altastata 0.1.29

A Python package for Altastata data processing and machine learning integration

Altastata Python Package

A powerful Python package for secure, encrypted cloud storage with seamless integration for data processing, AI, machine learning, and RAG applications.

Installation

pip install altastata

Features

• fsspec filesystem interface - Use standard Python file operations with encrypted cloud storage
• Real-time Event Notifications - Listen for file share, delete, and create events
• LangChain Integration - Native support for document loaders and vector stores
• PyTorch & TensorFlow Support - Custom datasets for machine learning workflows
• Multi-cloud Support - Works with AWS, Azure, GCP, and more
• End-to-end Encryption - AES-256 encryption with zero-trust architecture

# Create an instance of AltaStataFunctions
altastata_functions = AltaStataFunctions.from_credentials(user_properties, private_key)
altastata_functions.set_password("my_password")

PyTorch & TensorFlow Integration

# Register the altastata functions for PyTorch or TensorFlow as a custom dataset
register_altastata_functions_for_pytorch(altastata_functions, "my_account")
register_altastata_functions_for_tensorflow(altastata_functions, "my_account")

# For PyTorch application use
torch_dataset = AltaStataPyTorchDataset(
    "my_account",
    root_dir=root_dir,
    file_pattern=pattern,
    transform=transform
)

# For TensorFlow application use
tensorflow_dataset = AltaStataTensorFlowDataset(
    "my_account",
    root_dir=root_dir,
    file_pattern=pattern,
    preprocess_fn=preprocess_fn
)

fsspec Integration

Altastata implements the fsspec interface, making it compatible with any Python library that uses standard file operations:

from altastata import AltaStataFunctions
from altastata.fsspec import create_filesystem

# Create AltaStata connection
altastata_functions = AltaStataFunctions.from_account_dir('/path/to/account')
altastata_functions.set_password("your_password")

# Create fsspec filesystem
fs = create_filesystem(altastata_functions, "my_account")

# Use it like any Python file system
files = fs.ls("Public/")
with fs.open("Public/Documents/file.txt", "r") as f:
    content = f.read()
    print(content)

This means you can use Altastata with pandas, dask, xarray, and hundreds of other libraries without any special configuration.

Event Listener

Get real-time notifications when file operations occur:

from altastata import AltaStataFunctions

# Event handler
def event_handler(event_name, data):
    print(f"📢 Event: {event_name}, Data: {data}")
    if event_name == "SHARE":
        print("File was shared!")
    elif event_name == "DELETE":
        print("File was deleted!")

# Initialize with callback server
altastata = AltaStataFunctions.from_account_dir(
    '/path/to/account',
    enable_callback_server=True,
    callback_server_port=25334
)
altastata.set_password("your_password")

# Register listener
listener = altastata.add_event_listener(event_handler)

# Events will now be delivered in real-time!
# See examples/event-listener-example/ for complete demos

Perfect for:

• Data sharing among the users
• Audit logging and compliance
• Workflow automation

See examples/event-listener-example/ for complete documentation and working examples.

LangChain Integration

Use Altastata as a document source for LangChain applications:

from langchain.document_loaders import DirectoryLoader
from altastata.fsspec import create_filesystem
from altastata import AltaStataFunctions

# Create AltaStata connection
altastata_functions = AltaStataFunctions.from_account_dir('/path/to/account')
altastata_functions.set_password("your_password")

# Create fsspec filesystem
fs = create_filesystem(altastata_functions, "my_account")

# Use with LangChain document loaders
loader = DirectoryLoader("Public/Documents/", filesystem=fs)
documents = loader.load()

# Use with vector stores
from langchain.vectorstores import FAISS
from langchain.embeddings import OpenAIEmbeddings

vectorstore = FAISS.from_documents(documents, OpenAIEmbeddings())

Perfect for:

• RAG (Retrieval-Augmented Generation) applications
• Document processing pipelines
• Knowledge base construction
• Multi-modal AI applications
