mistralai-search-toolkit-storage-azure 0.0.9

Azure Blob ObjectStorage plugin for mistralai-search-toolkit

Azure Blob Storage Plugin for Search Toolkit

Azure Blob Storage backend for mistralai-search-toolkit.

This plugin implements the Search Toolkit's ObjectStorage interface, enabling the ingestion pipeline to load files directly from Azure Blob Storage.

Installation

pip install mistralai-search-toolkit-storage-azure

Or as an optional dependency of the core package:

pip install mistralai-search-toolkit[storage-azure]

Quick Start: Load Files from Azure in Ingestion Pipeline

1. Upload a File to Azure Blob Storage

import asyncio
from mistralai.search.toolkit.plugins.storage.azure import AzureBlobStorage

async def upload_file():
    storage = AzureBlobStorage(
        container_name="documents",
        account_name="your-account",
    )

    # Upload a file
    with open("document.pdf", "rb") as f:
        data = f.read()

    await storage.put(key="documents/document.pdf", data=data)

asyncio.run(upload_file())

2. Load Files from Azure in Ingestion Pipeline

import asyncio
import os
from mistralai.search.toolkit.ingestion.loaders import FileLoader
from mistralai.search.toolkit.ingestion.pipelines import Pipeline
from mistralai.search.toolkit.ingestion.text_splitters import CharacterTextSplitter
from mistralai.search.toolkit.embedders import MistralEmbedder, MODEL_1024_EMBEDDING
from mistralai.client import Mistral
from mistralai.search.toolkit.plugins.storage.azure import AzureBlobStorage
from mistralai.search.toolkit.plugins.vespa import VespaClientConfig
from vespa_app import app

async def ingest_from_azure():
    # Create Azure storage factory
    def azure_storage_factory():
        return AzureBlobStorage(
            container_name="documents",
            account_name="your-account",
        )

    # Create FileLoader backed by Azure
    file_loader = FileLoader(storage_factory=azure_storage_factory)

    # Create ingestion pipeline
    mistral_client = Mistral(api_key=os.environ.get("MISTRAL_API_KEY"))
    vespa_config = VespaClientConfig(
        endpoint=os.environ.get("VESPA_ENDPOINT", "http://localhost:8080"),
    )
    vector_store = app.get_search_index(vespa_config, collection_name="articles")

    pipeline = Pipeline(
        loader=file_loader,
        text_splitter=CharacterTextSplitter(chunk_size=512),
        embedder=MistralEmbedder(client=mistral_client, model_name=MODEL_1024_EMBEDDING),
        stores=vector_store,
    )

    # Ingest documents from Azure
    num_chunks = await pipeline.run(documents=[
        "documents/document1.pdf",
        "documents/document2.pdf",
    ])

    print(f"Indexed {num_chunks} chunks")

asyncio.run(ingest_from_azure())

Configuration

Basic Setup

storage = AzureBlobStorage(
    container_name="documents",
    account_name="your-account",
)

Using Connection String

storage = AzureBlobStorage(
    container_name="documents",
    connection_string="DefaultEndpointsProtocol=https;AccountName=...;AccountKey=...",
)

Using Account Key

storage = AzureBlobStorage(
    container_name="documents",
    account_name="your-account",
    account_key="your-key",
)

Using Managed Identity

from azure.identity.aio import DefaultAzureCredential

storage = AzureBlobStorage(
    container_name="documents",
    account_name="your-account",
    credential=DefaultAzureCredential(),
)

Local Development

For local testing, use Azurite:

docker run -p 10000:10000 mcr.microsoft.com/azure-storage/azurite azurite-blob --blobHost 0.0.0.0

Configure to use local emulator:

storage = AzureBlobStorage(
    container_name="documents",
    connection_string="DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=<key>;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1/;",
)
