What it shows

Traditional EAV guarantees relational typing but requires 5+ table joins.
JSONB consolidates polymorphic attributes into single-row key-value blobs.
Hybrid schemas keep core filters relational while dynamic specs live in JSONB.

The takeaway

Keep query-critical fields in structured columns and push volatile product variant specs into indexed JSONB.
