Palantir Python SDK

This SDK is incubating and subject to change.

Setup

pip install palantir-sdk

conda config --add channels conda-forge  # add conda-forge channel if not already enabled
conda install palantir-sdk
mamba install palantir-sdk  # alternatively install with mamba

Configuration for hostname and an authentication token are provided by environment variables (PALANTIR_HOSTNAME, PALANTIR_TOKEN)

PALANTIR_HOSTNAME is the hostname of your instance e.g. example.palantirfoundry.com
PALANTIR_TOKEN is a token acquired from the Tokens section of Foundry Settings

Authentication tokens serve as a private password and allows a connection to Foundry data. Keep your token secret and do not share it with anyone else. Do not add a token to a source controlled or shared file.

Examples

Read a Foundry Dataset into a Pandas DataFrame

from palantir.datasets import dataset

dataset("/Path/to/dataset") \
    .read_pandas()

            id        word  length     double boolean

Write a Pandas DataFrame to a Foundry Dataset

import pandas as pd
from palantir.datasets import dataset

df = pd.DataFrame({
    "string": ["one", "two"],
    "integer": [1, 2]
})

ds = dataset(f"/Path/to/dataset", create=True)
ds.write_pandas(df)

List files in a Dataset

from palantir.datasets import dataset

files = dataset("/Path/to/dataset") \
    .list_files() # returns a generator over pages of files

list(files)

[
    File("ri.foundry.main.dataset.2ed83c69-e87e-425e-9a1c-03b77b5b0831", "file.txt")
]

Read the contents of a file from a dataset (by name)

from palantir.datasets import dataset

dataset("/Path/to/dataset") \
    .file("file.txt") \
    .read()

b'Hello!'

Read the contents of a file from a dataset (by exploration / listing)

from palantir.datasets import dataset

files = dataset("/Path/to/dataset").list_files()
next(files).read()

b'Hello!'

Dataset functions also accept Resource Identifiers (rids)

from palantir.datasets import dataset

dataset("ri.foundry.main.dataset.a0a94f00-754e-49ff-a4f6-4f5cc200d45d") \
    .read_pandas()

  string  integer
0    one        1
1    two        2
