Foundry DevTools

Seamlessly run your Palantir Foundry Repository transforms code and more on your local machine. Foundry DevTools is a set of useful libraries to interact with the Foundry APIs. There are currently three high level entrypoints to Foundry DevTools:

• FoundryRestClient

  • An API client that contains an opinionated client implementation to some of Foundry's APIs.

  • For example:

    from foundry_dev_tools import FoundryRestClient
    
    # Queries the Foundry SQL Server with spark SQL dialect
    rest_client = FoundryRestClient()
    df = rest_client.query_foundry_sql("SELECT * FROM `/path/to/test_dataset`", branch='master')
    df.to_string()
    

• FoundryFileSystem

  • An implementation of fsspec for Foundry. Useful to interact with Foundry from popular data science libraries such as pandas or dask.

  • For example:

  import fsspec
  dataset_rid = 'ri.foundry.main.dataset.4c33cd4-6fe3-7a13-5aab-703c1b80c9f8'
  with fsspec.open(f"foundry://{dataset_rid}/test.txt", "r") as f:
      print(f.read())
  'content of test.txt'
  

• A transforms implementation

  • An implementation of the Foundry transforms package that internally uses the CachedFoundryClient. This allows you to seamlessly run your Palantir Foundry Code Repository transforms code on your local machine. Foundry DevTools does not cover all of Foundry's features, more on this here.

Quickstart

pip install foundry-dev-tools

Further instructions can be found in our documentation.

Why did we build this?

• Local development experience in your favourite IDE (PyCharm, VSCode, ...)
  • Access to modern developer tools and workflows such as pylint, black, isort, pre-commit hooks etc.
• Quicker turnaround time when making changes
  • Debug, change code and run in a matter of seconds instead of minutes
• No accidental or auto commits
  • Keep your git history clean
