SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides structured guidance for architectural decisions across PostgreSQL, DuckDB, Parquet, and PGVector, helping teams design scalable, maintainable data platforms.

Core Features & Use Cases

  • Cross-database design patterns for OLTP, OLAP, and vector search workloads.
  • Hybrid storage and maintenance tuning recommendations, covering schema, indexing, partitioning, and data layout.
  • Use case: plan a multi-database stack that supports transactional workloads in PostgreSQL, analytic workloads in DuckDB, storage in Parquet, and vector search in PGVector.

Quick Start

Ask for a cross-database architecture proposal for a new application using PostgreSQL for metadata, DuckDB for analytics, Parquet for storage, and PGVector for embeddings.

FAQPage Schema
How do I design a multi-database architecture using PostgreSQL, DuckDB, and Parquet?▼

A multi-database architecture uses PostgreSQL for OLTP metadata, DuckDB for OLAP analytics, Parquet for columnar storage, and PGVector for similarity search, ensuring maintainable cross-database conventions.

When do I need PGVector for vector search in a PostgreSQL database?▼

You need PGVector when your PostgreSQL database requires similarity search capabilities, enabling storage and querying of vector embeddings directly within transactional workloads.

What's the best way to configure DuckDB for analytic workloads alongside PostgreSQL?▼

Configuring DuckDB for analytics involves using Parquet for storage, applying maintenance tuning, and establishing cross-database patterns to separate OLAP processing from PostgreSQL OLTP operations.

Does this approach support schema design and indexing for both OLTP and OLAP scenarios?▼

Yes, this approach supports schema design and indexing across OLTP and OLAP by providing hybrid storage tuning, partitioning guidance, and indexing strategies for multi-database ecosystems.

How do I plan a data platform stack with Parquet storage and vector search?▼

Planning a data platform with Parquet and vector search requires mapping storage to Parquet, transactions to PostgreSQL, analytics to DuckDB, and similarity search to PGVector using best-practice deployment patterns.
