Problem Statement -Many data engineers and analysts need to move data from BigQuery to a local or on-premise PostgreSQL instance for cost-efficient analysis, development, or backup. Existing solutions are either: -- **Enterprise-Heavy**: Requiring complex orchestration (Airflow, DBT, Dataflow) and high operational overhead. -- **Cost-Prohibitive**: Paid SaaS tools charge exorbitant fees based on row volume. -- **CLI-Only**: Lacking an accessible interface for non-technical or semi-technical users. +- **Large-scale data extraction** (1M+ patent records) +- **Intelligent schema mapping** and data transformation +- **Chunked processing** for memory efficiency +- **Error handling** and data validation +- **Multiple execution modes** (simple, scaled, debug) +- **Comprehensive logging** and monitoring +- **Containerized deployment** with Docker/Podman -### 2. Target Audience -- **Data Analysts**: Needing quick subsets of cloud data for local exploration. -- **Developers**: Building apps locally using production-like datasets. -- **DevOps Engineers**: Seeking a lightweight, self-hostable ETL tool without massive infra requirements. +### Key Features +Extract millions of patent records from BigQuery +Handle complex nested data structures (arrays, JSON) +Intelligent date parsing and format conversion +Configurable batch processing and chunking +Multiple pipeline strategies (simple, scaled, debug) +PostgreSQL schema with optimized indexes +Full Podman containerization +Comprehensive error handling and logging +ML-ready data exports with feature engineering + +--- -### 3. Solution Overview -**BQ2PG** is a high-performance migration engine designed to be "Lite yet Powerful."
