target-s3 is a Singer target for s3 for writing parquet files to s3. This target uses pyarrow to write data in the parquet format to s3 and no Athena-databases or Glue catalogs are required.
Build with the Meltano Target SDK.
Install from GitHub:
pipx install git+https://github.com/ORG_NAME/target-s3.git@mainA full list of supported settings and capabilities for this target is available by running:
target-s3 --aboutThis 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.
If you are using this tap with an S3 bucket that do not have public access, you need to first create a user and give it necessary access to S3. You then need to generate access keys that this target then will use to authenticate. Always store your credentials in a safe way.
You can easily run target-s3 by itself or in a pipeline using Meltano.
target-s3 --version
target-s3 --help
# Test using the "Carbon Intensity" sample:
tap-carbon-intensity | target-s3 --config /path/to/target-s3-config.jsonTesting with Meltano
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.
Next, install Meltano (if you haven't already) and any needed plugins:
# Install meltano
pipx install meltano
# Initialize meltano within this directory
cd target-s3
meltano installNow you can test and orchestrate using Meltano:
# Test invocation:
meltano invoke target-s3 --version
# OR run a test `elt` pipeline with the Carbon Intensity sample tap:
meltano elt tap-carbon-intensity target-s3See the dev guide for more instructions on how to use the Meltano Singer SDK to develop your own Singer taps and targets.
