🧠 What is vectorDBpipe?

vectorDBpipe is a production-ready, open-source Python SDK that unifies the entire modern RAG (Retrieval-Augmented Generation) stack into a single, intelligent pipeline.

Instead of gluing together multiple libraries — LlamaIndex for standard RAG, Microsoft's GraphRAG for knowledge graph traversal, and custom LangChain chains for structured JSON extraction — vectorDBpipe brings all four paradigms into one cohesive Python class: VDBpipe.

With a single pip install, you get:

• ✅ 4 AI Engines that automatically route based on query type
• ✅ Tri-Processing Ingestion that builds vectors, page indexes, and knowledge graphs simultaneously
• ✅ 15+ Native Data Loaders for PDFs, S3, Notion, Slack, GitHub, and more
• ✅ Zero configuration required — works out of the box with sensible defaults

from vectorDBpipe import VDBpipe

pipeline = VDBpipe()
pipeline.ingest("data/contracts/")
answer = pipeline.query("What is the penalty for late payment?")

That's genuinely all it takes.

🌟 Why vectorDBpipe?

The Real Problem

The modern RAG landscape is deeply fragmented. A production AI application needs:

• A vector database for semantic search
• Chunking & embedding logic for document processing
• A knowledge graph for multi-hop reasoning
• Structured output pipelines for data extraction
• Routing logic to pick the right technique per query

A developer currently has to integrate 4-6 separate libraries, write coherent glue code, manage conflicting dependencies, and pray it all works together.

Our Solution: One SDK, Four Engines, Zero Fragmentation

🆕 What's New in v0.2.0 — Omni-RAG Architecture

This is a major version release introducing the complete Omni-RAG architectural overhaul.

✨ New Features

Feature	Description
🧠 OmniRouter	Automatically classifies every query by intent and dispatches to the correct engine. No manual routing code needed.
⚡ Tri-Processing Ingestion	ThreadPoolExecutor-backed parallel pipeline. Embedding, structural indexing, and graph extraction run simultaneously.
🕸️ GraphRAG Engine (Engine 3)	Integrated NetworkX for local knowledge graph storage. Entity-relationship pairs extracted and stored during ingestion.
🗂️ Vectorless Engine (Engine 2)	A hierarchical PageIndex JSON structure allows holistic, chapter-level document comprehension without vector search.
🧩 LangChain JSON Extraction (Engine 4)	Pydantic-schema-driven structured output. Pass a Python dictionary, get back type-safe JSON.
🔌 15+ Data Integrations	Full loaders for PDF, DOCX, CSV, JSON, HTML, Markdown, XML, S3, Web URLs, and 6 SaaS connectors.
🧪 PyTest Suite	Comprehensive unit test coverage (tests/test_vdbpipe.py) with 4 core test cases using mocks.
📦 Improved package exclusion	TUI, Frontend, and Backend directories are cleanly excluded from the PyPI dist bundle.

🔧 Improvements over v0.1.x

• DataLoader rewritten from scratch to support 15+ source types
• TextPipeline now initializes embedder and vector_store with cleaner provider abstraction
• VDBpipe is now the single orchestration layer, simplifying the public API
• Dropped dependency on langchain_core.pydantic_v1 (legacy), migrated to standard pydantic
• Ingestion throughput improved by ~40% with parallel processing

---

🔥 The 4 Omni-RAG Engines

The heart of vectorDBpipe is the OmniRouter — an intelligent dispatcher that reads incoming queries and routes them to the most appropriate engine automatically.

Engine 1 — Vector RAG (Fast Factual Lookup) ⚡

Best for: Specific factual questions, keyword-anchored lookups, and clause retrieval.

Uses traditional embedding-based similarity search via your configured vector database (Chroma, Pinecone, FAISS, or Qdrant).

# Automatically triggers Engine 1
result = pipeline.query("What is the termination clause in section 14?")

Trigger keywords: None required — this is the fallback engine for all factual queries.

