## AI overview

Batch processing gathers data and runs bounded jobs, making it easier to operate, debug, rerun, and optimize for cost when results can wait. Streaming processes events continuously through a broker and stream processor, supporting timely fraud detection, monitoring, personalization, IoT reactions, and live dashboards, but adds ongoing operational challenges such as backpressure, state, recovery, ordering, and duplicates. Delivery choices involve tradeoffs: at-most-once can lose events, at-least-once can create duplicates, and exactly-once generally requires more coordination and state; idempotent processing can make retries safe. Choose based on how quickly each result must be useful, and combine streaming for urgent results with batch jobs for work such as reconciliation, reporting, and analytics.

The real tradeoff isn't just speed. It's what you give up to get it.
