terrafox-datalake 0.1.7

Automated connector wrapper for streaming data securely from a private MinIO Data Lake

Terrafox Data Lake Connector

A simple, secure wrapper module to stream files out of your private data lake into remote notebook runtimes seamlessly.

terrafox-datalake

A lightweight, universal, stream-native connector wrapper designed to stream datasets securely from private MinIO and S3-compatible Data Lakes straight into Pandas dataframes.

By replacing traditional file-system directory mapping wrappers (s3fs/fsspec) with direct object streaming via boto3, this package completely eliminates network edge bottlenecks, Cloudflare proxy payload limits, and 403 Forbidden credential collisions caused by background directory scanning.

Key Features

• Stream-Native Engine: Reads multi-gigabyte datasets (e.g., 1.3 GiB+ CSVs) linearly using high-performance byte-stream network chunks, keeping your local or Google Colab memory consumption minimal.
• Bypasses Proxy Blocks: Sidesteps standard reverse-proxy constraints (like Cloudflare Tunnel 100 MiB Client Max Body Size upload blocks) during active read cycles.
• Fully Universal & Repurposable: Zero hardcoded endpoints. Works natively out-of-the-box with your configured defaults or targets any custom local/cloud data lake clusters dynamically.
• Zero Configuration Conflict: Completely abstracts complex botocore configuration arguments, address styling structures, and signature parameters out of your notebooks.

Installation

Terrafox Data Lake

A lightweight Python package for securely connecting to and streaming data from private MinIO-based data lake environments.

Installation

pip install terrafox-datalake

Quick Start

1. Connecting Natively via Interactive Prompt

If no background credentials are found, calling connect() will securely prompt you for your data lake credentials.

import terrafox_datalake as dl

# Initialize the data lake client context securely
dl.connect()

---

2. Silent Credentials Injection (Automated Workflows)

For automated scripts, CI/CD pipelines, headless environments, or to bypass the interactive login prompt in Google Colab, set your credentials as environment variables before initializing the connection.

import os
import terrafox_datalake as dl

# Pre-populate session credentials
os.environ["MINIO_USER"] = "admin"
os.environ["MINIO_PASSWORD"] = "your_secure_password"
os.environ["MINIO_ENDPOINT"] = "https://minio.terrafoxai.com"

# Initialize the connection
dl.connect()

---

3. Advanced Usage: Connecting to Different Infrastructures

Terrafox Data Lake is designed to be dynamic and reusable. Switch seamlessly between production environments, staging clusters, or local development instances.

import terrafox_datalake as dl

# Connect to an alternate cluster or local MinIO instance
dl.connect(endpoint="https://local-testing-cluster.local:9000")

# Read data from a different environment
df = dl.read_csv(
    bucket="test-bucket",
    key="metrics.csv"
)

---

Example: Reading Data from a Data Lake

import terrafox_datalake as dl

dl.connect()

df = dl.read_csv(
    bucket="bigdata",
    key="vehicles.csv"
)

print(df.head())