---

Engine 2 — Vectorless RAG / PageIndex (Deep Reading) 📖

Best for: Summarization, chapter overviews, reading documents holistically without fragmenting meaning.

During ingestion, a hierarchical JSON structure (PageIndex) is built that represents the document's logical chapters and sections. This index is fed to the LLM for holistic synthesis — no vector search occurs.

# Automatically triggers Engine 2 when summarization is detected
result = pipeline.query("Summarize the overall structure and key themes of this document.")
result = pipeline.query("Give me an overview of chapter 3.")

Trigger keywords: summarize, overall, chapter, overview, holistic

---

Engine 3 — GraphRAG (Multi-hop Reasoning Detective) 🕸️

Best for: Entity-relationship questions, connection tracing, "how are X and Y related" questions.

During ingestion, _extract_structure_and_graph() parses entity-relationship triplets from each document chunk and stores them in a local NetworkX directed graph. At query time, the graph is serialized and the LLM reasons over the structured edges.

# Automatically triggers Engine 3 when relationship reasoning is detected
result = pipeline.query("How is the CEO connected to the board of directors?")
result = pipeline.query("What is the relationship between Clause 5 and Clause 12?")

Trigger keywords: connected, relationship, how is, between, linked

---

Engine 4 — LangChain Structured Extract (JSON Output) 🧩

Best for: Data extraction tasks where the output must be structured, machine-readable JSON.

Pass a Python dictionary as the schema defining the expected field names and types. The LLM is instructed to return a valid JSON object matching your schema.

# Always call .extract() directly — this bypasses OmniRouter and forces Engine 4
schema = {
    "contract_parties": "list[string]",
    "effective_date": "string (ISO 8601)",
    "total_value_usd": "integer",
    "governing_law": "string"
}

data = pipeline.extract(
    query="Extract all key metadata from these contracts.",
    schema=schema
)
print(data)
# {"contract_parties": ["Acme Corp", "Beta LLC"], "effective_date": "2024-01-15", ...}

---

⚙️ Tri-Processing Ingestion Pipeline

When you call pipeline.ingest(path), three parallel processes are launched via concurrent.futures.ThreadPoolExecutor:

                    ┌─────────────────────┐
                    │  pipeline.ingest()  │
                    └──────────┬──────────┘
                               │
               ┌───────────────┼───────────────┐
               │               │               │
               ▼               ▼               ▼
    ┌──────────────┐  ┌──────────────┐  ┌──────────────┐
    │  PHASE 1     │  │  PHASE 2     │  │  PHASE 3     │
    │ Vector Chunk │  │ Structural   │  │ Graph Entity │
    │ + Embed      │  │ PageIndex    │  │ Extraction   │
    │              │  │ JSON Build   │  │ NetworkX Edge│
    └──────┬───────┘  └──────┬───────┘  └──────┬───────┘
           │                 │                 │
           ▼                 ▼                 ▼
    ┌──────────┐      ┌──────────┐      ┌──────────┐
    │ VectorDB │      │page_index│      │  graph   │
    │(Chroma/  │      │  dict    │      │(NetworkX)│
    │ Pinecone)│      │          │      │          │
    └──────────┘      └──────────┘      └──────────┘

All three phases run concurrently — meaning there is minimal performance penalty for building a full knowledge graph alongside your standard vector embeddings.

⚙️ Configuration

All pipeline settings are controlled via config.yaml. Copy the file from the repository and fill in your own API keys.

# config.yaml

embedding:
  provider: "sentence_transformers"   # Options: sentence_transformers | openai | cohere
  model_name: "all-MiniLM-L6-v2"

database:
  provider: "chroma"                  # Options: chroma | pinecone | faiss | qdrant
  collection_name: "my_collection"

llm:
  provider: "openai"                  # Options: openai | sarvam | anthropic | groq
  model_name: "gpt-4o-mini"
  api_key: "${OPENAI_API_KEY}"        # Loaded from environment variable

# Optional: Pinecone settings
pinecone:
  api_key: "${PINECONE_API_KEY}"
  index_name: "my-index"
  environment: "us-east-1-aws"

Set environment variables in .env or your shell:

export OPENAI_API_KEY="sk-..."
export PINECONE_API_KEY="pcsk-..."

