and then run:

poetry run pytest

You can also test the target-gcs CLI interface directly using poetry run:

poetry run target-gcs --help

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

Your project comes with a custom meltano.yml project file already created. Open the meltano.yml and follow any "TODO" items listed in the file.

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

# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd target-gcs
meltano install

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke target-gcs --version
# OR run a test `elt` pipeline with the Carbon Intensity sample tap:
meltano elt tap-carbon-intensity target-gcs

See the dev guide for more instructions on how to use the Meltano SDK to develop your own Singer taps and targets.
