PipelineWise is a Data Pipeline Framework using the Singer.io specification to ingest and replicate data from various sources to various destinations. Documentation is available at https://transferwise.github.io/pipelinewise/

• Built with ELT in mind: PipelineWise fits into the ELT landscape and is not a traditional ETL tool. PipelineWise aims to reproduce the data from the source to an Analytics-Data-Store in as close to the original format as possible. Some minor load time transformations are supported but complex mapping and joins have to be done in the Analytics-Data-Store to extract meaning.

• Managed Schema Changes: When source data changes, PipelineWise detects the change and alters the schema in your Analytics-Data-Store automatically

• Load time transformations: Ideal place to obfuscate, mask or filter sensitive data that should never be replicated in the Data Warehouse

• YAML based configuration: Data pipelines are defined as YAML files, ensuring that the entire configuration is kept under version control

• Lightweight: No daemons or database setup are required

• Extensible: PipelineWise is using Singer.io compatible taps and target connectors. New connectors can be added to PipelineWise with relatively small effort

Tap extracts data from any source and write it to a standard stream in a JSON-based format, and target consumes data from taps and do something with it, like load it into a file, API or database

Type	Name	Extra	Latest Version	Description
Tap	Postgres			Extracts data from PostgreSQL databases. Supporting Log-Based, Key-Based Incremental and Full Table replications
Tap	MySQL			Extracts data from MySQL databases. Supporting Log-Based, Key-Based Incremental and Full Table replications

Transform	Field			Transforms fields from any tap and sends the results to any target. Recommended for data masking/ obfuscation

Note: Extra connectors are experimental connectors and written by community contributors. These connectors are not maintained regularly and not installed by default. To install the extra packages use the --connectors=all option when installing PipelineWise.

If you have Docker installed then using docker is the recommended and easiest method to start using PipelineWise.

1. Build an executable docker image that has every required dependency and is isolated from your host system.

By default, the image will build with all connectors. In order to keep image size small, we strongly recommend you change it to just the connectors you need by supplying the --build-arg command:

```sh
$ docker build --build-arg connectors=tap-mysql,target-snowflake -t pipelinewise:latest .
```

2. Once the image is ready, create an alias to the docker wrapper script:

   $ alias pipelinewise="$(PWD)/bin/pipelinewise-docker"

3. Check if the installation was successful by running the pipelinewise status command:

   $ pipelinewise status
   
   Tap ID    Tap Type      Target ID     Target Type      Enabled    Status    Last Sync    Last Sync Result
   --------  ------------  ------------  ---------------  ---------  --------  -----------  ------------------
   0 pipeline(s)

You can run any pipelinewise command at this point. Tutorials to create and run pipelines is at creating pipelines.

Running tests:

• To run unit tests, follow the instructions in the Building from source section.
• To run integration and unit tests, follow the instructions in the Developing with Docker section.

1. Make sure that all dependencies are installed on your system:

   • Python 3.x
   • python3-dev
   • python3-venv
   • mongo-tools
   • mbuffer

2. Run the install script that installs the PipelineWise CLI and all supported singer connectors into separate virtual environments:

   $ ./install.sh --connectors=all

   Press Y to accept the license agreement of the required singer components. To automate the installation and accept every license agreement run ./install --acceptlicenses Use the optional --connectors=...,... argument to install only a specific list of singer connectors.

3. To start the CLI you need to activate the CLI virtual environment and set PIPELINEWISE_HOME environment variable:

   $ source {ACTUAL_ABSOLUTE_PATH}/.virtualenvs/pipelinewise/bin/activate
   $ export PIPELINEWISE_HOME={ACTUAL_ABSOLUTE_PATH}

   (The ACTUAL_ABSOLUTE_PATH differs on every system, the install script prints the correct commands once the installation completes)

4. Check if the installation was successful by running the pipelinewise status command:

   $ pipelinewise status
   
   Tap ID    Tap Type      Target ID     Target Type      Enabled    Status    Last Sync    Last Sync Result
   --------  ------------  ------------  ---------------  ---------  --------  -----------  ------------------
   0 pipeline(s)

You can run any pipelinewise command at this point. Tutorials to create and run pipelines can be found here: creating pipelines.

To run unit tests:

$ pytest --ignore tests/end_to_end

To run unit tests and generate code coverage:

$ coverage run -m pytest --ignore tests/end_to_end && coverage report

To generate code coverage HTML report.

$ coverage run -m pytest --ignore tests/end_to_end && coverage html -d coverage_html

Note: The HTML report will be generated in coverage_html/index.html

To run integration and end-to-end tests:

To run integration and end-to-end tests you need to use the Docker Development Environment. This will spin up a pre-configured PipelineWise project with pre-configured source and target databases in several docker containers which is required for the end-to-end test cases.

If you have Docker and Docker Compose installed, you can create a local development environment that includes not only the PipelineWise executables but also a pre-configured development project with some databases as source and targets for a more convenient development experience and to run integration and end-to-end tests.

For further instructions about setting up local development environment go to Test Project for Docker Development Environment.
