PostgreSQL + JSONB

PostgreSQL + JSONB is a relational SQL database option that stores structured tables and flexible JSON documents in the same system.

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.

Use PostgreSQL + JSONB when scraped data needs relational guarantees, SQL joins, and native JSON document support without introducing a separate document database.
