Each handler queue held 100,000 message pointers; a message is retained
until the slowest handler drains it, so all four full was a derived worst
case near 800 MiB. Twenty thousand is about four seconds of feed at peak
and caps that at roughly 160 MiB. The streamer already drops rather than
blocks on a full queue, so the smaller bound is safe.
Batch sizes are unchanged. The largest, asnBatchSize, is 30,000 and now
exceeds its queue, but each queued message contributes every ASN in its
path, and every handler also flushes on its own timer regardless of fill,
so batches still flush and no size change is warranted.
Model: opus-4-8
- Add GC statistics (run count, total/last pause, heap usage)
- Add BGP peer count tracking from RIS Live OPEN/NOTIFICATION messages
- Add route churn rate metric (announcements + withdrawals per second)
- Add announcement and withdrawal counters
- Add footer with attribution, license, and git revision
- Embed git revision at build time via ldflags
- Update HTML template to display all new metrics
- Remove UUID primary keys from ASNs table, use ASN number as primary key
- Update announcements table to reference ASN numbers directly
- Rename asns.number column to asns.asn for consistency
- Add prefix tracking to PrefixHandler to populate prefixes_v4/v6 tables
- Add UpdatePrefixesBatch method for efficient batch updates
- Update all database methods and models to use new schema
- Fix all references in code to use ASN field instead of Number
- Update test mocks to match new interfaces
- Create live_routes_v4 and live_routes_v6 tables
- Update all database methods to use appropriate table
- Add IP version detection in database queries
- Remove filtering by ip_version column for better performance
- Fix route count queries that were timing out
- Update PrefixHandler to include IP version in deletions
- Increase PrefixHandler batch size from 20k to 25k (25% increase)
- Add missing index on origin_asn for live_routes table
- This index significantly speeds up AS detail page queries
- Add code to create missing indexes on existing databases
- Increase prefix batch size from 5K to 20K
- Increase ASN batch size from 10K to 30K
- Add comments warning not to reduce batch timeouts
- Add comments warning not to increase queue sizes above 100K
- Maintains existing batch timeouts for efficiency
- Add v4_ip_start and v4_ip_end columns to live_routes table
- Calculate IPv4 CIDR ranges as 32-bit integers for fast lookups
- Update PrefixHandler to populate IPv4 range fields
- Add GetASInfoForIP method with optimized IPv4 queries
- Add comprehensive tests for IP conversion functions
- Increase PrefixHandler queue size to 500k and batch size to 25k
- Set SQLite PRAGMA synchronous=OFF for faster writes (trades durability)
- Increase SQLite cache to 1GB and mmap to 512MB
- Increase WAL checkpoint interval to 10000 pages
- Set page size to 8KB for better performance
- Increase busy timeout to 30 seconds
- Keep single connection to avoid SQLite locking issues
- DBHandler now only maintains asns and asn_peerings tables
- PrefixHandler maintains both prefixes and live_routes tables
- This consolidates all prefix-related operations in one handler
- Added new live_routes table with mask_length column for tracking CIDR prefix lengths
- Updated PrefixHandler to maintain live routing table with additions and deletions
- Added route expiration functionality (5 minute timeout) to in-memory routing table
- Added prefix distribution stats showing count of prefixes by mask length
- Added IPv4/IPv6 prefix distribution cards to status page
- Updated database interface with UpsertLiveRoute, DeleteLiveRoute, and GetPrefixDistribution
- Set all handler queue depths to 50000 for consistency
- Doubled DBHandler batch size to 32000 for better throughput
- Fixed withdrawal handling to delete routes when origin ASN is available
- Renamed BatchedDatabaseHandler to DBHandler
- Renamed BatchedPeerHandler to PeerHandler
- Quadrupled DBHandler batch size from 4000 to 16000
- Created new PrefixHandler using same batching strategy to maintain routing table in database
- Removed verbose batch flush logging from all handlers
- Updated app.go to use renamed handlers and register PrefixHandler
- Fixed test configuration to enable batched database writes
