ETL Queue

exframe-etl-queue is a queue-based ETL step processor for Node.js (v18+), version 3.1.6. It manages enqueuing messages during extraction, automatically advancing them through ETL steps (Extract, Transform, Load) upon acknowledgment. Key differentiator vs generic queues is built-in ETL step lifecycle and error handling (messages go to error state on failure). Requires peer dependencies exframe-db 4.x and exframe-logger 3.x. Ships TypeScript types and uses CommonJS (require). Release cadence is not documented but based on semver.
