- Fix score_pressure crash on nil pressure_mb (coastal HRRR points)
- Set 10-min timeout on grid score upsert transaction (was :infinity)
- Single DELETE for prune_old_scores instead of N queries in a loop
- Remove dead load_hrrr_refractivity that loaded 95k rows into nil map
- Pass selected_time to point_detail to skip latest_valid_time sub-query
- Batch station existence checks (1 query per path point, not per station)
- Batch solar index upserts via insert_all in chunks of 500
- Batch backfill_distances via single UPDATE FROM VALUES statement
- Add is_grid_point boolean + partial index to hrrr_profiles (replaces
non-sargable modular arithmetic filter on every weather map query)
- Add partial index on contacts(qso_timestamp) WHERE pos1 IS NOT NULL
- Move backfill enqueue to Oban worker so UI returns immediately
Removed n_live_tup > 0 filter that hid tables when pg_stats reports 0 rows
during VACUUM. Added dead tuple column with warning highlight to monitor
vacuum progress. Also includes Styler reformatting and unused dep cleanup.
ON CONFLICT now only replaces score/factors when the score actually changed,
avoiding dead tuple generation for the ~80% of grid points that don't change
between consecutive HRRR runs.
Migration sets aggressive autovacuum on propagation_scores: zero cost delay,
2000 cost limit, 1% scale factor. The table was at 72GB with 108M dead rows
because default autovacuum couldn't keep pace with 14M upserts per hour.
- Only deduplicate against active jobs (available/scheduled/executing/
retryable), not completed ones. Completed jobs no longer block new
inserts for the same args.
- Period reduced from 3600s to 300s
- Fixes contacts stuck in :queued with no actual Oban jobs
- Database triggers on contacts and oban_jobs fire pg_notify on
status/state changes
- RepoListener GenServer subscribes via Postgrex.Notifications and
broadcasts to PubSub
- Backfill dashboard subscribes to PubSub instead of 2-second polling
- Eliminates periodic SELECT queries, updates arrive instantly
