Performance Issue
A significant performance degradation has been detected in queries filtering on the numeric_value column of the clinic_activity_logs table.
Current Behavior
- Query execution time: 2.68 seconds
- Full table scan required for filtering on numeric_value
- Typical duration: 667.7 microseconds
- Current z-score: 11.75 (significant deviation)
Root Cause
The absence of an index on the numeric_value column forces the database to perform full table scans when filtering on this column.
Solution
Added an index on the numeric_value column to optimize query performance:
CREATE INDEX idx_clinic_activity_logs_numeric_value ON clinic_activity_logs(numeric_value);
Impact
- Reduces query execution time
- Eliminates full table scans
- Improves overall application performance
