⭐ Features

• 📈 High Performance: Vector search powered by Redis HNSW or Qdrant.
• 🛠️ Simple API: Endpoints for index creation, insertion, and querying.
• 🔌 Embedding-agnostic: Works with any embedding model (OpenAI, Llama 3, HuggingFace, etc.).
• 💻 Interactive Setup Wizard: aquiles-rag configs walks you through full configuration for Redis or Qdrant.
• ⚡ Sync & Async clients: AquilesRAG (requests) and AsyncAquilesRAG (httpx) with embedding_model metadata support.
• 🧩 Extensible: Designed to integrate into ML pipelines, microservices, or serverless deployments.

🛠 Tech Stack

• Python 3.9+
• FastAPI
• Redis or Qdrant as vector store
• NumPy
• Pydantic
• Jinja2
• Click (CLI)
• Requests (sync client)
• HTTPX (async client)

⚙️ Requirements

1. Redis (standalone or cluster) — or Qdrant (HTTP / gRPC).
2. Python 3.9+
3. pip

Optional: run Redis locally with Docker:

docker run -d --name redis-stack -p 6379:6379 redis/redis-stack-server:latest

🚀 Installation

Via PyPI (recommended)

pip install aquiles-rag

From Source (optional)

git clone https://github.com/Aquiles-ai/Aquiles-RAG.git
cd Aquiles-RAG

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

# optional development install
pip install -e .

🔧 Configuration & Connection Options

Configuration is persisted at:

~/.local/share/aquiles/aquiles_config.json

Setup Wizard (recommended)

The previous manual per-flag config flow was replaced by an interactive wizard. Run:

aquiles-rag configs

The wizard prompts for everything required for either Redis or Qdrant (host, ports, TLS/gRPC options, API keys, admin user). At the end it writes aquiles_config.json to the standard location.

Manual config (advanced / CI)

If you prefer automation, generate the same JSON schema the wizard writes and place it at ~/.local/share/aquiles/aquiles_config.json before starting the server (or use the deploy pattern described below).

Redis connection modes (examples)

Aquiles-RAG supports multiple Redis modes:

1. Local Cluster

RedisCluster(host=host, port=port, decode_responses=True)

2. Standalone Local

redis.Redis(host=host, port=port, decode_responses=True)

3. Remote with TLS/SSL

redis.Redis(host=host, port=port, username=username or None,
            password=password or None, ssl=True, decode_responses=True,
            ssl_certfile=ssl_certfile, ssl_keyfile=ssl_keyfile, ssl_ca_certs=ssl_ca_certs)

4. Remote without TLS/SSL

redis.Redis(host=host, port=port, username=username or None, password=password or None, decode_responses=True)

📖 Usage

CLI

• Interactive Setup Wizard (recommended):

aquiles-rag configs

• Serve the API:

aquiles-rag serve --host "0.0.0.0" --port 5500

• Deploy with bootstrap script (pattern: deploy_*.py with run() that calls gen_configs_file()):

# Redis example
aquiles-rag deploy --host "0.0.0.0" --port 5500 --workers 2 deploy_redis.py

# Qdrant example
aquiles-rag deploy --host "0.0.0.0" --port 5500 --workers 2 deploy_qdrant.py

The deploy command imports the given Python file, executes its run() to generate the config (writes aquiles_config.json), then starts the FastAPI server.

REST API — common examples

1. Create Index

curl -X POST http://localhost:5500/create/index \
  -H "X-API-Key: YOUR_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "indexname": "documents",
    "embeddings_dim": 768,
    "dtype": "FLOAT32",
    "delete_the_index_if_it_exists": false
  }'

2. Insert Chunk (ingest)

curl -X POST http://localhost:5500/rag/create \
  -H "X-API-Key: YOUR_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "index": "documents",
    "name_chunk": "doc1_part1",
    "dtype": "FLOAT32",
    "chunk_size": 1024,
    "raw_text": "Text of the chunk...",
    "embeddings": [0.12, 0.34, 0.56, ...]
  }'

3. Query Top-K

curl -X POST http://localhost:5500/rag/query-rag \
  -H "X-API-Key: YOUR_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "index": "documents",
    "embeddings": [0.78, 0.90, ...],
    "dtype": "FLOAT32",
    "top_k": 5,
    "cosine_distance_threshold": 0.6
  }'

Python Client

Sync client

from aquiles.client import AquilesRAG

client = AquilesRAG(host="http://127.0.0.1:5500", api_key="YOUR_API_KEY")

# Create an index (returns server text)
resp_text = client.create_index("documents", embeddings_dim=768, dtype="FLOAT32")

# Insert chunks using your embedding function
def get_embedding(text):
    return embedding_model.encode(text)

responses = client.send_rag(
    embedding_func=get_embedding,
    index="documents",
    name_chunk="doc1",
    raw_text=full_text,
    embedding_model="text-embedding-v1"  # optional metadata sent with each chunk
)

# Query the index (returns parsed JSON)
results = client.query("documents", query_embedding, top_k=5)
print(results)

Async client

import asyncio
from aquiles.client import AsyncAquilesRAG

client = AsyncAquilesRAG(host="http://127.0.0.1:5500", api_key="YOUR_API_KEY")

async def main():
    await client.create_index("documents_async")
    responses = await client.send_rag(
        embedding_func=async_embedding_func,   # supports sync or async callables
        index="documents_async",
        name_chunk="doc_async",
        raw_text=full_text
    )
    results = await client.query("documents_async", query_embedding)
    print(results)

asyncio.run(main())

Notes

• Both clients accept an optional embedding_model parameter forwarded as metadata — helpful when storing/querying embeddings produced by different models.
• send_rag chunks text using chunk_text_by_words() (default ~600 words / ≈1024 tokens) and uploads each chunk (concurrently in the async client).

UI Playground

Open the web UI (protected) at:

http://localhost:5500/ui

Use it to:

• Run the Setup Wizard link (if available) or inspect live configs
• Test /create/index, /rag/create, /rag/query-rag
• Access protected Swagger UI & ReDoc after logging in

🏗 Architecture

1. Clients (HTTP/HTTPS, Python SDK, or UI Playground) make asynchronous HTTP requests.
2. FastAPI Server — orchestration and business logic; validates requests and translates them to vector store operations.
3. Vector Store — either Redis (HASH + HNSW/COSINE search) or Qdrant (collections + vector search).

⚠️ Backend differences & notes

• Metrics / /status/ram: Redis offers INFO memory and memory_stats() — for Qdrant the same Redis-specific metrics are not available (the endpoint will return a short message explaining this).
• Dtype handling: Server validates dtype for Redis (converts embeddings to the requested NumPy dtype). Qdrant accepts float arrays directly — dtype is informational/compatibility metadata.
• gRPC: Qdrant can be used over HTTP or gRPC (prefer_grpc=true in the config). Ensure your environment allows gRPC outbound/inbound as needed.

🔎 Test Suite

See the test/ directory for automated tests:

• client tests for the Python SDK
• API tests for endpoint behavior
• test_deploy.py for deployment / bootstrap validation
