Progressive Hints

Hint 1 (after 5 min)

Look at the revenue numbers. From Dec 3-7, daily revenue is $2.7M-$3.2M. On Dec 8-9, it drops to ~$290K — roughly 10x lower. But the job reports "SUCCESS." Something is wrong with the data, not the job execution.

Hint 2 (after 10 min)

Compare the record counts: Dec 7 processed 142,918 records. Dec 8-9 processed only 14,293 — exactly 10x fewer. The job connected to analytics-db:5432/warehouse both times. Now look at the log lines: on Dec 8, someone replaced the analytics-config ConfigMap. And there are two ConfigMap files — one for prod (warehouse) and one for staging (warehouse_staging). Both ConfigMaps have the same name and namespace.

Hint 3 (after 15 min)

This is a daily analytics rollup job that aggregates order and revenue data from a data warehouse. On Dec 8, someone applied the staging ConfigMap to the production namespace (both are named analytics-config in namespace analytics). But wait — the job log still shows DB_NAME: warehouse, not warehouse_staging. The staging database warehouse_staging is on the same host but has only test data (14,293 records vs 142,918 in production). Actually, re-read: both ConfigMaps point to DB_HOST: analytics-db — the staging ConfigMap just uses a different database name. The real question is: did someone apply the staging ConfigMap to prod, or did the staging database name get applied? The record count (14,293 on both Dec 8 and 9, identical) is the telltale — the job is processing the staging database.
