Start with the required timing
Some processes need an update immediately after an event; others are accurate and useful when consolidated on a schedule. Avoid real-time complexity when the business process does not require it.
Consider volume and recovery
Batch jobs can simplify high-volume reconciliation, while events can reduce delay for individual transactions. Both need retry, monitoring and a way to recover from partial failure.
Design the operating model
The pattern determines more than technology. It affects who monitors failures, how late data is handled and how downstream teams understand processing status.
Practical example
Example: inventory availability
If a sales channel needs a current availability signal before confirming an order, event-driven updates may be appropriate. A nightly planning extract may remain better suited to a batch schedule.
Best practices
Put the fundamentals in place.
- State the business freshness requirement in plain language.
- Design retries and reconciliation before production release.
- Monitor backlog, late processing and failed records against agreed thresholds.
Frequently asked questions
Is event-driven integration always faster?
It can reduce delay, but end-to-end timing also depends on processing, downstream availability and failure handling.
Can a process use both patterns?
Yes. A business process may use events for immediate updates and batches for reconciliation or reporting.
