Performance Optimization: Fix N+1 Query in ClinicActivityController-created-by-agentic

[shaykeren]

Current Issue

Performance issue detected in the ClinicActivityController.getLogs endpoint:

• N+1 query pattern causing 82 repeated queries
• Query execution time: 2.68s vs expected 667.7μs
• Affects 28% of requests to /api/clinic-activity/query-logs
• Trace ID: 39D9E615CA256B729B4A4865392064D7

Solution Implemented

A pull request (#100) has been created that implements the following changes:

1. Implemented batch processing for queries
2. Added BATCH_SIZE configuration (1000 records per batch)
3. Added proper error handling and logging
4. Implemented OpenTelemetry tracing for performance monitoring
5. Added query limit to prevent excessive data fetching

Performance Impact

• Reduces number of database queries from 82 to 1 per request
• Expected query execution time improvement from 2.68s to ~667.7μs
• Reduces database connection overhead
• Improves overall endpoint response time

Additional Notes

• The solution includes proper OpenTelemetry instrumentation for monitoring
• Error handling has been improved with proper logging
• The batch size can be adjusted based on performance requirements