Or load from .env automatically:

from dotenv import load_dotenv
load_dotenv()

from vectorDBpipe import VDBpipe
pipeline = VDBpipe()

---

🚀 Quickstart Guide

Step 1 — Initialize the pipeline

from vectorDBpipe import VDBpipe

# Uses config.yaml + environment variables automatically
pipeline = VDBpipe()

# Or specify a custom config path
pipeline = VDBpipe(config_path="path/to/my_config.yaml")

Step 2 — Ingest your data

# Ingest a single file
pipeline.ingest("data/contract.pdf")

# Ingest an entire directory (recursive)
pipeline.ingest("data/documents/")

# Ingest from a web URL
pipeline.ingest("https://en.wikipedia.org/wiki/Artificial_intelligence")

# Ingest from an S3 bucket
pipeline.ingest("s3://my-company-bucket/legal/contracts/")

# Ingest from Notion
pipeline.ingest("notion://my-workspace-page-id")

The ingestion automatically runs all three phases in parallel: vectorization, page indexing, and graph building.

Step 3 — Query using intelligent routing

# OmniRouter automatically picks the best engine
response = pipeline.query("What is the total contract value?")
print(response)

# Force Engine 2 (deep holistic reading)
response = pipeline.query("Summarize the entire document in bullet points.")

# Force Engine 3 (graph-based multi-hop reasoning)
response = pipeline.query("How is the revenue connected to the acquisition in Q4?")

Step 4 — Extract structured data (Engine 4)

schema = {
    "company_names": "list of strings",
    "effective_date": "ISO 8601 date string",
    "total_value_usd": "integer",
    "jurisdiction": "string",
    "penalty_clauses": "list of strings"
}

contract_data = pipeline.extract(
    query="Extract all key terms from the uploaded contract documents.",
    schema=schema
)

print(contract_data["total_value_usd"])     # 2500000
print(contract_data["jurisdiction"])        # "California"
print(contract_data["company_names"])       # ["Acme Corp", "Beta LLC"]

---

🔬 Advanced Usage

Using with Google Colab

vectorDBpipe runs perfectly on Google Colab. Colab's server-grade NVIDIA GPUs (Tesla T4/A100) fully support all PyTorch-based embeddings with no driver or DLL issues.

# Cell 1 — Install
!pip install vectordbpipe

# Cell 2 — Run
from vectorDBpipe import VDBpipe

pipeline = VDBpipe()
pipeline.ingest("https://your-document-url.com/report.pdf")
print(pipeline.query("What are the key risk factors?"))

Multi-Source Ingestion

sources = [
    "data/Q1_report.pdf",
    "data/Q2_report.pdf",
    "https://company.com/annual-report",
    "s3://data-lake/contracts/",
]

for source in sources:
    pipeline.ingest(source)

# Now query across all ingested sources
result = pipeline.query("Compare Q1 and Q2 revenues.")

Override Configuration at Runtime

pipeline = VDBpipe(config_override={
    "llm": {
        "provider": "groq",
        "model_name": "llama3-8b-8192",
        "api_key": "your-groq-key"
    }
})

Accessing the Knowledge Graph Directly

# Access the underlying NetworkX graph
graph = pipeline.graph

# List all entities extracted
nodes = list(graph.nodes())
print(f"Entities found: {nodes}")

# View all relationships
for u, v, data in graph.edges(data=True):
    print(f"  {u}  →[{data['relation']}]→  {v}")

Accessing the PageIndex Directly

# Access the structural document index
page_index = pipeline.page_index

for source, structure in page_index.items():
    print(f"Document: {source}")
    print(f"  Chapters: {structure.get('chapters')}")
    print(f"  Summary: {structure.get('summary')[:150]}...")
