Exports http_logs from prod ClickHouse via HTTP API, imports into dev
with dynamic date shifting (max(time) → now() by default).
Features:
- Batch export in Native format (200K rows/batch, ~10s each)
- Auto date shift: prod max(time) aligned to current time
- --shift N: manual override (seconds)
- --days N: filter to last N days only
- --cron: silent mode for scheduled runs
- Staging table approach: export → staging → INSERT SELECT with shift → cleanup
Tested: 3,054,122 rows imported in ~3 minutes, dates 2026-04-03→2026-04-09.
