A Guide to Comprehensive Indexing Optimization
Xata Agent provides a complete index optimization solution:
- Missing Index Detection: Analyze query plans to identify full table scan operations that do not use indexes and recommend the most appropriate index type
- Redundant Index Cleanup: Identify rarely used or functionally duplicated indexes (e.g., single-column indexes overwritten by multi-column indexes)
- Index rebuilding recommendations: index that suggests the need for REINDEX based on the bloat rate (over 30%)
- Specialty Optimization: recommend GIN indexes for JSONB fields, BRIN indexes for range queries, and other specialized recommendations
Hands-on steps:
1. Go to the "Slow queries" page to view the top 10 inefficient queries.
2. Click on "Analysis" for a detailed interpretation of the implementation plan.
3. Use "EXPLAIN ANALYZE" to verify effectiveness before adopting recommendations
4. Changes to large table indexes are recommended to be made during low peak periods
