mistralai-search-toolkit-storage-gcs 0.0.9

Google Cloud Storage ObjectStorage plugin for mistralai-search-toolkit

Google Cloud Storage Plugin for Search Toolkit

Google Cloud Storage backend for mistralai-search-toolkit.

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

Installation

pip install mistralai-search-toolkit-storage-gcs

Or as an optional dependency of the core package:

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

Quick Start: Load Files from GCS in Ingestion Pipeline

1. Upload a File to GCS

import asyncio
from mistralai.search.toolkit.plugins.storage.gcs import GCSBlobStorage

async def upload_file():
    storage = GCSBlobStorage(
        bucket_name="your-bucket",
        project_id="your-project",
    )

    # 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 GCS 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.gcs import GCSBlobStorage
from mistralai.search.toolkit.plugins.vespa import VespaClientConfig
from vespa_app import app

async def ingest_from_gcs():
    # Create GCS storage factory
    def gcs_storage_factory():
        return GCSBlobStorage(
            bucket_name="your-bucket",
            project_id="your-project",
        )

    # Create FileLoader backed by GCS
    file_loader = FileLoader(storage_factory=gcs_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 GCS
    num_chunks = await pipeline.run(documents=[
        "documents/document1.pdf",
        "documents/document2.pdf",
    ])

    print(f"Indexed {num_chunks} chunks")

asyncio.run(ingest_from_gcs())

Configuration

Basic Setup

storage = GCSBlobStorage(
    bucket_name="your-bucket",
    project_id="your-project",
)

Using Service Account

from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_file(
    "/path/to/service-account-key.json"
)

storage = GCSBlobStorage(
    bucket_name="your-bucket",
    project_id="your-project",
    credentials=credentials,
)

Authentication

Environment Variables

Set credentials using environment variables:

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account-key.json"

Or authenticate with gcloud CLI:

gcloud auth application-default login

The plugin will automatically use credentials from:

• GOOGLE_APPLICATION_CREDENTIALS environment variable
• Application Default Credentials (if running in GCP)
