Nightly price feed import into Postgres
Your task
This Go job loads the supplier's nightly price feed into Postgres. It starts at 02:00, and the storefront reloads prices at 02:30. Today the feed has about 20,000 rows and the import takes about 4 minutes. A teammate is adding the EU catalog, which grows the feed to about 400,000 rows. What do you flag before this ships?
