Node.js job design for LLM catalog backfill with durable ledger

This article details a robust approach for backfilling a customer-support catalog using a Node.js bulk job, emphasizing the creation of a durable ledger to track every classification and usage record. It advocates for making tenant cost visibility a primary product feature by recording token counts alongside decisions, rather than in a separate dashboard. The proposed method involves a four-stage process: source, ledger, classifier, and export, ensuring that each step is restartable and results are committed to the ledger before exporting, thereby handling potential failures like rate limits or process exits.
