Database Optimization
Indexing Strategy
-- Geographic indexes for location queries
CREATE INDEX idx_park_location_coordinates ON parks_parklocation USING GIST (coordinates);
CREATE INDEX idx_ride_location_coordinates ON rides_ridelocation USING GIST (coordinates);
-- Text search indexes
CREATE INDEX idx_park_name_search ON parks_park USING GIN (to_tsvector('english', name));
CREATE INDEX idx_ride_name_search ON rides_ride USING GIN (to_tsvector('english', name));
-- Foreign key indexes for joins
CREATE INDEX idx_ride_park_id ON rides_ride (park_id);
CREATE INDEX idx_ride_manufacturer_id ON rides_ride (manufacturer_id);
CREATE INDEX idx_review_user_id ON reviews_review (user_id);
-- Composite indexes for common queries
CREATE INDEX idx_ride_category_status ON rides_ride (category, status);
CREATE INDEX idx_park_country_state ON parks_parklocation (country, state);
Query Optimization
- Select Related: Minimize database queries with
select_related()for foreign keys - Prefetch Related: Optimize many-to-many and reverse foreign key queries
- Database Functions: Use PostgreSQL-specific functions for complex queries
- Connection Pooling: Efficient database connection management

Appendix F: Troubleshooting Guide
Common Issues and Solutions
Database Connection Issues
# Check database connectivity
pg_isready -h localhost -p 5432 -U thrillwiki
# Reset database connections
uv run manage.py dbshell
SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE datname = 'thrillwiki';
# Check for long-running queries
SELECT pid, now() - pg_stat_activity.query_start AS duration, query
FROM pg_stat_activity
WHERE (now() - pg_stat_activity.query_start) > interval '5 minutes';
Cache Issues
# Check Redis connectivity
redis-cli ping
# Clear all cache
redis-cli FLUSHALL
# Monitor cache usage
redis-cli INFO memory
# Check specific cache keys
redis-cli KEYS "thrillwiki:*"
Celery Task Issues
# Check Celery worker status
celery -A config inspect active
# Purge all tasks
celery -A config purge
# Monitor task queue
celery -A config inspect reserved
# Check failed tasks
celery -A config events
Performance Issues
# Enable Django debug toolbar
INSTALLED_APPS += ['debug_toolbar']
MIDDLEWARE += ['debug_toolbar.middleware.DebugToolbarMiddleware']
# Profile database queries
from django.db import connection
print(f"Queries executed: {len(connection.queries)}")
for query in connection.queries:
print(f"Time: {query['time']}s - SQL: {query['sql'][:100]}...")
# Monitor memory usage
