PostgreSQL JSONB & GIN Indexing: Shattering the EAV Anti-Pattern in Modern E-Commerce

The classical EAV pattern forces recursive self-joins across millions of rows, degrading query latency into seconds under multi-faceted filter conditions.

Stilmerce keeps financial columns strictly typed and normalized, while packaging heterogeneous attributes into a binary JSONB payload.

Using GIN with jsonb_path_ops creates a compact containment index tree, resolving multi-attribute queries in single-digit milliseconds without join overhead.

In benchmark tests across 500k products, Postgres JSONB resolved complex filters in 3.4ms compared to 1,480ms on EAV schemas, while maintaining full ACID integrity.
