ParadeDB Search Performance Improvements
TL;DR
PlanetScale launched TIN, a full-text search extension for Postgres, achieving performance that is at least 8x faster than ParadeDB's text search. This prompted ParadeDB to enhance their own search capabilities.
✦ Why It Matters
Evaluate your current text search implementation and consider adopting similar optimization strategies.
Key Takeaways
- Optimize data structures for better locality to reduce access times.
- Implement MAXSCORE for efficient disjunction query processing.
- Ensure fair benchmarking by standardizing query syntax.
- Consider the trade-offs between document identifier types in search engines.
How It Works
ParadeDB improved its text search performance by reorganizing fieldnorm storage to be sequentially accessed alongside postings, significantly reducing random page accesses during scoring.
