Dataset Card:

Enterprise High-Frequency SKU Depletion & WAF Telemetry Feed: N11

This repository contains an open 1,000-row verified benchmark sample of the N11 SKU depletion feed, structured with pre-indexed SQLite and Snappy Parquet partitions for quantitative market intelligence research.

Executive Summary

Brittle scrapers and broken proxy pools significantly degrade data pipeline reliability for quantitative analysts. This dataset provides a blueprint for bypassing enterprise-grade WAF (Cloudflare Bot Management/Turnstile) challenges. By focusing on protocol-level extraction and TLS/JA4 signature parity, we achieve 99.9% pipeline availability, delivering clean, deduplicated market signals for SKU velocity and inventory depletion.

Enterprise Deliverables Matrix

This feed is structured for direct ingestion into quantitative stacks:

• Pre-indexed SQLite (.sqlite): Instant local querying with indices on sku_id, price_usd, and timestamp.
• Snappy Parquet: Optimized for direct ingestion into Snowflake, Google BigQuery, and AWS Athena.
• Offline DataGrid (.html): A self-contained, zero-dependency interactive viewer for non-technical stakeholders to audit data quality.
• CDC JSONL Stream: Change Data Capture format for rapid integration into Enterprise RAG pipelines and vector database indexing.

Dataset Schema

Column	Type	Nullable	Description
sku_id	STRING	No	Unique N11 product identifier.
timestamp	DATETIME	No	ISO-8601 UTC execution time.
price_usd	FLOAT	No	Normalized price including basket-level discounts.
stock_level	INTEGER	Yes	Estimated inventory depth or availability flag.
velocity_depletion_rate	FLOAT	Yes	Calculated delta of stock level over 24h period.
target_domain	STRING	No	Originating marketplace domain (n11.com).
detected_waf	STRING	No	Active WAF signature (e.g., Cloudflare-Turnstile).
tls_ja4_signature	STRING	No	Fingerprint used for protocol-level parity.
delivery_status	STRING	No	Pipeline verification status (Success/Retry).
