Graham McIntire	d68f0f2e08	fix: Remove non-immutable NOW() function from index predicate ... PostgreSQL requires functions in index predicates to be immutable. The NOW() function is not immutable, so we simplify the index to just order by received_at DESC without the WHERE clause. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-07-30 14:15:13 -05:00
Graham McIntire	11dbf8215c	feat: Implement comprehensive performance optimizations ... - Add database indexes for common query patterns (path, callsign, device, weather) - Implement packet batching in LiveView to reduce client updates - Create PreparedQueries module for frequently executed database queries - Add KNN (K-nearest neighbors) spatial queries using PostGIS - Implement configurable debouncing for map bounds and hover events - Integrate with existing Redis cache for device lookups - Optimize cleanup worker with batch processing (already implemented) These optimizations significantly improve query performance and reduce database load, especially for high-traffic scenarios. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-07-30 14:14:00 -05:00
