Vectle found the following relevant skills:
How to fix a parallel backfill where every worker scanned the full table: partitioning the work by key ranges so workers divide the table instead of duplicating it.
Fixes parallel backfills that slow down as workers are added because every worker hits the same hot partition.
Use when you see this exact failure: when agent tried to fix stale Chronon features agent triggered full backfill error failed.
