- Reduce cache size from 8GB to 512MB (still plenty for 2.4GB DB)
- Reduce mmap_size from 10GB to 256MB (reasonable default)
- Use default page size (4KB) instead of 8KB
- Use default WAL checkpoint interval (1000 pages)
- Remove redundant pragmas (threads, cache_spill, read_uncommitted)
- Clean up connection string to only use _txlock parameter
- Keep synchronous=OFF for performance (since we have mutex protection)
- Add internal mutex to Database struct with lock/unlock wrappers
- Add debug logging for lock acquisition and release with timing
- Wrap all write operations with database mutex
- Use _txlock=immediate in SQLite connection string
This works around apparent issues with SQLite's internal locking
not properly respecting busy_timeout in production environment.
- Add _txlock=immediate to SQLite connection string
- This prevents deadlocks by acquiring write locks at transaction start
- Multiple concurrent writers now queue properly instead of failing instantly
- Resolves 'database table is locked' errors in production
- Fix Ctrl-C shutdown by using fx.Shutdowner instead of just canceling context
- Pass context from fx lifecycle to rw.Run() for proper cancellation
- Adjust WAL settings: checkpoint at 50MB, max size 100MB
- Reduce busy timeout from 30s to 2s to fail fast on lock contention
This should fix the issue where Ctrl-C doesn't cause shutdown and improve
database responsiveness under heavy load.
- Add VACUUM on startup to defragment database
- Increase cache size from 256MB to 2GB for better performance
- Increase mmap_size from 256MB to 512MB
- Add PRAGMA analysis_limit=0 to disable automatic ANALYZE
- Remove PRAGMA optimize which could trigger slow ANALYZE
These changes should dramatically improve query performance and prevent
the 5+ second query times seen in production.
- Add debug logging for goroutines and memory usage (enabled via DEBUG=routewatch)
- Increase SQLite connection pool from 1 to 10 connections for better concurrency
- Optimize SQLite pragmas for balanced performance and safety
- Add proper shutdown handling for peering handler
- Define constants to avoid magic numbers in code

- Keep all performance optimizations and pragmas
The CGO driver may provide better performance for write-heavy
workloads compared to the pure Go implementation.
Queries in the 50-70ms range are acceptable for now given SQLite's
write serialization constraints. Setting threshold to 100ms to focus
on truly problematic queries.
