"""Celery task: refresh the sales-tracker MVs (Issue #61).
|
|
|
|
Scheduled via hardcoded beat entry in workers/beat_schedule.py:
|
|
'mv-sales-tracker-refresh-weekly' — weekly on Monday at 04:30 MSK.
|
|
|
|
Refreshes (both CONCURRENTLY, non-blocking):
|
|
- mv_sales_tracker_velocity_by_district (Site Finder Velocity Score, 4th criterion)
|
|
- mv_sales_tracker_absorption_curves (recommend_mix + sellout forecast foundation)
|
|
|
|
Both MVs are built from the Объектив sales-tracker ("шахматки") snapshots
|
|
(objective_lots / objective_lots_history). Source data refreshes via the
|
|
objective_sync beat job, so a weekly MV refresh keeps the aggregates current.
|
|
|
|
MV-source migration: data/sql/164_mv_sales_tracker_velocity_absorption.sql.
