Flat File

The Flat File integration is used to upload a single flat file (like csv, parquet, and feather) into the data lineage graph.

Python Library

Installation

Install Flat File Grai package with pip

pip install grai-source-flatfile

Connecting & Syncing

The integration comes equipped with the client library already but we will need a python terminal or Jupyter Notebook to execute a few commands to establish a connection and begin querying the server.

Spin up your favorite python terminal then:

import os
from grai_source_flatfile.base import update_server

For now we will use the default user credentials though you are free to create a new user / api keys from the server admin interface at http://localhost:8000/admin (opens in a new tab).

client = ClientV1("localhost", "8000", username="null@grai.io", password="super_secret")

Now we can update the server with data from any postgres source. In order to do so you will need to pass credentials and namespace into the update_server function. Namespace is used to uniquely identify the nodes and when used consistently will allow you to add to the node from any source.

update_server(client, [flat_file fields])
