Key findings: GIN indexes do not accelerate ->> extraction queries (the most common misconception), B-tree expression indexes are ~6x smaller than GIN and 3,500x faster for targeted key lookups, and jsonb_path_ops produces indexes ~37% smaller than default GIN for containment-only workloads. Includes a decision framework for choosing the right strategy, common mistakes like missing type casts on expression indexes, and guidance on when to promote JSONB fields to typed columns. ## Full article daily.dev links to this article rather than hosting it.
