PostgreSQL + JSONB

PostgreSQL + JSONB is a robust, battle-tested database that combines relational SQL with flexible JSON document storage.

Key Features:

• JSONB Indexing — Index JSON fields with GIN indexes for fast queries on nested scraped data.
• SQL + Documents — Query structured and semi-structured data together in a single database.
• Containment Queries — Find documents matching complex nested patterns with the @> operator.
• Strong Consistency — ACID transactions ensure scraped data integrity across relational and JSON columns.
• Ecosystem Maturity — Leverage decades of PostgreSQL tooling, extensions, and community support.

Whether you're storing varied product data, mixing structured metadata with raw scraped content, or building flexible schemas, PostgreSQL + JSONB provides the best of both relational and document worlds.
