sayou-connector 0.5.0

Connector components for the Sayou Data Platform

sayou-connector

Overview

The Universal Data Ingestion Engine for Sayou Fabric.

sayou-connector provides a unified interface to fetch data from diverse sources—Files, Cloud Drives, Databases, and SaaS APIs—normalizing everything into a standard format called SayouPacket.

It decouples the logic of Navigation (Generator) from Retrieval (Fetcher), enabling complex recursive crawling, pagination, and API traversal strategies out of the box.

1. Architecture & Role

The Connector Pipeline manages the Feedback Loop between discovery and retrieval. It yields a stream of SayouPacket objects ready for the next stage (Refinery).

1.1. Core Features

• Generator/Fetcher Pattern: Separates "Where to go next" (Generator) from "How to get it" (Fetcher).
• Unified Packet: Whether the source is a Notion Page or a PostgreSQL Row, the output is always a uniform SayouPacket.
• Resilience: Built-in rate limiting, retries, and error handling for unstable network sources.

3. Installation

pip install sayou-connector

4. Usage

The ConnectorPipeline acts as the entry point. It automatically detects the source type or accepts a specific strategy.

Case A: Local & Web (Simple)

Fetching simple files or web pages.

from sayou.connector import ConnectorPipeline

packets = ConnectorPipeline.process(
    source="./my_docs",
    strategy="file"
)

web_packets = ConnectorPipeline.process(
    source="https://news.daum.net/tech",
    strategy="web"
)

for packet in web_packets:
    print(f"[Fetched] {packet.uri} ({len(packet.data)} bytes)")

Case B: SaaS Integration (GitHub / Notion)

Fetching structured data from external APIs.

from sayou.connector import ConnectorPipeline

repo_packets = ConnectorPipeline.process(
    source="https://github.com/sayouzone/sayou-fabric",
    strategy="github"
)

print(f"Collected {len(list(repo_packets))} files from repo.")

Case C: Database Ingestion

Fetching rows from a database table.

from sayou.connector import ConnectorPipeline

db_config = {
    "host": "localhost",
    "user": "admin",
    "password": "password",
    "db": "sales_db"
}

# Fetch rows from 'orders' table
db_packets = ConnectorPipeline.process(
    source="orders", 
    strategy="postgres",
    config=db_config
)

# Each packet contains a batch of rows
for packet in db_packets:
    print(f"Batch rows: {len(packet.data)}")

---

5. Configuration Keys

The config dictionary is crucial for authentication and connection settings.

• auth: API Keys (e.g., github_token, notion_token, google_creds).
• db: Database credentials (host, port, user, password).
• crawl: Web crawling settings (user_agent, depth_limit, domain_lock).
• filter: File extensions to include/exclude (e.g., include=[".py", ".md"]).
