Alexander Ioffe: JSONB Paths or GIN or Columns?

New benchmarks reveal that using standard database columns in PostgreSQL 17 outperforms JSONB with GIN indexes for most order data queries. The exception is when checking for multiple specific keys within a JSONB field.
Key takeaways
- Normalized columns excel in PostgreSQL 17 for order data.
- JSONB with GIN is slower for most common queries.
- Multi-key containment is the sole advantage for JSONB.
- Choose column storage for performance gains.
Why it matters
For professionals managing data with AI tools, this suggests optimizing database design by favoring normalized columns over JSONB for common query types. This can lead to faster data retrieval and processing when working with structured information.
