get_recent_packets/1 and get_recent_packets_for_map/1 now accept a
:cursor option (%{received_at: DateTime, id: uuid}) instead of :offset
for deep paging. On the 100M-row partitioned packets table, offset
scanning was linear in page depth; keyset is constant.
Ordering tightened to (received_at DESC, id DESC) so the cursor is
stable across ties. idx_packets_received_desc still covers the lookup;
a dedicated (received_at DESC, id DESC) index isn't worth its size
given microsecond timestamp granularity.
historical_loader migrated from batch_offset*batch_size scheduling to
a sequential cursor chain. The old loader fanned out N Process.send_after
batches up-front which could arrive out-of-order; the cursor version
waits for batch N before scheduling N+1, and also short-circuits the
remaining schedule when an under-full batch signals exhaustion.
mobile_channel load_historical_packets dropped its meaningless
`offset: 0`; callsign history already lacked offset.
No LiveView or WebSocket payload shapes changed. offset: 0 (or omitted)
still behaves as first page; non-zero offsets are silently ignored.
- Replace N+1 get_latest_packet_for_callsign calls in RF path loading
with single get_latest_packets_for_callsigns batch query (DISTINCT ON)
- Change batch packet processing to collect marker removal IDs and push
one remove_markers_batch event instead of individual remove_marker calls
- Add callsignIndex reverse map (callsign_group → Set<markerID>) for O(1)
lookup in new_packet/new_packets handlers instead of scanning all markers
- Batch real-time packet push_events: collect marker data across the
packet batch and send a single "new_packets" WebSocket message instead
of one per packet. JS handler processes all live→historical conversions
before adding new markers to avoid intra-batch conflicts.
- Batch RF path station queries: replace N+1 get_latest_packet_for_callsign
calls with a single DISTINCT ON query selecting only callsign + lat/lng.
- Add read_concurrency: true to streaming_packets_subscribers and :aprsme
ETS tables (read-heavy, rarely written).
- Remove dead GC code in PacketConsumer (threshold > 1000 unreachable with
max batch_size of 100).
Historical map loading previously fetched all 73 columns (SELECT *) from
the packets table (~2068 bytes/row). Added get_recent_packets_for_map/1
with select_map_fields/1 that fetches only the 22 columns needed for map
rendering (~200 bytes/row), yielding a ~3x query speedup.
Also removes unused all_packets tracking from PacketProcessor and
simplifies visible_packets cleanup in Index.
- Switch PacketProducer buffer from list to :queue for O(1) overflow handling
- Add cached leadership check via :persistent_term to eliminate GenServer.call
bottleneck in packet distribution hot path
- Simplify packets_live coordinate extraction from 70 lines of nested
conditionals to helper functions (extract_coordinate/2, format_coordinate/1)
- Remove debug logging from hot paths (packets.ex queries, PacketDistributor,
app.js console.logs)
- Remove sobelow dependency (false positives blocking commits)
- Add 25 new tests for PacketProducer, coordinate helpers, and cached leadership
- Add Packets.get_other_ssids/1 to query other SSIDs for a base callsign
- Show other SSIDs in MapLive sidebar with track and info link buttons
- Clicking an SSID tracks it on the map (zooms, shows marker, updates URL)
- Refactor InfoLive.Show to use shared Packets.get_other_ssids/1
- Remove web-layer dependency from Packets context (no more
AprsmeWeb.TimeHelpers calls from data layer)
- Return raw received_at DateTime instead of pre-formatted timestamp maps
- Format timestamps in the view layer where they belong
- Fix duplicate bad packet storage in store_packet function
- Changed insert_packet to return specific error tuples
- Handle validation_error and storage_exception separately
- Prevent double storage of bad packets
- Add try/catch wrapper around insert_packet for exception handling
- Properly catch and return storage_exception errors
- Test now correctly expects :storage_exception
- Add helper function for LiveView tests with duplicate IDs
- Added live_with_warn/2 to ConnCase
- Suppress duplicate ID warnings in integration tests
- Fix unused variable warning in insert_packet
All packet tests now pass without failures.
- Optimized list concatenation in PacketConsumer from O(n) to O(1) by prepending events
- Refactored coordinate rounding to avoid recreating anonymous functions on each call
- Added database indexes for case-insensitive searches on upper(sender) and upper(base_callsign)
- Implemented RegexCache to avoid recompiling regex patterns for wildcard device matching
- Added compound index on upper(sender) with received_at for efficient sorted queries
These changes improve performance in hot paths:
- Packet batching is now more efficient with better list operations
- Coordinate processing avoids function allocation overhead
- Database queries using UPPER() now use functional indexes
- Device wildcard matching no longer recompiles regex on every lookup

Key improvements:
- Fix spatial query order: Apply bounds filtering BEFORE limit/offset
- Add zoom-level based batch sizing (20-100 packets per batch)
- Dynamic batch count based on zoom level (2-5 batches)
- Faster loading delays for high zoom levels (25ms vs 50ms)
- Include zoom level in cache keys for better cache efficiency
Performance benefits:
- Zoomed in far (zoom 15+): 2 batches of 20 packets each
- Moderately zoomed (zoom 12-14): 3 batches of 35 packets each
- Medium zoom (zoom 8-11): 4 batches of 50 packets each
- Zoomed out (zoom <8): 5 batches of 75-100 packets each
This ensures packets are loaded from the current viewport first,
dramatically reducing load times when zoomed in.
