Both workers had unique: [period: 300] which only dedupes within a
5-minute window. Re-running the enrichment-enqueue script hours or
days later stacked identical jobs in the available queue — we found
~60k redundant weather + 3k redundant hrrr jobs in prod from the
March and April enqueue passes.
:infinity means Oban dedupes against every live job in the states
list regardless of age, so a second enqueue pass is a no-op as long
as the first pass's jobs haven't completed yet.
Aliases: add module aliases for 9 nested module references
Apply: replace apply/3 with direct module attribute calls
Line length: break 1 long spec line
Refactoring: extract helpers to reduce complexity and nesting
in show.ex, radio.ex, weather workers, terrain, duct detection,
backfill dashboard, contact map, and mix tasks
When ASOS/RAOB/IEMRE APIs return empty data, store a stub record so
dedup checks (has_surface_observations?, has_sounding?, has_iemre_observation?)
see coverage and don't recreate the same jobs on future backfill runs.
Backfill dashboard now has checkboxes to select which enrichment types
to process (HRRR, Weather, Terrain, IEMRE). Prevents weather jobs from
flooding the queue when only HRRR needs work.
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.
- 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
WeatherFetchWorker, HrrrFetchWorker, and TerrainProfileWorker now have
unique: [period: 3600] — Oban deduplicates identical jobs within 1 hour.
Repeated page loads won't queue redundant fetches.
- WeatherFetchWorker broadcasts on ASOS and RAOB completion
- Contact show page subscribes and reloads weather data on receipt
- Loading spinners for soundings and surface observations when queued
- Propagation analysis recomputed with new sounding duct data
20 attempts with exponential backoff capped at 6 hours ensures
data is eventually fetched even during extended rate limiting or
API outages (~3 days of retrying before giving up).
IEM was returning 503s under 10 concurrent workers. Three fixes:
- Req transient retry with exponential backoff on IEM requests
- WeatherFetchWorker Oban job retries failed ASOS/RAOB fetches 2-3h later
with random jitter to avoid thundering herd
- Import script concurrency reduced 10→5, weather queue capped at 3
